Outer Continental Shelf (OCS) oil and gas exploration and development have been under way in the Pacific (Southern California) Region since 1966. During that time, there have been four Federal lease sales: in 1966, 1968, 1975 (Sale 35), and 1979 (Sale 48). Oil and gas production from three leases has been going on since 1968. It peaked in 1971 and now averages around 31,400 barrels of oil and 15.4 million cubic feet of gas per day. Discoveries on areas leased in the 1968 and 1975 sales have led to plans for eight new platforms to begin production in the early 1980's. Five platforms are in the eastern end of Santa Barbara Channel, one is in the western Channel, and two are in San Pedro Bay, south of Long Beach. Three rigs are doing exploratory drilling in the Region.
\nThe most recent estimates by the U.S. Geological Survey of remaining reserves for all identified fields in the Southern California Region are 695 million barrels of oil and 1,575 billion cubic feet of gas (January 1979). The USGS has also made risked estimates of economically recoverable oil and gas resources for all the leased tracts in the Region (March 1980). These risked estimates of economically recoverable resources are 394 billion barrels of oil and 1,295 billion cubic feet of gas. The USGS estimates of undiscovered recoverable resources for the entire Southern California OCS Region (January 1980) are 3,200 million barrels of oil and 3,400 billion cubic feet of gas.
\nBecause of the long history of oil and gas production in Southern California from wells onshore and in State waters, there are many existing facilities for the transportation, processing, and refining of oil and gas. Some of the expected new OCS production can be accommodated in these facilities. Four new onshore projects will be required. Two of these are under construction: (1) a 9.6-km (6-mi) onshore oil pipeline (capacity: 60,000 bpd) between Carpinteria (Santa Barbara County) and the existing Mobil-Rincon separation and treatment facility (Ventura County), and (2) a small supply base and dock (upgrade of existing facility) and a 0.4-hectare (1-acre) crude oil distribution facility in Long Beach (Los Angeles County), connected to landfall by a 3-km (1.8-mi) onshore pipeline. The two other facilities are awaiting permit approval: (1) a gas treatment plant at Las Flores Canyon (Santa Barbara County) and (2) a separation and treatment plant at Mandalay Beach (Ventura County) with 4 km (2.5 mi) of onshore pipeline on the same right-of-way from landfall to the plant and from the plant to an existing gas transmission line.

The area surveyed is located in the western San Juan Mountains near Lake City, Colorado. The general area covered is between 37°45' and 38° latitude north and 107°15' and 107°35' longitude west. The survey flying was confined to nine valleys which surround the Lake City caldera. Four blocks were surveyed from October 22 to October 27, 1979 for a total of 535 line - kilometers. The survey was flown as part of a mineral appraisal study conducted in cooperation with Bureau of Land Management (BLM). The survey was done to detect massive mineralization, mainly copper, and to locate conductive faults that may be suitable sites for uranium mineralization.
To be useful, airborne electromagnetic measurements must be made within a few hundred feet of the surface. The area that was flown is so rugged that a helicopter rather than a fixed-wing aircraft was used.
Fraser and Dvorak summarize the data of the survey areas as follows: in the east and south, the ground resistivities varied over a broad range—, from 20 to 1000 ohm-m. The western and northern parts of the area were characterized by resistivities mostly in the 300 to 1000 ohm-m range. Several weak to moderate EM anomalies were located that may warrant ground follow-up work.

Sound, Mass., by the U.S. Geological Survey in cooperation with the New England Division of the U.S. Army Corps of Engineers. These data were obtained during the August 1976 cruise of the B./V A. E. VERRILL as part of a continuing regional study of the Massachusetts offshore area to determine the suitability and potential environmental effect of ocean dumping of large volumes of harbor dredge-spoil material.
Specifically, as part of a proposed Federal Harbor improvement and maintenance dredging of Fall River and Mt. Hope Bay, Mass. under the jurisdiction of the Army Corps of Engineers, the disposal of the resultant dredge spoil is planned for an ocean dump site located in eastern Rhode Island Sound. The proposed site is also under consideration as a \"regional\" disposal grounds to be utilized by State and private organizations performing dredging work authorized by the Corps.
The data were obtained by using a Klein Side Scan Towfish* (sonar frequency, 100 kHz; pulse length, 0.1 msec). Signal returns from the starboard and port scans were automatically tuned, texture-enhanced, and printed centerout on 2 channels of a 3-channel Klein* wet-paper graphic recorder. Scan ranges of 75 m and 150 m were used. For comparison of graphic display, incoming signals from the starboard scan were also recorded on the third channel using a manual (nonautomatic) tuning mode. Navigational control was provided by Loran -C (positional accuracy within 0.2 km). Positional information was logged at 15-minute intervals and at major course changes.
The original records may be examined at the Data Library, U.S. Geological Survey, Woods Hole, MA 02543. Microfilm copies of the data are available for purchase from the National Geophysical and Solar-Terrestrial Data Center (NGSDC), Boulder, CO 80302.

A summary of hydrologic testing in an offshore oil-test well drilled for Tenneco, Inc. 55 miles east of Fernandina Beach, Florida, is presented. The interval tested (1,050 to 1,070 feet below sea level) is in a calcarenite that is equivalent to the Ocala Limestone (late Eocene) of onshore Florida and South Georgia. At this site the Ocala forms the highly productive Tertiary limestone aquifer system of the southeastern United States. Pressure-head measurements indicate an equivalent freshwater head of 24 to 29 feet above sea level. These pressure-head measurements and an earlier one made in the nearby JOIDES J-1 hole are the only hydraulic head determinations to date in the offshore extensions of any of the aquifers underlying the Atlantic coastal plain.
A drill-stem test recovered water samples containing about 7,000 milligrams per liter chloride. However, seawater used in the drilling process apparently contaminated the samples and the formation water is considered slightly fresher.
The head and salinity data from the Tenneco well suggest that the sampled interval lies in the transition zone between fresh and seawater in the limestone aquifer. These data, when viewed with similar data from JOIDES J-1, show the transition zone to slope very slightly landward. Heads at both wells are compatible with the onshore flow system as it existed prior to development.

In October 1977, the program was extended southeastward along the rift zone to the Valyermo area. In November 1977, the monitoring of water wells along the San Jacinto fault was initiated with the expectation of experiencing a moderate size earthquake while monitoring was in progress. Currently over thirty wells are being monitored. Eleven wells are monitored continuously with Stevens Type F recorders, two of which have been modified to operate with the Caltech Remote Observatory Support Systems (TIMS). The remaining wells are probed weekly, or in some cases semi-weekly or daily, by volunteers. We are endeavoring to improve the volunteer program by increasing the frequency of measurements and simplifying the procedure to minimize measurement errors. Weekly water-level data are displayed on computer-generated hydrographs for each well. Rainfall and earthquakes are plotted on the graphs for direct comparison with water levels. The hydrographs are updated and reviewed weekly. Weekly hydrographs are also prepared from recorder charts on two wells maintained by W. R. Moyle, Jr., of the U.S. Geological Survey, Water Resources Division Office, Laguna Niguel, California. A M5.5 earthquake occurred on 25 February 1980, between the Buck Ridge and San Jacinto strands of the San Jacinto fault zone, about 8 miles east-southeast of Anza. This is the largest earthquake which has occurred on the faults within our monitoring network. The Stevens recorder chart for well number 11S/6E-3N4 located in Borrego Valley about 20 miles southeast of the epicenter indicates that, during a period of about four hours on 21 February, the water level rose 1.5 to 1.6 feet and returned to its prior level. This is one of the most remarkable short-term water-level fluctuations observed during our monitoring program; it occurred about 88 hours prior to the earthquake. This well has been monitored since October 1977 and has had a Stevens recorder since October 1978. Long-term water levels have been remarkably steady compared to those in other wells we are monitoring. This well shows a strong response to earth tides. The Stevens record on a second well in Borrego Valley (11S/6E-1C1) showed a much smaller (0.1 foot) spike in water level at the same time as the spike in well number 11S/6E-3N4. Other continuously recording wells in Anza and Ocotillo Wells showed no identifiable water-level anomalies. The two wells in Borrego Valley which showed possible strain-induced water-level spikes appear to be more sensitive to earth tides than wells in the same area which did not show spikes in water level. We cannot conceive of any nontectonic cause for the spike on the Stevens record of well 11S/6E3N4. A creep event on the Coyote Creek fault about four miles from the well is one possibility. Because the spikes in the two wells in Borrego Valley are unique for the long-term record of these wells, they may represent precursors to the 25 February earthquake. Local seismic activity was also recorded in water levels of the two wells in Borrego Springs with continuous water-level recorders. One well showed peculiar high frequency water-level fluctuations from 22 July to 21 August 1980; since then the record has appeared normal. Several wells in the Palmdale-Valyermo area have shown peculiar changes in water level within the past year or so. The long-term hydrograph of well number 5N/12W-4H1 shows the most unusual behavior. The well showed no response to the 1977 and very heavy 1978 rainstorms, yet began to rise in early 1979 and continued to rise through the dry season of 1979. By comparison, most wells show a more normal seasonal response to rainfall. Eight wells in the Palmdale-Valyermo area have shown water-level changes which are different than would have been predicted from the previous history of water-level changes and seasonal rainfall. A longer period of observation is required to determine whether the changes are anomalous. Changes in the strain pattern and other geophysical phenomena have also been observed in southern California during about the same period as the water-level changes. If the water-level changes are the result of tectonic strain, the mechanism and significance are unknown. However, it is interesting that five of the eight wells with possibly anomalous water-level changes have been identified as good strain meters based on their response to earth tides. Six wells showing an unexpected rise in water level are located west of the earthquake swarm which occurred in 1976-1977 (McNally et al, 1978), whereas the two which show water levels lower than would have been predicted are located east of the earthquake swarm.

The aquifer is being increasingly developed for irrigation.
\nDuring the drought of 1976, nearly 24,000 acre-feet of ground water was withdrawn for irrigation, more than double that of the previous year. The number of irrigation pumping centers more than doubled from 1975 to 1977. Nearly all water is pumped from drift aquifers, except in the eastern parts of Sherburne and Wright Counties, where Paleozoic sandstone beds are a reliable source.
\nPhysical and hydrologic properties of the surficial aquifer were determined by test augering, pumping tests, and laboratory sieve analyses. The aquifer is predominantly medium to coarse sand with lesser amounts of gravel in much of the study area. The Sauk River valley in Stearns County is nearly 50 percent poorly sorted gravel of irregular thickness. Saturated thickness of sand in the Maine Prairie area locally exceeds 100 feet, and transmissivity exceeds 40,000 feet squared per day. Similar deposits in Sherburne County exceed 80 feet in thickness, transmissivity exceeds 30,000 feet squared per day, and wells theoretically could yield 2,000 to 3,000 gallons per minute. Theoretical well yields of less than 100 gallons per minute can be expected where saturated thickness is less than 20 feet and transmissivity is less than 5,000 feet squared per day. Pumping tests indicate horizontal to vertical ratios of hydraulic conductivity ranging from 2-27:1.
\nAverage annual precipitation is 27 inches, about 8 of which is recharge to the surficial aquifer. Regional ground-water movement is toward the Mississippi River, which transects the area. Tributary streams and lakes act as controls for local flow systems. At extreme low flow in August 1976, mainstem gains in streamflow in the Elk, St. Francis, Sauk, and Mississippi Rivers averaged 0.4, 0.4, 0.2, and 2.5 cubic feet per second per river mile, respectively.
\nGround water is of the calcium bicarbonate type and is suitable for most uses. Relatively high nitrate and chloride concentrations occur in a heavily irrigated area in Sherburne County.
\nSurficial aquifers in Sherburne County and the Maine Prairie area of Stearns County were simulated by two-dimensional digital ground-water-flow models. Calibration was achieved by matching calculated water-table heads and streamflow gains with observed field values. Aquifer responses to pumping stresses under present and hypothetically expanded development were determined for average and below average recharge conditions.
\nIrrigation withdrawals for 1977 totaling 15.6 cubic feet per second from 96 pumping centers were included in the Sherburne steady-state model. Increasing withdrawals to 52.2 cubic feet per second from 153 pumping centers would lower regional water levels as much as 8 feet within a few years at normal recharge rates.
\nIrrigation withdrawals in 1977, totaling 2.0 cubic feet per second from 19 pumping centers, were included in the Maine Prairie steady-state model. Increasing withdrawals to 10.8 cubic feet per second from 42 pumping centers would lower regional water levels as much as 18 feet at normal recharge rates.
\nBoth modeled areas will support additional withdrawals, but caution must be exercised because lowering ground-water levels will also lower lake levels and reduce streamflow. In some areas, aquifer dewatering will reduce individual well yields.

A field trip road log provides directions for access to type and/or reference localities for each formation discussed.
Tertiary rocks of southwestern Washington, measuring nearly 13,000 feet in thickness, are mapped as thirteen formational units. These units crop out within several structural basins formed along the tectonically active Pacific margin of the North American Plate. Thick Quaternary sands and gravels of glacial and fluvial origin and a heavy vegetational cover restrict exposures to stream and river banks, highway, road and railroad cuts, and occasional steep hillsides.
The Tertiary strata are predominantly marine sedimentary rocks with interbedded volcanics and eastwardly increasing amounts of nonmarine strata. Age equivalent and genetically similar sequences occur throughout the Coast Ranges of western Oregon and Washington.

The number of samples from each State are: Pennsylvania, 132; Ohio, 101; Maryland, 25; West Virginia, 254; Virginia, 33; Indiana, 49; Massachusetts, 5; and Rhode Island, 10. The analytic data are filed in the National Coal Resource Data System of the U.S. Geological Survey.
The U.S. Geological Survey has quantitatively determined 35 major, minor, and trace elements in each sample. Tests were also made for 35 other trace elements using semi-quantitative spectrographic methods. In addition, the Coal Analysis Section of the U.S. Department of Energy has determined proximate and ultimate analyses, 3cu, forms of sulfur, free-swelling indexes, and ash-fusion temperatures on 563 of the 659 samples.
Comparison of the geometric means of the 644 bituminous coal samples of this report with an additional 968 bituminous coal samples of the eastern United States reported by Swanson and others in 1976 and by Zubovic and others in 1979 is shown in tables 2a-c. As shown by the means for ultimate and proximate analyses, small differences exist between the two sets of data; however, only the moisture and oxygen contents are significantly different. The forms of sulfur, ash-fusion temperature and heat of combustion are similar. The means for the major and minor oxides in ash are similar for SiO2, K2O, Fe2O3, TiO2, MgO, and P2O5 are lower, whereas, MnO is higher in the analyses of the samples of this report.

Within the mapped area the shelf ranges in width from a minimum of 4 km to a maximum of 18 km. Clover (1971, p. 89) named the shelf for the prominent Isla Caja de Muertos, a small upfaulted block of lower and middle Tertiary rocks located near the center of the map area. The Isla Caja de Muertos shelf is not known to be bounded by faults, though Glover suggested faults on the west and south boundaries, and the bathymetry of the insular slope reveals a large east-west fault about 6 to 8 km south of the shelf edge.

Holocene estuarine silt and clay cover most of the bay floor; relict eolian and deltaic sand occurs along the eastern shore; sandy patches are present in the main channel owing to higher tidal current velocities. Organic content is high along the western shore, where tidal flats are extensive, and in the slough at the mouth of Coyote Creek where wastewaters discharge.
\nThirty-one species of benthonic foraminifera were identified in surficial sediments of San Francisco Bay estuary; of these, 20 species were stained red by rose Bengal and are considered as live. Water depth, sediment textural characteristics, salinity, organic matter, sediment pH, and biological competition were considered as factors that might affect distribution of foraminifera. Four ecologic zones based on observed trends in the distribution and abundance of several species correlate well with some environmental factors. Four groups based on the Q-mode analysis of frequency counts of foraminiferal assemblages are reasonably similar to the four ecologic zones. These zones, showing restricted depth ranges, are: Inner Coastal Zone, where Elphidium incertum obscurum and Trochammina infiata are prominent; Outer Coastal Zone, dominated by Ammonia beccarii tepida and Elphidium incatum; Deep Bay Zone, where Elphidietla hannai, Elphidium incertum clavatum, Hopkinsina pacifica, and Bolivina spp. appear in abundance; and Deep Channel Zone, where Elphidiella hannai is most abundant. In the Inner Coastal Zone, salinity due to large fluctuations is a limiting factor for many species. Substrate textural characteristics are primary determinants of the distribution of agglutinated foraminifers. The percentage of organic matter in the sediment correlates well with the abundance of Elphidium incertum obscurum, a ubiquitous species in San Francisco Bay. Sediment pH is not critical. Biologic competition can be estimated by comparing the percentage of a species with the number of species present in the assemblage, as shown for Ammonia beccarii tepida and Elphidiella hannai.

Pleistocene sea-level lowering and/or post-Pleistocene bottom water temperature increases may have had a significant role in this process.

Within this succession, three lithotectonic units, or sequences of rock that were deformed semi-independently of each other, have somewhat different structural characteristics. Both the Alleghenian and Taconic orogenies have left their imprint on the rocks. Wind and water gaps are structurally controlled, thus placing doubt upon the hypothesis of regional superposition. Wisconsinan deposits and erosion effects are common. We will examine these geologic features as well as some of the economic deposits in the area.

The complex consists of the following subdivisions: Lac La Croix Granite, granite-rich migmatite, schist-rich migmatite, quartz-feldspar gneiss, hornblende quartz diorite and diorite, granodiorite and trondhjemite, amphibolite and amphibolite migmatite, older migmatite, biotite schist, Burntside Gneiss, and pegmatite. Because the name Vermilion Granitic Complex is proposed as a more inclusive group term, the more restricted name Vermilion Granite (Grout, 1923) is hereby abandoned. The new name Lac La Croix Granite is proposed for the uniform, light-pink biotite granite that occurs widely in the eastern and central parts of the complex. It is denned as having less than 5 percent of schistose or gneissic inclusions and is therefore more restricted than the Vermilion Granite of Grout (1926), which included substantial amounts of migmatitic rocks. The name Burntside Gneiss is adopted as a replacement for the older term Burntside Granite Gneiss, originally named by Grout (1926). This change is required by the conclusion that the rock is a metamorphosed dacite and not a metamorphosed granite, as formerly interpreted.

Underlying the glacial deposits are sedimentary rocks of Mississippian and Devonian age. The youngest of these rocks are the sandstones of the Marshall Formation in the western part of the county; the oldest are the limestones of the Detroit River Group in the southeast corner.
Sand and gravel deposits in some places in the county may yield more than 500 gallons per minute of water. Approximately 50 percent of the wells tapping the Marshall Formation, the most reliable bedrock aquifer, can yield as much as 60 gallons per minute.
Washtenaw County has sand and gravel deposits that are more than 50 feet thick. The deposits are mined in several areas and are of economic importance. In addition, there may be potential for peat production in the western part of the county and for clay production in the eastern part.

An analysis of the general stages in the evolution of petroleum production and discovery and of industry statistics provides an estimate of when the stage characterised by increasing production in the market economy countries outside the United States and Canada will end. The analysis indicates that the year of maximum production will be in the 1990s. Economic growth aggravates the difficulties accompanying the production decline by advancing the date of peak production and by increasing the adjustments that must be made as oil production declines.

A basement complex of pre‐Cenozoic plutonic and metamorphic rocks is partly buried by ∼35 km3 of late Cenozoic volcanic rocks that were erupted during two periods, as defined by K‐Ar dating: (1) 4.0–2.5 m.y., ∼31 km3 of basalt, rhyodacite, dacite, andesite, and rhyolite, in descending order of abundance, and (2) ≤1.1 m.y., nearly equal amounts of basalt and rhyolite, most of the rhyolite being ≤0.3 m.y. old. Vents for the volcanic rocks of the younger period are localized on and near a horst of basement rocks within a concavity defined by the distribution of vents of the older period. The alignment of many vents and the presence of a considerable number of roughly north‐trending normal faults of late Cenozoic age reflect basin and range tectonics dominated by roughly east‐west lithospheric extension. Fumaroles, intermittently active thermal springs, and associated altered rocks occur within and immediately east of the central part of the field of Quaternary rhyolite, in an area characterized by various geophysical anomalies that are evidently related to an active hot‐water geothermal system. This system apparently is heated by a reservoir of silicic magma at ≥8‐km depth, itself produced and sustained through partial melting of crustal rocks by thermal energy contained in mantle‐derived basaltic magma that intrudes the crust in response to lithospheric extension.

Cores of noncalcareous shale of largely nearshore-marine origin were obtained from the Frontier Formation and the overlying Cody Shale at depths of 3,780.6 to 3,879.9 m in Converse County, near the axis of the Powder River basin, and at depths of less than 320 m in Johnson County, on the western flank of the basin. Cores of calcareous and noncalcareous shale representing offshore-marine and nearshore-marine environments were acquired from the Belle Fourche Shale, Greenhorn Formation, and Carlile Shale at depths of less than 270 m in Weston County, on the eastern flank of the Powder River basin. Analyses of the shale for organic carbon content, total pyrolytic hydrocarbon yield, volatile hydrocarbon content, temperature of maximum pyrolytic yield, and vitrinite reflectance indicate that the amount and character of the organic matter in the sampled rocks is related to the content of calcium carbonate, the depositional environment, and the burial depth of the strata. On the east flank of the Powder River basin, calcareous shale of offshore-marine origin contains abundant hydrogen-rich organic matter derived mainly from aquatic plants. Noncalcareous shale of largely nearshore-marine origin, on the west flank of the basin, locally contains significant hydrogen-poor organic matter derived mostly from land plants. The noncalcareous, nearshore-marine shale in the middle of the basin probably contained similar amounts of hydrogendeficient organic matter prior to deep burial and thermal alteration. The calcareous shale in Weston County is a potentially rich source of oil and gas, but it is thermally immature and is in a very early stage of the hydrocarbon-generation process. The noncalcareous shale in Johnson County is a potential source rock for gas, but also is in an early stage of thermal alteration. In Converse County, the sampled beds are thermally mature and have generated hydrocarbons. The extent of this contribution of hydrocarbons to the commercial petroleum occurrences of the area can be inferred from the composition of the original organic matter in the beds. Furthermore, the degree of thermal alteration of the organic matter at these localities indicates that the depth of the sampled strata was never as great on the flanks of the Powder River basin as in the basin center.
