The Worley Ridge Roadless Area includes about 3,000 acres of Chattahoochee National Forest land in Rabun County, Ga. The area is underlain mostly by meta-arkose of the Tallulah Falls Formation that grades upward into a mixed-rock unit of interlayered mica schist, amphibolite, and metasandstone in the northwest corner. Abundant rock suitable for rough building stone and crushed rock, and an estimated 3,400 short tons (3,000 metric tons) of coarse-grained kyanite in soil and alluvial deposits are the only identified mineral resources. Oil and gas have an unknown potential. All surface and mineral rights are under Federal ownership.

Contrary to the contention that channel gravels are being covered by fine-grained sediment, examination of the river channel at several sites indicates that bed sediment is generally a thin veneer ( < 0.6 ft) over local bedrock. This thin sediment veneer and numerous streambed exposures of local bedrock suggest that bed material commonly is redistributed and that most fine-grained sediments probably have a short residence time and are transported through the study reach. The Shields criterion for bedload transport suggests that maximum discharges for the Deschutes River upstream from Pringle Falls subsequent to the operation of Wickiup Dam could transport bed material about 20% layer (up to about 17 mm) than pre-closure maximum discharges. Minimum discharges subsequent to dam closure, however, appeared capable of transporting only particles about one-half as large (up to about 6 mm) as pre-closure minimum discharges. Operation of Wickiup Dam appears to have had little effect of the size of transported bedload in the Deschutes River near Benham Falls. Bank erosion, averaging 0.2 to 0.4 ft/year, appears to have started subsequent to the operation of Wickiup Dam and may have resulted from changes in the timing of high and low stages. Most of the eroded material is fine grained ( < 2 mm). Shields ' bedload transport criteria suggest that this sediment should move through the upper Deschutes River and not cause appreciable sedimentation on the channel bed. Substantial alteration of river stage following dam closure has resulted in subaerial exposure of channel bar gravels during the brown trout spawning season, which lasts from October through December in the upper Deschutes basin. This factor, combined with a lack of gravel in the deeper part of the channel, appears to be a major contributor to reduction of the brown trout spawning habitat in the upper Deschutes River.

The extensometer, which partially penetrates the compressible sediments, recorded 0.82 m of compaction during the same period. By use of a one-dimensional model, cumulative daily compaction values were simulated to within an average of 0.0038 m of the actual values. Land subsidence was simulated to within an average of 0.011 m using the same model in conjunction with geohydrologic data of the sediments below the extensometer. A highly compressible clay layer that is 24.38 m thick was partially penetrated by the extensometer. The simulation indicated that the layer was driving compaction and land subsidence linearly with respect to time, despite the presence of other compacting layers. Because of its thickness and compressibility, this layer can be expected to continue to compact after applied vertical stresses have stopped increasing and other layers have stopped compacting. Sensitivity analysis indicated that the compressibility of fine-grained sediments (expressed as specific storage) is one of the factors to which compact is most sensitive. Preconsolidation stress and hydraulic conductivity also affect land subsidence near Eloy, Arizona.

The hydrologic system has been subdivided into three aquifers: the Elm, Middle James, and Deep James. These sand-and-gravel outwash aquifers generally are separated from each other by till or other fine-grained sediments. The Elm aquifer is the uppermost and largest of the aquifers and underlies about 204 sq mi of the study area. The maximum altitude of the top of the Elm aquifer is 1,400 ft and the minimum altitude of the bottom is 1,225 ft. The Middle James aquifer underlies about 172 sq mi of the study area. The maximum altitude of the top of the Middle James aquifer is 1,250 ft and the minimum altitude of the bottom is 1 ,150 ft. The lower-most Deep James aquifer was not evaluated. The quality of the water from the Elm and Middle James aquifer varies considerably throughout the study area. The predominant chemical constituents in the water from the aquifers are sodium and sulfate ions; however, calcium, magnesium, bicarbonate, or chloride may dominate locally. The calculated theoretical total well yield from the Elm and Middle James aquifers ranges from a minimum of 64 cu ft/sec, which may be conservative, to a maximum of 640 cu ft/sec. Based on available data, yields of 100 to 150 cu ft/sec probably can be obtained from properly sited and constructed wells. The feasibility of artificially recharging an aquifer, using the technique of water spreading, depends on the geologic and hydraulic characteristics of the aquifer and of the sediments overlying the aquifer through which the recharge water must percolate. The sites suitable for artificial recharge in the study area were defined as those areas where the average aquifer thickness was > 20 ft and the average thickness of the fine-grained sediments overlying the aquifer was < 10 ft. Using these criteria, about 14 sq mi of the study area are suitable for artificial recharge. Infiltration rates in the study area are estimated to range from 1.3 to 4.3 ft/day. Using an infiltration rate of 2 ft/day, a spreading pond with an area of 0.16 sq mi would be required to artificially recharge at a rate of 100 cu/sec/m.

The analytical work was designed to test the homogeneity of constituents in three new NBS reference clays, NBS-97b, NBS-98b, and NBS-679. The analyses of variance of 276 sets of data for these three standards show that the constituents are distributed homogeneously among bottles of samples for 94 percent of the sets of data. \r\n\r\nThree of the reference samples (NBS-97, NBS-97a, and NBS-97b) are flint clays; four of the samples (NBS-98, NBS-98a, NBS-98b, and IPT-32) are plastic clays, and three of the samples (NBS-679, IPT-28, and IPT-42) are miscellaneous clays (both sedimentary and residual). Seven clays are predominantly kaolinite; the other three clays contain illite and kaolinite in the approximate ratio 3:2. Seven clays contain quartz as the major nonclay mineral. The mineralogy of the flint and plastic clays from Missouri (NBS-97a and NBS-98a) differs markedly from that of the flint and plastic clays from Pennsylvania (NBS-97, NBS-97b, NBS-98, and NBS-98b). \r\n\r\nThe flint clay NBS-97 has higher average chromium, hafnium, lithium, and zirconium contents than its replacement, reference sample NBS-97b. The differences between the plastic clay NBS-98 and its replacement, NBS-98b, are not as pronounced. The trace element contents of the flint and plastic clays from Missouri, NBS-97a and NBS-98a, differ significantly from those of the clays from Pennsylvania, especially the average rare earth element (REE) contents. The trace element contents of clay sample IPT-32 differ from those of the other plastic clays. IPT-28 and IPT-42 have some average trace element contents that differ not only between these two samples but also from all the other clays. IPT-28 has the highest summation of the average REE contents of the 10 samples. The uranium content of NBS-98a, 46 parts per million, is very much higher than that of the other clays. \r\n\r\nPlots of average REE contents of the flint and plastic clays, normalized to chondritic abundances, show that the clays from Missouri differ from the same types of clay from Pennsylvania. The plot of REE contents for the miscellaneous clays shows that the normalized means for the elements lanthanum through samarium for IPT-28 are much greater than those for the other miscellaneous clays. The means for the elements europium through lutetium are similar for all three miscellaneous clays.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/cir957","usgsCitation":"Hosterman, J.W., Flanagan, F., Bragg, A., Doughten, M., Filby, R., Grimm, C., Mee, J.S., Potts, P., and Rogers, N., 1987, Mineralogy and instrumental neutron activation analysis of seven National Bureau of Standards and three Instituto de Pesquisas Tecnologicas clay reference samples: U.S. Geological Survey Circular 957, iv, 38 p. :ill., map ;27 cm., https://doi.org/10.3133/cir957.","productDescription":"iv, 38 p. :ill., map ;27 cm.","costCenters":[],"links":[{"id":124633,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/1987/0957/report-thumb.jpg"},{"id":31462,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/1987/0957/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699e44","contributors":{"authors":[{"text":"Hosterman, John W.","contributorId":48962,"corporation":false,"usgs":true,"family":"Hosterman","given":"John","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":148921,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Flanagan, F.J.","contributorId":50139,"corporation":false,"usgs":true,"family":"Flanagan","given":"F.J.","email":"","affiliations":[],"preferred":false,"id":148922,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bragg, Anne","contributorId":78600,"corporation":false,"usgs":true,"family":"Bragg","given":"Anne","email":"","affiliations":[],"preferred":false,"id":148923,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Doughten, M.

The principal aquifer system in the Socorro and La Jencia Basins consists of, in descending order, the shallow aquifer, the Popotosa confining bed, and the Popotosa aquifer. The minor aquifer systems, which are dominant along the basin margins, are the Socorro volcanics aquifer system and the Mesozoic-Paleozoic aquifer system. On the east side of the Socorro Basin, water enters the principal aquifer system from the Mesozoic-Paleozoic aquifer system. On the west side of the Socorro Basin, groundwater flows from the principal aquifer system in La Jencia Basin eastward to the principal aquifer system in the Socorro Basin. The volume of this flow is limited by the permeability of the minor aquifer systems and the Popotosa confining bed. A water budget indicates that if no change in groundwater storage occurs in the Socorro Basin, groundwater inflow to the basin is about 53,000 acre-feet per year greater than groundwater outflow. Dissolution of gypsum, calcite, and dolomite seems to control water quality in the Mesozoic-Paleozoic aquifer. Water with a chloride concentration of as much as 1,000 milligrams per liter and a specific conductance of as much as 6,700 microsiemens per centimeter at 25 C is present in the northern and southern parts of the Socorro Basin. These large chloride concentrations may indicate upward movement of water from deeper in the basin in these areas. The water with the large chloride concentration in the southern part of the basin also may be caused by leakage of geothermal waters along the Capitan Lineament. In the central part of the Socorro Basin, infiltration of excess irrigation water and inflow of groundwater from the basin margins control water quality. In this area, specific conductance generally is less than 1,000 microsiemens per centimeter. Water in La Jencia Basin generally is of the calcium sodium bicarbonate type with specific conductance less than 500 microsiemens per centimeter.

Geologic data from more than 500 water supply and test wells were analyzed to define characteristics of the basin sediments that may affect the potential for land subsidence induced by groundwater withdrawal. The Tucson basin is a structural depression within the Basin and Range physiographic province. The basin is 1,000 sq mi in units area and trends north to northwest. Three Cenozoic stratigraphic unit--the Pantano Formation of Oligocene age, the Tinaja beds (informal usage) of Miocene and Pliocene age, and the Fort Lowell Formation of Pleistocene age--fill the basin. The Tinaja beds include lower, middle, and upper unconformable units. A thin veneer of stream alluvium of late Quaternary age overlies the Fort Lowell Formation. The Pantano Formation and the lower Tinaja beds accumulated during a time of widespread continental sedimentation, volcanism, plutonism, uplift, and complex faulting and tilting of rock units that began during the Oligocene and continued until the middle Miocene. Overlying sediments of the middle and upper Tinaja beds were deposited in response to two subsequent episodes of post-12-million-year block faulting, the latter of which was accompanied by renewed uplift. The Fort Lowell Formation accumulated during the Quaternary development of modern through-flowing the maturation of the drainage. The composite Cenozoic stratigraphic section of the Tucson basin is at least 20,000 ft thick. The steeply tilted to flat-lying section is composed of indurated to unconsolidated clastic sediments, evaporites, and volcanic rocks that are lithologically and structurally complex. The lithology and structures of the section was greatly affected by the uplift and exhumation of adjacent metamorphic core-complex rocks. Similar Cenozoic geologic relations have been identified in other parts of southern Arizona.

This map shows only those earthquakes with epicenters located within the boundaries of Ohio, even though earthquakes in nearby states or countries may have been felt or may have caused damage in Ohio.
\nThe data in table 1 were used to compile the seismicity map; these data are a corrected, expanded, and updated (through 1983) version of the data used by Algermissen (1969) for a study of seismic risk in the United States. The locations and intensities of some earthquakes were revised and intensities were assigned where none had been before. Many earthquakes were added to the original list from new data sources as well as from some old data sources that had not been previously used. The data in table 1 represent best estimates of the location of the epicenter, magnitude, and intensity of each earthquake on the basis of historical and current information. Some of the aftershocks from large earthquakes are listed, but not all, especially for earthquakes that occurred before seismic instruments were universally used.
\nThe latitude and longitude coordinates of each epicenter were rounded to the nearest tenth of a degree and sorted so that all identical locations were grouped and counted . These locations are represented on the map by a triangle. The number of earthquakes at each location is shown on the map by the arabic number to the right of the triangle. A Roman numeral to the left of a triangle is the maximum Modified Mercalli intensity (Wood and Neumann, 1931) of all earthquakes at that geographic location. The absence of an intensity value indicates that no intensities have been assigned to earthquakes at that location. The year shown below each triangle is the latest year for which the maximum intensity was recorded.
