The data were statistically summarized and regression equations were developed to define relationships between water-quality variables. Where applicable, measured water-quality conditions were compared to various water-use standards. Measured concentrations of dissolved solids ranged from 145 to 12,200 milligrams per liter. Concentrations commonly exceeded 1,000 milligrams per liter and thereby present a high to very high salinity hazard for irrigation. Streamflow of the area contains predominantly sodium and sulfate ions and generally constitutes a medium to very high sodium hazard for irrigation during base flow. The water in most streams is generally adequate for livestock consumption during base flow. Concentrations of suspended sediment were extremely variable and had a direct correlation to water discharge. Measured suspended-sediment concentrations ranged from 4 to 23 ,000 milligrams per liter. Sediment-transport curves were developed for 18 of the study sites. Mean annual suspended-sediment loads were determined at five sites using the flow-duration, sediment-transport curve method. Mean annual sediment loads ranged from 1,010 to 72,7000 tons.

It has been prepared to aid and encourage the field-oriented coal scientist to participate directly in petrographic coal-description activities. The objectives and past and current practices of coal description vary widely. These are briefly reviewed and illustrated with examples. Sampling approaches and techniques for collecting columnar samples of fresh coal are also discussed. The recommended procedures and methodology emphasize the fact that obtaining a good megascopic description of a coal bed is much better done in the laboratory with a binocular microscope and under good lighting conditions after the samples have been cut and quickly prepared. For better observation and cross-checking using a petrographic microscope for identification purposes, an in-place polishing procedure (requiring less than 2 min) is routinely used. Methods for using both the petrographic microscope and an automated image analysis system are also included for geologists who have access to such instruments. To describe the material characteristics of a coal bed in terms of microlithotypes or lithotypes, a new nomenclature of (V), (E), (1), (M). (S). (X1). (X2) and so on is used. The microscopic description of the modal composition of a megascopically observed lithologic type is expressed in terms of (VEIM); subscripts are used to denote the volume percentage of each constituent present. To describe a coal-bed profile, semiquantitative data (without microscopic study) and quantitative data (with microscopic study) are presented in ready-to-understand form. The average total composition of any thickness interval or of the entire coal bed can be plotted on a triangular diagram having V, E, and I+ M +S as the apices. The modal composition of any mixed lithologies such as (X1), (X2), and so on can also be plotted on such a triangular ternary diagram. Such diagrams can be used either for tracing compositional variations throughout a single coal-bed profile or for comparing variations between different coal beds.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/cir894","usgsCitation":"Chao, E., Minkin, J., and Thompson, C., 1983, Recommended procedures and methodology of coal description: U.S. Geological Survey Circular 894, iv, 31 p., https://doi.org/10.3133/cir894.","productDescription":"iv, 31 p.","numberOfPages":"36","costCenters":[],"links":[{"id":139148,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/circ/0894/report-thumb.jpg"},{"id":271070,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/circ/0894/report.pdf"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a74e4b07f02db644603","contributors":{"authors":[{"text":"Chao, E.C.","contributorId":47358,"corporation":false,"usgs":true,"family":"Chao","given":"E.C.","email":"","affiliations":[],"preferred":false,"id":148153,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Minkin, J.A.","contributorId":38588,"corporation":false,"usgs":true,"family":"Minkin","given":"J.A.","affiliations":[],"preferred":false,"id":148152,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Thompson, C.L.","contributorId":12189,"corporation":false,"usgs":true,"family":"Thompson","given":"C.L.","email":"","affiliations":[],"preferred":false,"id":148151,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":4698,"text":"twri03A14 - 1983 - Use of flumes in measuring discharge","interactions":[],"lastModifiedDate":"2012-02-02T00:05:31","indexId":"twri03A14","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1983","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":336,"text":"Techniques of Water-Resources Investigations","code":"TWRI","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"03-A14","title":"Use of flumes in measuring discharge","docAbstract":"Flumes for measuring discharge are usually of two general groups-critical-flow flumes and supercritical-flow flumes.

Colluvial purple, red, and pink garnets are dominantly Mg- and Cr-rich, indicating their derivation From peridotites or megacrysts, and have CaO and Cr2O3 contents that fall in the lherzolite trend.
Temperatures were calculated by the Lindsley-Dixon 20 kb method for lherzolites and by the O'Neill-Wood method for harzburgites and dunites, and pressures were calculated by the MacGregor method, or were assumed to be 50 kb for dunites. Most peridotites equilibrated at 1220-1350°C and 50-60 kb, well above a 44mW/m2 shield geotherm and on or at higher P than the graphite-diamond boundary. Four lherzolites are low T-P (830-990°C, 23-42 kb) and are close to the shield geotherm. All four low T-P lherzolites have coarse textures whereas the high T-P cluster has both coarse and porphyroclastic textures, indicating a range of conditions of deformation and recrystallization in a restricted high T-P range. The tiny size (0.01-0.2 mm) of granulated and euhedral olivines in several xenoliths shows that deformation was occurring just prior to incorporation in kimberlite and that ascent was rapid enough (40-70 km/hr) to retard Further coarsening of fine-grained olivine. For other high T-P peridotites, cessation of deformation and beginning of recrystallization before or during inclusion in kimberlite is suggested by larger (up to 3mm) euhedral olivines in a matrix of fine granulated olivine or by optical continuity of large and nearby small olivines.
Two low T-P lherzolites contain distinctive, phlogopite-rimmed, 5-8mm clots of moderate-Cr garnet + Cr-spinel + Cr-diopside + enstatite that are inferred to have formed by reaction of an initial high-Cr garnet brought into the garnet + spinel stability Field. This suggests a reduction in pressure and temperature prior to inclusion in the kimberlite, followed by metasomatic introduction of phlogopite. These textural and compositional variations of peridotites seem most compatible with kimberlite generation and ascent during dynamic diapiric perturbation of the upper mantle.

The most important factors affecting surface-water quality and streamflow during the period of the study were wastewater discharges, their abatement beginning in 1975, and the drought during 1976 and 1977. Substantial decreases in fecal-coliform bacteria and nutrients occurred from 1975 through 1978, corresponding to regulations specifying no discharge of wastewater during the lowflow season. Generally, turbidity and nutrients were least during the 1977 lowflow season. However, specific conductance increased markedly during 1976 and 1977 in response to substantially decreased streamflow during the drought. Algal growth in the Russian River depends on the amount of nitrogen in the water and is not limited by the amount of phosphorus in the water. Cold water releases from Lake Mendocino seem to be important for maintaining downstream water temperatures at acceptable levels for survival of certain aquatic organisms, retarding aquatic community respiration, and preventing nuisance growths of photoplankton and periphyton. During August 1977, a diel study showed the Russian River was a heterotrophic system where photosynthetic production of oxygen was not sufficient to offset respiration.

Most of the water infiltrated into the permeable alluvial deposits along the Sal and Gila Rivers and increased the amount of ground water in storage.

The operating procedures for each type of test are designed to independently lead a first-time user through the various stages of using the computer to control the test. \r\n\r\nContinuing advances in computer technology and the availability of desktop microcomputers with a wide variety of peripheral equipment at a reasonable cost can create an efficient automated geotechnical testing environment. A geotechnical testing environment is shown in figure 1. Using an automatic data acquisition system, laboratory test data from a variety of sensors can be collected, and manually or automatically recorded on a magnetic device at the same apparent time. The responses of a test can be displayed graphically on a CRT in a matter of seconds, giving the investigator an opportunity to evaluate the test data, and to make timely, informed decisions on such matters as whether to continue testing, abandon a test, or modify procedures. Data can be retrieved and results reported in tabular form, or graphic plots, suitable for publication. \r\n\r\nThermistors, thermocouples, load cells, pressure transducers, and linear variable differential transformers are typical sensors which are incorporated in automated systems. The geotechnical tests which are most practical to automate are the long-term tests which often require readings to be recorded outside normal work hours and on weekends. Automation applications include incremental load consolidation tests, constant-rate-of-strain consolidation tests, direct shear tests, ring shear tests, and triaxial shear tests.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83491","usgsCitation":"Powers, P.S., 1983, A microcomputer-based data acquisition and control system for the direct shear, ring shear, triaxial shear, and consolidation tests: U.S. Geological Survey Open-File Report 83-491, vi, 88 p. ill. ;28 cm., https://doi.org/10.3133/ofr83491.","productDescription":"vi, 88 p. ill. ;28 cm.","costCenters":[],"links":[{"id":143347,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0491/report-thumb.jpg"},{"id":38548,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0491/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b23e4b07f02db6adff4","contributors":{"authors":[{"text":"Powers, Philip S.","contributorId":102078,"corporation":false,"usgs":true,"family":"Powers","given":"Philip","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":161888,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":63507,"text":"gp952 - 1983 - Bouguer gravity map of the western arm of the Black Rock Desert, northwestern Nevada","interactions":[],"lastModifiedDate":"2025-07-17T21:30:17.320638","indexId":"gp952","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1983","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":317,"text":"Geophysical Investigations Map","code":"GP","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"952","title":"Bouguer gravity map of the western arm of the Black Rock Desert, northwestern Nevada","docAbstract":"No abstract available.

Recharge occurs largely from local precipitation, although small quantities of potable ground water from outside areas also recharge these aquifers. Water levels in the Pajaro and Salinas River valleys north and south of the study area are lower than most of the intervening area, and recharge from the east is blocked by faults and impervious rock. Ocean water moves in from the west to replace depleted freshwater storage in the upper part of the Aromas Sand, alluvium, and terrace deposits. The North County area was divided into subareas to estimate pumpage demands and to evaluate ground-water yields. Pumpage near the granitic ridge, an area of limited storage, nearly matches local recharge. West of the granitic ridge, pumpage exceeds available recharge but draws upon a large storage potential. Deeper units than those now tapped by wells in the Aromas Sand and the underlying Purisima Formation may have substantial water-bearing potential for additional ground-water development. Extensive development of water from these formations might be limited, however, by the remoteness of the recharge source and by the proximity to the ocean.

This report includes a table of monthly flows at these sites from 1930-79. Computations were based on records from the 1930-79 water years. Daily net inflow estimates (lake inflow minus evaporation and possible groundwater seepage) were computed from the outflows and changes in lake storage. Lake storage was estimated from lake level data and elevation-capacity curves for each lake. A smoothing technique was applied to plots of daily lake levels before net inflows were computed. Where lake level or outflow data were missing, net flows were estimated from linear regression equations. Analysis of results indicates that: (1) smoothing the plots of daily lake levels significantly reduces random fluctuations resulting from seiche or wind action; (2) continuous lake storage recorders provide a more reliable record than staff gages (once-daily, lake level readings) for computing daily changes in lake storage; and (3) the effect of smoothing decreases as the computational period is increased.

The ground area portrayed in each diagram is equal; the south edge of the Mount St. Helens drawing is lower than that of Crater Lake drawing because elevations drop away toward the south, whereas elevations are more constant at the north and south edges of the Crater Lake diagram.

The ability of a source rock to generate oil and gas is directly related to its kerogen content and thermal maturity; hence, thermal maturity is commonly used as an exploration tool. This publication consists of two parts: a coal rank map for the basinwide Cameo and Fairfield or equivalent coal zone and three cross sections showing the variation in a coal rank for the entire Mesaverde. Structure contours on the map show the top of the Rollins Sandstone Member of the Mesaverde Formation and its equivalent the Trout Creek Sandstone Member of the Iles Formation of the Mesaverde Group, which immediately underlie the Cameo and Fairfield zone. The structure contours show the fairly strong correlation between structure and coal rank in the basin, suggesting that maximum overburden was the key factor in determining the coal ranks. Even in the southern part of the basin where extensive plutonism occurred during the Oligocene, coal ranks still generally follow structure; indicating that the plutons had little affect on the coals. On the cross sections both the top of the Rollins and Trout Creek, and the top of the Mesaverde Formation/Group are shown. A complete analysis of the entire Mesaverde in the basin would require more information than is presently available.
