In addition, it serves as a user's manual for the authors' mapping system. Procedures were developed which allow commodity specialists to enter deposit information, retrieve selected data, and plot deposit symbols in any geographic area within the conterminous United States. The mapping system uses both micro- and mainframe computers. The microcomputer is used to input and retrieve information, thus minimizing computing charges. The mainframe computer is used to generate map plots which are printed by a Calcomp plotter. \r\n\r\nSelector V data base system is employed for input and retrieval on the microcomputer. A general mapping program (Genmap) was written in FORTRAN for use on the mainframe computer. Genmap can plot fifteen symbol types (for point locations) in three sizes. The user can assign symbol types to data items interactively. Individual map symbols can be labeled with a number or the deposit name.

This report describes a plan of study for a water-resource assessment of the Sangamon River basin in central Illinois. The purpose of the study would be to provide information to basin planners and regulators on the quantity, quality, and use of water to guide management decisions regarding basin development. Water quality and quantity problems in the Sangamon River basin are associated primarily with agricultural and urban activities, which have contributed high concentrations of suspended sediment, nitrogen, phosphorus, and organic matter to the streams. The impact has resulted in eutrophic lakes, diminished capacity of lakes to store water, low concentrations of dissolved oxygen, and turbid stream and lake waters. The four elements of the plan of study include: (1) determining suspended sediment and nutrient transport, (2) determining the distribution of selected inorganic and organic residues in streambed sediments, (3) determining the waste-load assimilative capacity of the Sangamon River, and (4) applying a hydraulic model to high streamflows.

The central part of the province is occupied by the Tatar arch, which contains the major share of the oil fields of the province. The Perm-Bashkir arch forms the northeastern part of the regional high, and the Zhigulevsko-Orenburg arch makes up the southern part. These arches are separated from one another by elongate downwarps. \r\n\r\nThe platform cover overlies an Archean crystalline basement and consists of seven main sedimentation cycles as follows: 1) Riphean (lower Bavly) continental sandstone, shale, and conglomerate beds from 500 to 5,000 m thick deposited in aulacogens. 2) Vendian (upper Bavly) continental and marine shale and sandstone up to 3,000 m thick. 3) Middle Devonian-Tournaisian transgressive deposits, which are sandstone, siltstone, and shale in the lower part and carbonates with abundant reefs in the upper; thickness is 300-1,000 m. In the upper carbonate part is the Kamsko-Kinel trough system, which consists of narrow interconnected deep-water troughs. 4) The Visean-Namurian-Bashkirian cycle, which began with deposition of Visean clastics that draped over reefs of the previous cycle and filled in an erosional relief that had formed in some places on the sediments of the previous cycle. The Visean clastics are overlain by marine carbonates. Thickness of the cycle is 50-800 m. 5) Early Moscovian-Early Permian terrigenous clastic deposits and marine carbonate beds 1,000-3,000 m thick. 6) The late Early Permian-Late Permian cycle, which reflects maximum growth of the Ural Mountains and associated Ural foredeep. Evaporites were first deposited, then marine limestones and dolomites, which intertongue eastward with clastic sediments from the Ural Mountains. 7) Continental redbeds of Triassic age and mixed continental and marine elastic beds of Jurassic and Cretaceous age, which were deposited on the southern, southwestern, and northern margins of the Russian platform; they are generally absent in the Volga-Ural province, however. \r\n\r\nThe Volga-Ural oil and gas basin is a single artesian system that contains seven aquifers separated by seals. The areas of greatest hydraulic head are in the eastern parts of the basin near areas where the aquifers crop out on the western slopes of the Ural Mountains. The Peri-Caspian basin is the principal drainage area of the artesian system. \r\n\r\nApproximately 600 oil and gas fields and 2,000 pools have been found in the Volga-Ural province. Nine productive sequences are recognized as follows: 1) Upper Proterozoic (Bavly beds), which are promising but not yet commercial. 2) Clastic Devonian, which contains the major reserves and includes the main pays of the super-giant Romashkino field. 3) Carbonate Upper Devonian and lowermost Carboniferous, which is one of the main reef-bearing intervals. 4) Visean (Lower Carboniferous) elastics, which are the main pays in the super-giant Arian field. 5) Carbonate Lower and Middle Carboniferous. 6) Clastic Middle Carboniferous Moscovian. 7) Carbonate Middle and Upper Carboniferous. 8) Carbonate-evaporite Lower Permian, which contains the major gas reserves and the lower part of the Melekess tar deposits. 9) Clastic-carbonate Upper Permian, which contains the major part of the Melekess tar deposits.\r\n\r\nThe Volga-Ural province is divided into several productive regions on a basis of differences in structure, distribution of reservoir and source-rock facies, and general composition of the petroleum accumulations. These regions are the Tatar arch, Birsk saddle, Upper Kama depression, Perm-Bashkir arch, Ufa-Orenburg monocline, Melekess-Sernovodsko-Abdulino basin, Zhligulevsko-Orenburg arch, Ural foredeep, and north borders of the Peri-Casplan depression. \r\n\r\nExploration activity has declined in recent years; however, interest remains high in several parts of the province, particula","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr83711","usgsCitation":"Peterson, J.A., and Clarke, J.W., 1983, Geology of the Volga-Ural petroleum province and detailed description of the Ramashkino and Arlan oil fields: U.S. Geological Survey Open-File Report 83-711, vii, 175 p. ill., maps ;28 cm., https://doi.org/10.3133/ofr83711.","productDescription":"vii, 175 p. ill., maps ;28 cm.","costCenters":[],"links":[{"id":143606,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1983/0711/report-thumb.jpg"},{"id":38498,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1983/0711/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ac9e4b07f02db67c9b7","contributors":{"authors":[{"text":"Peterson, James A.","contributorId":106872,"corporation":false,"usgs":true,"family":"Peterson","given":"James","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":161780,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Clarke, James W.","contributorId":35297,"corporation":false,"usgs":true,"family":"Clarke","given":"James","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":161779,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Systematic Crone electromagnetic and self-potential surveys indicate that weakly conductive tabular bodies having a weak to moderate self-potential effect extend downdip from two discontinuously exposed, parallel ridges of mineralized quartzite. Crone electromagnetic data were quantitatively interpreted using characteristic parameter lines adapted for use at 1830 and 5010 Hz, the frequencies employed at Umm ar Rummf. Depths to the top of the conductors were computed to be from 20 to 40 m or about the thickness of the oxidized zone, which behaves as a variably conductive overburden. Both tabular conductors can also be traced geophysically to the north and south of the copper-bearing outcrops. The association of the geophysical anomalies with copper-mineralized rocks has been proved by drilling. \r\n\r\nReconnaissance MAXMIN electromagnetic profiles across the target using a wide coil separation show broad, low-amplitude anomalies that may indicate mineralized rocks at depth, and reconnaissance ground-magnetic profiles show strong total-field intensity anomalies associated with basaltic dikes of probable Tertiary age.

High aeroradioactivity is associated with potassium-rich granitic plutons, muscovite-rich gneisses, schists, and metavolcanic rocks; positive gravity and magnetic anomalies are associated with gabbro plutons; and negative gravity anomalies are associated with granitic plutons. \r\n\r\nAt the west side of the slate belt, the Tillery phyllite is interpreted as having undergone progressive metamorphism. The underlying Uwharrie Formation extends into the Charlotte belt where it is mapped as metavolcanic rocks. Gravity models of the Carolina slate belt indicate that it is a synform containing a wedge of metasedimentary and volcanoclastic rock on plutonic basement. The basement is exposed in the adjacent Charlotte belt antiform. \r\n\r\nThe northern Charlotte belt contains mainly plutonic rocks which have been divided into 3 supergroups of plutons based upon chemistry, mineralogy, texture, and age. They are: \r\n\r\n1. Old Plutonic supergroup - plutons 545-490 m.y. that are medium to coarse-grained tonalite, quartz diorite, and granodiorites. \r\n\r\n2. Concord-Salisbury supergroup -- plutons 426-350 m.y. which form sheet-like intrusions of differentiated gabbro; local volcanic centers with ring complexes 13 km in diameter that suggest magma chambers 0 - 8 km deep; smaller bodies of diorite, monzonite, and syenite; and small Salisbury type granodiorites. \r\n\r\n3. Landis supergroup -- plutons 350-280 m.y. that are usually very coarse-grained, porphyritic, 'big feldspar,' potassium-rich granites. \r\n\r\nThe Mecklenburg-Weddington gabbro complex of the Concord-Salisbury supergroup, the largest feature in the study area, contains three large gabbro plutons. The gabbro intruded old Plutonic complex rocks and could-have produced the metamorphic reaction K-feldspar + sillimanite quartz + muscovite reflected in the mineral assemblage of adjacent felsic metavolcanic rocks. Gravity models indicate a lopolith 3.5- to 4.5-km thick with a 2 km sill extending to the northeast. Positive magnetic and gravity anomalies suggest the lopolith is. connected with the Concord gabbro complex to the northeast. \r\n\r\nThe sheet-like intrusions of Concord-Salisbury group gabbros, forming the core of the composite 5atholith, have medium-grained Salisbury type granodiorite above, and coarser-grained Landis granite below. The position of the supergroups as presently exposed may be a function of level of erosion versus level of emplacement. The plutons in the composite batholith span 200 m.y. according to current age data and are arranged with the oldest at the top and the youngest at the bottom. However, Rb-Sr and K-At ages in the Piedmont are more likely to reflect age of crustal uplift than the age of metamorphism or intrusion.
