Geology and Oil Production in the Tuscola Area, Illinois

M. Bristol and Ronald Prescott ABSTRACT The Tuscola Anticline, in east-central Illinois, lies astride the complex LaSalle Anticlinal Belt and dips steeply westward into the Fairfield Basin and gradually eastward into the Murdock Syncline. The anticline is broken into two structural highs, the Hayes Dome and the Shaw Dome. Pleistocene sediments, 50 to 250 feet thick, cover the area. Pennsylvanian sediments cover much of the area, thinning to expose an inlier of Mississippian, Devonian, and Silurian rock north of Tuscola. The basal Cambrian for- mation, the Mt. Simon Sandstone, is penetrated by only two wells. Oil production from the Kimmswick (Trenton) com- menced in 1962 from the R. D. Ernest No. 1 Schweighart well, near Hayes, and as of January 1, 1968, approximately 30 wells were producing oil. Cumulative oil production as of January 1, 1968, is approximately 94,000 barrels. The potential pay zone is confined to the upper 5 to 100 feet of structure and to the upper 125 feet of the Kimmswick, whose permeability ranges from 0.1 to 2. millidarcys, av- eraging 0.6, and whose porosity ranges from 2 to 12 per- cent. -

Sivon Department of Geology University of Illinois Urbana, Illinois Abstract: The Maquoketa Group (Upper Ordovician) is poorly exposed in eastern Wisconsin. The most extensive exposure is found along Wequiock Creek, about 10 kilometers north of Green Bay. There the selection includes a small part of the upper Scales Shale and good exposures of the Fort Atkinson Limestone and Brainard Shale. The exposed Scales Shale is 2.4 m of clay, uniform in appearance and containing no apparent fossils. Limestone and dolomite dominate the 3.9 m thick Fort Atkinson Limestone. The carbonate beds alternate with layers of dolomitic shale that contain little to no fauna. The shales represent times of peak terrigenous clastic deposition in a quiet water environment. The car- bonates are predominantly biogenic dolomite and biomicrite. Biotic succession within single carbonate beds includes replacement of a strophomenid-Lepidocyclus dominated bottom community by a trep- ostome bryozoan-Plaesiomys-Lepidocyclus dominated community. Transported echinoderm and cryptostome bryozoan biocalcarenites are common. -

Grand Tower Limestone (Devonian) of Southern Illinois

STATE OF ILLINOIS DEPARTMENT OF REGISTRATION AND EDUCATION GRAND TOWER LIMESTONE (DEVONIAN) OF SOUTHERN ILLINOIS Wayne F. Meents David H. Swann ILLINOIS STATE GEOLOGICAL SURVEY John C. Frye, Chief URBANA CIRCULAR 389 1965 Digitized by the Internet Archive in 2012 with funding from University of Illinois Urbana-Champaign http://archive.org/details/grandtowerlimest389meen GRAND TOWER LIMESTONE (DEVONIAN) OF SOUTHERN ILLINOIS Wayne F. Meents and David H. Swann ABSTRACT The Grand Tower Limestone has been the source of over a hundred million barrels of oil in Illinois, the bulk of the Devo- nian production of the state. The formation underlies most of southern and central Illinois and extends into Missouri, Iowa, Indiana, and Kentucky, where its equivalents are the Cooper, Wapsipinicon, and Jeffersonville Limestones. The Grand Tower has a maximum thickness of a little more than 200 feet. It is a sandy, but otherwise pure, carbonate unit that forms approxi- mately the lower half of the Middle Devonian carbonate sequence of the region. TheGrand Tower is dominantly fossiliferous lime- stone in southern Illinois, dolomite in most of central Illinois, and lithographic limestone where it pinches out in north-central Illinois against the Sangamon Arch. The Sangamon Arch was an east-west structure that probably separated the Grand Tower from the Wapsipinicon Limestone of northern Illinois and Iowa during their deposition. Ithasbeen so modified by post-Devonian move- ments that it is no longer an important structural element. -
Synoptic Taxonomy of Major Fossil Groups
APPENDIX Synoptic Taxonomy of Major Fossil Groups Important fossil taxa are listed down to the lowest practical taxonomic level; in most cases, this will be the ordinal or subordinallevel. Abbreviated stratigraphic units in parentheses (e.g., UCamb-Ree) indicate maximum range known for the group; units followed by question marks are isolated occurrences followed generally by an interval with no known representatives. Taxa with ranges to "Ree" are extant. Data are extracted principally from Harland et al. (1967), Moore et al. (1956 et seq.), Sepkoski (1982), Romer (1966), Colbert (1980), Moy-Thomas and Miles (1971), Taylor (1981), and Brasier (1980). KINGDOM MONERA Class Ciliata (cont.)

Although many extinct classes of molluscs have been proposed, the generally accepted ones are Hyolitha (Marek, 1963), Mattheva (Yochclson, 1966), Stenothecoida (Yochelson, 1969), and Rostroconchia (Pojeta et al., 1972).
