Early sediments of Middle Cambrian and sub-Mt. Simon (Lamotte) deposition are found in the grabens, but do not crop out in the area. Growth faulting continued to deepen the Rough Creek Graben and possibly the Reelfoot Rift during much of the Paleozoic interval. Renewed tectonic activity, probably occurring during the Mesozoic Era, uplifted the Pascola Arch near the center of the Reelfoot Rift and also renewed uplift of many structural features and fault zones, some of which were displaced in a direction opposite to earlier movements. Erosion then removed thousands of feet of sediment from the area, and beveled the PascolaArch. Igneous plutons were injected into the Precambrian basement rocks and some penetrated into the sedimentary section and formed dikes and sills. Subsidence followed with the formation of the Missis- sippi Embayment where Cretaceous and Tertiary sediments collected and buried the Pascola Arch. The area remains seismically active to the present day. ii CONTENTS Page ABSTRACT...............................ii LIST OF FIGURES .................. .......................... .. iv APPENDIX .................. ............. ................... v TABLE ................................................... ......... v INTRODUCTION ................... ............................

B. WILLMAN AND J. NORMAN PAYNE Illinois State Geological Survey ABSTRACT A nearly complete sequence of Ordovician strata along Fox River, southwest of Aurora, indicates the presence of the Kankakee arch—a major structure trending northwest-southeast across northeastern Illinois —and the probable location of the Sandwich fault, which parallels the arch for many miles and had been found previously by studies of well records. Outcrops of sandstone and dolomite which have long been corre- lated with the St. Peter and Galena-Platteville formations have been found to belong to the New Richmond sandstone and the Shakopee dolomite. Study of the outcrops and well records shows that the anticlinal struc- ture underwent major movements both before and after deposition of the St. Peter sandstone. INTRODUCTION subsurface data showed that this struc- ture, termed the "Kankakee arch," In the earliest geological studies of this (1) 2 had its greatest deformation before, rather area the sandstone and the dolomite out- than since, St.

    Deep Oil Possibilities of the Illinois Basin

    s Ccc 36? STATE OF ILLINOIS DEPARTMENT OF REGISTRATION AND EDUCATION DEEP OIL POSSIBILITIES OF THE ILLINOIS BASIN Alfred H. Bell Elwood Atherton T. C. Buschbach David H. Swann ILLINOIS STATE GEOLOGICAL SURVEY John C. Frye, Chief URBANA CIRCULAR 368 1964 . DEEP OIL POSSIBILITIES OF THE ILLINOIS BASIN Alfred H. Bell, Elwood Atherton, T. C. Buschbach, and David H. Swann ABSTRACT The Middle Ordovician and younger rocks of the Illinois Basin, which have yielded 3 billion barrels of oil, are underlain by a larger volume of virtually untested Lower Ordovician and Cambrian rocks. Within the region that has supplied 99 percent of the oil, where the top of the Middle Ordovician (Trenton) is more than 1,000 feet be- low sea level, less than 8 inches of hole have been drilled per cubic mile of the older rocks. Even this drilling has been near the edges; and in the central area, which has yielded five- sixths of the oil, only one inch of test hole has been drilled per cubic mile of Lower Ordovician and Cambrian. Yet drilling depths are not excessive, ranging from 6,000 to 14,000 feet to the Precambrian. More production may be found in the Middle Ordovician Galena Limestone (Trenton), thus extending the present productive regions. In addition, new production may be found in narrow, dolomitized fracture zones in the tight limestone facies on the north flank of the basin . The underlying Platteville Limestone is finer grained and offers fewer possibilities. The Joachim Dolomite oil- shows occur in tight sandstone bodies that should have commercial porosity in some re- gions.

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.

    Mineral Resources of the Illinois Basin in the Context of Basin Evolution St. Louis, Missouri, January 22-23,1992 Program and Abstracts Edited by Martin B. Goldhaber and J. James Eidel U.S. Geological Survey Open-File Report 92-1 This report is preliminary and has not been edited or reviewed for conformity with U.S. Geological Survey, Illinois State Geological Survey, Kentucky Geological Survey, Missouri Division of Geology and Land Survey, and Indiana Geological Survey standards. PREFACE The mineral resources of the U.S. midcontinent were instrumental to the development of the U.S. economy. Mineral resources are an important and essential component of the current economy and will continue to play a vital role in the future. Mineral resources provide essential raw materials for the goods consumed by industry and the public. To assess the availability of mineral resources and contribute to the abib'ty to locate and define mineral resources, the U.S. Geological Survey (USGS) has undertaken two programs in cooperation with the State Geological Surveys in the midcontinent region. In 1975, under the Conterminous U.S. Mineral Assessment Program (CUSMAP) work began on the Rolla 1° X 2° Quadrangle at a scale of 1:250,000 and was continued in the adjacent Springfield, Harrison, Joplin, and Paducah quadrangles across southern Missouri, Kansas, Illinois, Arkansas, and Oklahoma. Public meetings were held in 1981 to present results from the Rolla CUSMAP and in 1985 for the Springfield CUSMAP. In 1984, the Midcontinent Strategic and Critical Minerals Project (SCMP) was initiated by the USGS and the State Geological Surveys of 16 states to map and compile data at 1:1,000,000 scale and conduct related topical studies for the area from latitude 36° to 46° N.

Ryan, Governor Department of Natural Resources ILLINOIS STATE GEOLOGICAL SURVEY William W. Shilts, Chief EDITOR'S MESSAGE Greetings from the Executive Committee of the North Central Section of the Geological Society of America! As geologists, we all recognize the great importance of field experiences. This year's meeting includes a diverse and excellent set of field trips. Collectively, this year's field trips visit a broad spectrum of the geologic features of Illinois and Missouri that range in age from Precambrian to Quaternary. These trips present a number of new ideas and interpretations that will broaden the perspectives of all field trip participants. Your participation, interaction, and exchange of ideas with the field trip leaders are encouraged at all times These trips are the culmination of the time and energy freely given by a number of individuals. I would like to thank and recognize the field trip leaders for their hard work in planning the field trips and preparing the individual field guides. I would also like to thank the technical reviewers at Illinois State University and the Illinois State Geological Survey for their efforts. I appreciate the efforts of Jon Goodwin and the publication staff at the Illinois State Geological Survey for their substantial work in preparing this field guide. A special thanks goes out to the property owners who have been most helpful in planning these trips.
