Kolata T. C. Buschbach Janis D. Treworgy ABSTRACT The Sandwich Fault Zone extends northwesterly from near Manhattan, Will County, to near Oregon, Ogle County, a distance of about 85 miles. Drilling samples from explor- atory borings and water wells, drillers' logs, geophysical logs, refraction seismography, earth resistivity profiles, and outcrop studies indicate that the fault zone is about one- half to two miles wide and is upthrown to the south throughout most of its extent. The fault zone has a max- imum cumulative displacement of about 800 feet at its midpoint in southeastern De Kalb County. At the eastern end, in Will County, the fault zone is downthrown to the south with a total displacement of about 150 feet. High-angle faults that commonly bound small grabens and horsts characterize the Sandwich Fault Zone. The Ashton Arch, Oregon Anticline, and many small flexures and faults are closely associated with the fault zone and appear to be genetically related to it. The faulting is post- Niagaran (middle Silurian), pre-lllinoian (Pleistocene) in age. Geologic relationships suggest that the major move- ments were contemporaneous with the deformation of the La Salle Anticlinal Belt in late Paleozoic time.

FRYE, Chief URBANA CIRCULAR 245 1957 ILLINOIS GEOLOGICAL SURVEY LIBRARY JAN 9 1958 ILLINOIS STATE GEOLOGICAL SURVEY 3 3051 00004 4572 PETROGRAPHY AND ORIGIN OF ILLINOIS NODULAR CHERTS Donald L. Biggs ABSTRACT Seventy-eight samples of nodular chert from 18 Illinois lime- stone and dolomite formations, ranging from Cambrian through Mississippian age, were investigated todetermine the petrography and mode of origin of the nodules. Regardless of geologic age or type of host rock, the nodules were similar in mode of occurrence and in principal textural characteristics. The cherts are dominantly microcrystalline or cryptocrys- talline quartz with a lesser amount of fibrous quartz. No opal or hydrated silica was detected. Almost all the cherts contain re- sidual masses of their host rock. Field relationships and a varie- ty of evidence for replacement leads to the conclusion that the cherts are epigenetic concretions formed by metasomatic proc- esses operating during diagenesis and involving the aggregation of silica that originally had been deposited syngenetically with, and dispersed through, the host rocks. INTRODUCTION Chert is found in many limestones that crop out in Illinois and range in age from Cambrian to Mississippian. The chert may appear as nodules, len- ses, or beds, and some Devonian rocks in extreme southern Illinois are entire- ly chert.

Lethaia,Vol.44, pp. 185–202. Recent revisions to the biostratigraphic and chronostratigraphic assignment of strata from the type area of the Niagaran Provincial Series (a regional chronostratigraphic unit) have demonstrated the need to revise the chronostratigraphic correlation of the Silurian System of North America. Recently, the working group to restudy the base of the Wen- lock Series has developed an extremely high-resolution global chronostratigraphy for the Telychian and Sheinwoodian stages by integrating graptolite and conodont biostratigra- 13 phy with carbonate carbon isotope (d Ccarb) chemostratigraphy. This improved global chronostratigraphy has required such significant chronostratigraphic revisions to the North American succession that much of the Silurian System in North America is cur- rently in a state of flux and needs further refinement. This report serves as an update of the progress on recalibrating the global chronostratigraphic correlation of North Ameri- can Provincial Series and Stage boundaries in their type area.

  • Strophomenide and Orthotetide Silurian Brachiopods from the Baltic Region, with Particular Reference to Lithuanian Boreholes
    Strophomenide and orthotetide Silurian brachiopods from the Baltic region, with particular reference to Lithuanian boreholes PETRAS MUSTEIKIS and L. ROBIN M. COCKS Musteikis, P. and Cocks, L.R.M. 2004. Strophomenide and orthotetide Silurian brachiopods from the Baltic region, with particular reference to Lithuanian boreholes. Acta Palaeontologica Polonica 49 (3): 455–482. Epeiric seas covered the east and west parts of the old craton of Baltica in the Silurian and brachiopods formed a major part of the benthic macrofauna throughout Silurian times (Llandovery to Pridoli). The orders Strophomenida and Orthotetida are conspicuous components of the brachiopod fauna, and thus the genera and species of the superfamilies Plec− tambonitoidea, Strophomenoidea, and Chilidiopsoidea, which occur in the Silurian of Baltica are reviewed and reidentified in turn, and their individual distributions are assessed within the numerous boreholes of the East Baltic, particularly Lithua− nia, and attributed to benthic assemblages. The commonest plectambonitoids are Eoplectodonta(Eoplectodonta)(6spe− cies), Leangella (2 species), and Jonesea (2 species); rarer forms include Aegiria and Eoplectodonta (Ygerodiscus), for which the new species E. (Y.) bella is erected from the Lithuanian Wenlock. Eight strophomenoid families occur; the rare Leptaenoideidae only in Gotland (Leptaenoidea, Liljevallia). Strophomenidae are represented by Katastrophomena (4 spe− cies), and Pentlandina (2 species); Bellimurina (Cyphomenoidea) is only from Oslo and Gotland. Rafinesquinidae include widespread Leptaena (at least 11 species) and Lepidoleptaena (2 species) with Scamnomena and Crassitestella known only from Gotland and Oslo. In the Amphistrophiidae Amphistrophia is widespread, and Eoamphistrophia, Eocymostrophia, and Mesodouvillina are rare. In the Leptostrophiidae Mesoleptostrophia, Brachyprion,andProtomegastrophia are com− mon, but Eomegastrophia, Eostropheodonta, Erinostrophia,andPalaeoleptostrophia are only recorded from the west in the Baltica Silurian.

  • 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.

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.
