STATE OF ILLINOIS c a WILLIAM G. STRATTON, Governor DEPARTMENT OF REGISTRATION AND EDUCATION VERA M. BINKS, Director PETROGRAPHY AND ORIGIN OF ILLINOIS NODULAR CHERTS Donald L. Biggs DIVISION OF THE ILLINOIS STATE GEOLOGICAL SURVEY JOHN C. 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.

  • Thermal Expansion of Certain Illinois Limestones and Dolomites

Frye, Chief URBANA CIRCULAR 415 1967 THERMAL EXPANSION OF CERTAIN ILLINOIS LIMESTONES AND DOLOMITES Richard D. Harvey ABSTRACT Thermal expansion is an important property of lime- stones that affects their utilization as building stone and possibly as aggregates in concrete. Thermal expansion curves were obtained on 82 essentially pure calcitic speci- mens taken from 21 different Illinois limestones and on 62 Il- linois dolomites and dolomitic limestone specimens taken from 18 different samples. The specimens were 1 inch in di- ameter and 4 inches long. Their expansion was measured dry, with a vitreous silica dilatometer, over a temperature range of -4 to 17 6° F. The average of the mean expansion coefficient of limestones in the interval -4 to 68° F. is 1.9x 6 10- 6/°F.; in the interval 68 to 176° F. it is 4.5 x lO" /" F. The corresponding coefficients of the dolomites are 4.3 x 10" 6/ F. and 5.5 x 10" 6/° F. The data indicate that the texture of the rock affects the thermal expansion behavior of limestones and dolomites that has not heretofore been noted. Most striking is an ob- servation that coarse-grained limestones and, to some ex- tent, coarse-grained dolomites expand at a significantly low- er rate below 40° F.

Pentamerid brachiopods are rare in the Wenlock-age Canberra Formation, but re-examination of old collections held by Geoscience Australia revealed the presence of four recognisable taxa, described here. The gypiduline Ascanigypa glabra (Mitchell) was originally described from Yass, northwest of Canberra, and has since been recorded from areas farther south; the latter records are revised. The pentamerides are Apopentamerus clarkei Strusz, Kirkidium (Kirkidium) canberrense sp. nov., and Rhipidium (Pararhipidium) oepiki sp. nov.

    An early Silurian (Aeronian) cephalopod fauna from Kopet-Dagh, north-eastern Iran: including the earliest records of non-orthocerid cephalopods from the Silurian of Northern Gondwana DAVID H. EVANS, MANSOUREH GHOBADI POUR, LEONID E. POPOV & HADI JAHANGIR The cephalopod fauna from the Aeronian Qarebil Limestone of north-eastern Iran comprises the first comprehensive re- cord of early Silurian cephalopods from peri-Gondwana. Although consisting of relatively few taxa, the assemblage in- cludes members of the orders Oncocerida, Discosorida, Barrandeocerida and Orthocerida. Coeval records of several of these taxa are from low palaeolatitude locations that include Laurentia, Siberia, Baltica and Avalonia, and are otherwise unknown from peri-Gondwana until later in the Silurian. The cephalopod assemblage occurs in cephalopod limestones that currently represent the oldest record of such limestones in the Silurian of the peri-Gondwana margin. The appear- ance of these cephalopods, together with the development of cephalopod limestones may be attributed to the relatively low latitudinal position of central Iran and Kopet-Dagh compared with that of the west Mediterranean sector during the Aeronian. This, combined with the continued post-glacial warming after the Hirnantian glaciation, facilitated the initia- tion of carbonate deposition and conditions suitable for the development of the cephalopod limestones whilst permitting the migration of cephalopod taxa, many of which were previously restricted to lower latitudes. • Key words: Llandovery, Aeronian, Cephalopoda, palaebiogeography, peri-Gondwana.

Gruenwald2 1 Repsol Exploración, Paseo de la Castellana 280, 28046 Madrid, Spain. [email protected] 2 REMSA, Dhat El-Imad Complex, Tower 3, Floor 9, Tripoli, Libya. Keywords: Ordovician, Libya, glaciation, Mamuniyat, Melaz Shugran, Hirnantian. INTRODUCTION An Upper Ordovician glacial episode is widely recognized as a significant event in the geological history of the Lower Paleozoic. This is especially so in the case of the Saharan Platform where Upper Ordovician sediments are well developed and represent a major target for hydrocarbon exploration. This paper is a brief summary of the results of fieldwork, in outcrops across SW Libya, together with the analysis of cores, hundreds of well logs (including many high quality image logs) and seismic lines focused on the uppermost Ordovician of the Murzuq Basin. STRATIGRAPHIC FRAMEWORK The uppermost Ordovician section is the youngest of three major sequences recognized widely across the entire Saharan Platform: Sequence CO1: Unconformably overlies the Precambrian or Infracambrian basement. It comprises the possible Upper Cambrian to Lowermost Ordovician Hassaouna Formation. Sequence CO2: Truncates CO1 along a low angle, Type II unconformity. It comprises the laterally extensive and distinctive Lower Ordovician (Tremadocian-Floian?) Achebayat Formation overlain, along a probable transgressive surface of erosion, by interbedded burrowed sandstones, cross-bedded channel-fill sandstones and mudstones of Middle Ordovician age (Dapingian-Sandbian), known as the Hawaz Formation, and interpreted as shallow-marine sediments deposited within a megaestuary or gulf.

    HKT *£ir «cT 4»BBb %* Alft Phylogenetic Relationships of the Earliest Anisostrophically Coiled Gastropods SERIES PUBLICATIONS OF THE SMITHSONIAN INSTITUTION Emphasis upon publication as a means of "diffusing knowledge" was expressed by the first Secretary of the Smithsonian. In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Contributions to Anthropology Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to the Marine Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Folklife Studies Smithsonian Studies in Air and Space Smithsonian Studies in History and Technology In these series, the Institution publishes small papers and full-scale monographs that report the research and collections of its various museums and bureaux or of professional colleagues in the world of science and scholarship. The publications are distributed by mailing lists to libraries, universities, and similar institutions throughout the world. Papers or monographs submitted for series publication are received by the Smithsonian Institution Press, subject to its own review for format and style, only through departments of the various Smithsonian museums or bureaux, where the manuscripts are given substantive review.
