In this study, recent ferric oxides, mostly goethites of Holocene age, were collected and analyzed from a variety of modern soil, stream, and marine environments, where formation temperature and the oxygen isotopic composition (␦18O) of the water from which ferric oxides precipitated can be independently measured or estimated. This allows comparison of experimental ␣-T relationships with data from natural systems. Selective dissolution methods were refined for the pretreatment of fine-grained minerals in order to obtain reliable ␦18O values for pure and crystalline ferric oxides. The difference (⌬␦18O) between the ␦18O value of goethite and that of local mean meteoric water ranges from Ϫ1.5 to ϩ6.3‰ for soil goethites from New Jersey, Indiana, Michigan, Iowa, South Dakota, and Taiwan.

I Approved by ~ (advisor) ~lo/ ii ABSTRACT The Maquoketa Formation (Upper Ordovician-Cincinnatian Series) has been extensively studied for over one hundred years, but a petrographic study of its cyclic lithologies has been neglected. The following six distinct Maquoketa lithologies have been recognized in this study in Pike County, Missouri& 1) phosphatic biosparite, 2) phos­ phorite, 3) micrite-microsparite, 4) dolomitic shale, 5) dolomitic marlstone, and 6) dolomitic quartz siltstone. Three cycle types are present in the Maquoketa. They are expressed as thin beds (1-20 inches) of alternating micrite-shale, micrite-marlstone, and shale-siltstone.

Ostrom, Wisconsin Geological Survey, Madison, Wisconsin Peter Sheehan, Milwaukee Public Museum· ISBN :0-89326-016-4 Milwaukee Public Museum Press Published by the Order of the Board of Trustees Milwaukee Public Museum Accepted for publication July, 1980 Stratigraphy and Paleontology of the Maquoketa Group (Upper Ordovician) at Wequiock Creek, Eastern Wisconsin Paul A. 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.
