. Oolites in the Green River Formation of Central Utah, and the Problem of Oolite Growth Stuart L. Schoff, DePauw University Oolitic limestone occurs in the Green River formation, of Eocene age, at Manti, in central Utah. A microscopic study of thin sections of the rock suggests conditions under which the oolite originated. As described by Bradley (1), and others, the Green River formation was deposited in a great fresh-water lake, or several lakes—an environ- ment contrasting strongly with the highly saline environment of Great Salt Lake, where oolitic grains are now forming, and less strongly with the marine conditions under which many oolites of the geologic column probably originated. Description.—The oolites are composed of calcium carbonate, chiefly as calcite, with an admixture of silt. Some of the material has been recrystallized, and some is now silicified. The average diameter of the grains is between 0.4 and 0.5 mm. They are circular in cross-section, elongate or oval, triangular, and irregular. In general, the outline con- forms with the shape of the nucleus, if one is present, but there are grains in which the outer zones are eccentric (Fig. 1, A) Uncommonly the oolitic grains contain mineral fragments as nuclei, but, even under high magnification, the centers of most of the grains appear simply as structureless spherical bodies of the same material as the rest of the grain. Hence the nuclei suggest little as regards causes for precipitation of calcium carbonate. Figure 1, B and Figure 2 illustrate grains with two centers of growth. One grain with three centers was noted. -

The present estimate of the average subsidence rate for the last 54 million years is Leg 20 recovered the first oolite drilled during the Deep 32 BuB (32m/106y) based on the above data. This is Sea Drilling Project. The oolitic limestone was brought up somewhat less than the figure taken from Sclater et al.'s from 83 and 106 meters subbottom depth in Cores 3 and 4 (1971) general subsidence-rate curve for the north Pacific of Hole 202 on Ita Matai Seamount. Drilling of the (about 40 m/106y for crust as old as early Eocene). seamount was undertaken at the end of Leg 20, when the poor state of repair of the drilling gear prohibited further COLOR, TEXTURE, AND POROSITY drilling in deep water. Water depth at this site is 1515 The oolite is of white yellowish to pale tan color except meters. Thus Cores 3 (45 cm recovery) and 4 (35 cm for the uppermost 10 cm of Core 3, which displays shades recovery) come from a total depth of 1598 and 1621 of gray. meters, respectively. Ita Matai Seamount is located at the Individual ooids displaying a distinct nucleus range in eastern margin of the Caroline Abyssal Plain (Figure 1). The size from 0.12 to 1.45 mm in diameter. Skeletal fragments location of Site 202 is 12°40.90'N, 156°57.15'E. associated with the ooids range up to 3 mm. -

LATEMAR CARBONATE BUILDUP, DOLOMITES, NORTHERN ITALY by S
FORMATION OF REPLACEMENT DOLOMITE BY INFILTRATION OF DIFFUSE EFFLUENT: LATEMAR CARBONATE BUILDUP, DOLOMITES, NORTHERN ITALY by Sarah Katherine Carmichael A dissertation submitted to Johns Hopkins University in conformity with the requirements for the degree of Doctor of Philosophy Baltimore, Maryland July, 2006 © 2006 Sarah Carmichael All rights reserved Abstract Massive dolomite typically forms at depth and elevated temperature through replacement of limestone by its reaction with flowing dolomitizing fluid. Analysis of the spatial distribution of elements, isotopes, and heat with transport theory leads to insights into the flow system that produced dolomite in the Latemar carbonate buildup. Dolomitization was arrested, and both dolomite and unreacted limestone well-exposed in three dimensions. Boundaries between the dolomitized and undolomitized regions were mapped on meter to kilometer-scales. The distribution of dolomite directly images an orthogonal lattice of interconnected vertical tube-like and bedding-parallel sheet-like fluid flow channels. The 87Sr/86Sr of Latemar dolomite and the salinity of fluid inclusions in dolomite, previously measured by others, imply that a seawater-derived fluid was the dolomitizing fluid. Dolomite has δ18O = 21.5-27.4‰ (VSMOW), corresponding to temperatures of 50-90°C (assuming equilibration with fluid of δ18O = 0). Electron microprobe and LA- ICPMS data for the dolomite show enrichment in Fe (1,600-19,000 ppm), Mn (66-430 ppm), and Zn (1.7-16 ppm) relative to unreacted limestone. The concentrations of Fe and Zn in dolomite display a positive linear correlation with that of Mn; concentrations of other transition metals show no correlation with Mn. These data suggest that the dolomitizing fluid is analogous to modern diffuse effluent at mid-ocean ridges, and was a mixture of seawater and hydrothermal fluid produced by reaction between seawater and rocks of the adjacent Predazzo igneous complex that was the driving mechanism for ii dolomitization. -
Mineral Resources of the Illinois Basin in the Context of Basin Evolution
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.
