Book Synopsis Geology of the Northeast Portion of Des Arc Quadrangle, Iron and Madison Counties, Missouri by : Wesley Dean Weixelman
Download or read book Geology of the Northeast Portion of Des Arc Quadrangle, Iron and Madison Counties, Missouri written by Wesley Dean Weixelman and published by . This book was released on 1959 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A geological investigation of the northeast portion of Des Arc Quadrangle in southeast Missouri was completed during the summer of 1958. Exposed Precambrian rocks include, from oldest to youngest, undifferentiated purple rhyolites with an interlayered tile-red rhyolite, andesine basalts with interlayered tuff, and an andesite. A diabase dike intrudes the lower purple rhyolites. The purple rhyolites account for about ninety-seven percent of the Precambrian exposures. Exposed Paleozoic rocks belong to the Bonneterre formation and include three members: (1) Lower Brown dolomite; (2) Light Gray dolomite with Tom Sauk limestone and arkosic sandstone and conglomerate facies; and (3) Upper Brown dolomite. These members correlate with zones 2, 3, and 4, respectively, of McQueen and Stewart for the Bonneterre formation of the Fredericktown area. Residuum derived from the Davis, Derby-Doerun, Potosi, Eminence, Gasconade, and Roubidoux formations covers much of the area. The Precambrian rocks show gentle dips, possibly of primary origin. Locally the tile-red rhyolite is inclined forty degrees. Primary structures include flow layering and poorly developed bedding in the rhyolites, plus contraction joints in all the Precambrian rock units. At least one fault occurs in the purple rhyolites. Initial dips off Precambrian knobs are the main structures in the Paleozoic rocks. Joints related to differential compaction occur around these knobs. Aeromagnetic data appear to correlate well with the calculated susceptibilities for the various exposed igneous rock types of the area, using Slichter's method of calculation. Possible economic use might be made of the Tom Sauk limestone exposed in Marble Creek valley for agricultural lime, in manufacture of portland cement, or for terrazzo. Small quartz veins in the Precambrian rhyolites show no apparent metallic values. Aeromagnetic positive anomalies in the area are not considered indicative of buried iron-ore bodies. A tuff exposed near the Blue School, however, shows a relatively high hematite content and might constitute low-grade iron ore of not more than 5,000,000 tons reserves. Lead ores in the Bonneterre formation are unlikely in the area since the favorable stratigraphic horizon of the nearby Fredericktown area (zone 1 of McQueen and Stewart) is missing"--Abstract, leaves v-vi.
Book Synopsis Rapakivi Granites and Related Rocks by : Ilmari J Haapala
Download or read book Rapakivi Granites and Related Rocks written by Ilmari J Haapala and published by Elsevier. This book was released on 2023-08-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapakivi Granites and Related Rocks tells the story of Rapakivi granites, which are a group of granitic rocks characterized by specific texture (presence of plagioclase-mantled ovoidal to subhedral alkali feldspar megacrysts, two generations of quartz and feldspars) and A-type geochemical composition. Well-known representatives are the Proterozoic rapakivi granites that are found as anorogenic or post-orogenic batholith- to stock-sized intrusive complexes in the Precambrian cratons of Ukraine, Fennoscandia, South Greenland, Canada, United States, Brazil, Venezuela, and Siberia. The current knowledge of the rapakivi granites is largely based on the achievements of three International Geological Correlation Programme projects: IGCP-315 (Rapakivi Granites and Related Rocks) in in 1991-1996, IGCP-426 (Granite Systems and Proterozoic Lithospheric Processes) in 1998-2002, and IGCP-510 (A-type Granites and Related Rocks Through Time) in 2005-2009. After these projects, the research has continued actively utilizing enhanced geochemical methods, in situ geochemistry in particular. Rapakivi Granites and Related Rocks includes this research as well as abundant new geochemical and isotopic data combined with deeper understanding of geotectonic processes now allow more detailed tectonic and petrological modelling of the rapakivi granite magmatism and associated ore mineralization.

Book Synopsis Stratigraphy and Correlation of Precambrian Volcanic Rocks, Eminence, Missouri by : Henry Hugh Fisher
Download or read book Stratigraphy and Correlation of Precambrian Volcanic Rocks, Eminence, Missouri written by Henry Hugh Fisher and published by . This book was released on 1969 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: "A portion of the Precambrian rocks located in the vicinity of Eminence, Missouri are studied and describes. These rocks are exposed as rhyolitic knobs protruding through hills of Ordovician sediments. The Precambrian rocks under study consist principally of rhyolite, with smaller amounts of tuff and creccis. The rhyolite is a potash rhyolite porphyry, both flow banded and unbanded, with phenocrysts of kaolinized orthoclase in a matrix of quartz and orthoclase. The tuffs contain devitrified glass shards and occasional ash balls such as those exhibited at Cott Mountain. A stratigraphic sequence was determined with the oldest rocks to the south at Stiegel Mountain and the younger rocks at Coot Mountain to the north. The tuffs occur between rhyolite flows. The entire sequence has a general dip to the north; but local variations in dip and strike occur. Basal conglomerate formed from rhyolite boulders occurs with the Ordovician sediments, particularly at the Little Rocky Creek Ford knob. The possibility that the Eminence rhyolites are ignimbrites was studied and rejected"--Abstract, leaf ii.
