Lithogenesis Of The Pennsylvanian Madera Formation Of Palomas Peak, Sandia Mountains, New Mexico., Ronald D. Perkins

Earth and Planetary Sciences ETDs

The Pennsylvanian Madera formation of Palomas Peak in the Sandia Mountains of central New Mexico is a sequence of marine limestone and minor sandstone that ranges in age from Desmoinesian to Virgilian. The limestone is predominantly clastic or bioclastic and the sandstone is arkosic. Lithologic and paleontologic evidence suggests an epineritic to infraneritic environment on a gently subsiding shelf during deposition of the Madera Sediments.

Rhythmic deposition at Palomas Peak is evidenced by alternating clastic and bioclastic limestones which may have resulted from: (1) eustatic changes in sea level, (2) tectonic fluctuations in the downwarping of the shelf, or (3) …

Geology Of The Upper Middle Creek Area Huerfano County, Colorado, J. H. Copeland

Open Access Master's Theses (through 2010)

The Sangre de Cristo Mountains of Colorado and New Mexico are, geologically speaking, relatively unknown. The equivocal nature of our knowledge of the range was a primary reason for studying a portion of it in some detail. Most of the previous studies have been concerned with the northern part of the range in Colorado, in the general area between Salida and La Veta Pass. This work has indicated that the complicated structure which characterizes the northern part of the range becomes simpler to the south. Therefore, a second objective of the current study has been to test this hypothesis. Thirdly, …

Geologic And Ground-Water Reconnaissance Of The Loup River Drainage Basin Nebraska, R. T. Sniegocki, R. H. Langford

United States Geological Survey: Publications

The Loup River and its tributaries drain an area of about 15,230 square miles in central Nebraska. The upper three-fifths of the drainage basin is in the Sand Hills region of Nebraska, and the lower two-fifths is in the loess plains and hills region. An eastward-thinning wedge of semiconsolidated and unconsolidated deposits of Tertiary and Quaternary age underlies the surficial dune sand and loess. These deposits, which are recharged by infiltrating precipitation, contain a tremendous volume of water at least 400 million acre-feet and annually discharge about 1.7 million acre-feet into streams. Although wells supply nearly all the water used …

An Iron Fulgurite From Nebraska, C. M. Riley

Bulletin of the University of Nebraska State Museum

From the time of the ancients man has been impressed with the force of lightning and its effect on the rocks at the surface of the earth. It was Saussure in 1786 who first wrote a scientific account of a true fulgurite, and a wealth of literature has been written about the subject since this time. Many unusual fulgurites have been described, some of which may not truly be the result of lightning. The iron fulgurite is a strange conical object about 3 inches high composed mainly of tiny spheres and filaments of metallic iron intermixed with a small amount …

Geology Of The Northeast Portion Of Des Arc Quadrangle, Iron And Madison Counties, Missouri, Wesley Dean Weixelman

Masters Theses

"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. …

A Review Of Fossilization Processes In Different Sedimentary Environments (With Special Reference To The Time Factor Of Deposition Of Ore Minerals Associated With Fossil Material, In Particular The Coprolitic Phosphate Deposits), Giovanna Reggiori Ligasacchi

Masters Theses

"This thesis offers a cross/section through some principal fossilization processes involving organic matter (animals and plants) during and after sedimentation. The influence of different environments during fossilization is considered. The chemical composition of some classes of living invertebrates and plants is compared with the chemical composition of same organisms as found in consolidated sediments as fossils.

Some literature on carbonates, oxides, silicates, phosphates, and sulphides in fossils is reviewed with particular attention to those instances where the fossils are associated with ore minerals. Special consideration is given to the occurrence and composition of fecal matter in recent and consolidated sediments. …

Geology Of The Copper Deposits In The Eminence Region, Shannon County, Missouri, Lanny Lee Evans

Masters Theses

"Copper has been known to occur in Shannon County, Missouri since the early 1830's. A number of small deposits in an area around Eminence has been worked intermittently up to the present day. Little detailed geologic information is available on these deposits. The geology of the Eminence region consists of Precambrian rhyolite porphyry knobs projecting through dolomites and sandstones of Upper Cambrian and Ordovician age. A conglomerate of limited horizontal extent overlying the Precambrian is found at certain localities within the region. The only structures noted are the structural highs formed where the Paleozoic sediments lap upon the knobs. The …
