Study Of The Ste. Genevieve Formation At Selected Localities In Southern Illinois And Western Kentucky, Mahlon Jack Apgar Reinhard
Study Of The Ste. Genevieve Formation At Selected Localities In Southern Illinois And Western Kentucky, Mahlon Jack Apgar Reinhard
Masters Theses
"The carbonate rocks of the Mississippian Ste. Genevieve Formation were studied megascopically in four quarries--Cave in Rock, Franklin, Three Rivers, and Fredonia Valley--within a small area of the Illinois-Kentucky fluorspar district and in a drill-core from the Cave in Rock Quarry. The rocks were studied microscopically in seventy-four thin sections prepared from samples from the quarries and the drill-core. The Ste. Genevieve Formation is typically an extremely oolitic, fragmentally fossiliferous limestone which is very light gray to white. The megascopic descriptions of the quarry exposures are presented as measured sections and columnar sections. A detailed log of the drill-core is …

Origin Of Some Recent Tractional Sedimentary Structures In The Rio Puerco Near Bernardo, Socorro County, New Mexico, Lawrence H. Wagner
Earth and Planetary Sciences ETDs
The Rio Puerco, in the area of study, occupies a valley eroded in the Santa Fe formation. The silty alluvium is incised by the present channel of the Rio Puerco to a depth of 10 to 25 feet. The depth of the alluvial fill in the area is not known. The channel is 50 to 300 feet wide with braod meanders interspersed with straight reaches. The Rio Puerco is ephemeral in the lower reaches with flow produced by local rains on the watershed.
Petrography Of The Olalla Stock, Okanagan Mountains, British Columbia, James Anton Sturdevant
Petrography Of The Olalla Stock, Okanagan Mountains, British Columbia, James Anton Sturdevant
Earth and Planetary Sciences ETDs
The Olalla stock is located in the Okanagan Mountains of south-central British Columbia, about 20 miles north of the international boundary. It occupies approximately 6 square miles and consists of late Mesozoic mafic and ultramafic rocks and subordinate alkalic rocks, which have intruded previously folded and metamorphosed sediments of the Triassic (?) Shoemaker Foundation.
The rocks of the stock may be broadly grouped into two major categories: (1) those formed from the differentiation of a crystallizing magma that probably entered during the Nevadan orogeny, and (2) those formed by metasomatic replacement of pyroxenite. The rocks of the first category are, …
The Geology Of The South Mountain Area, Bernalillo, Sandoval, And Santa Fe Counties, New Mexico, Tommy B. Thompson
The Geology Of The South Mountain Area, Bernalillo, Sandoval, And Santa Fe Counties, New Mexico, Tommy B. Thompson
Earth and Planetary Sciences ETDs
South Mountain is approximately 30 miles northeast of Albuquerque in the southern end of the San Pedro-Ortiz porphyry belt. It is a Tertiary monzonite laccolith that intrudes the Permian Abo and Yeso Formations and, in places, the Permian Glori eta Sandstone. The base of the laceolith lies on the Abo except in the southeastern part where it overlies the Mes eta Blanca Member of the Yeso. The incompetence of the Yeso appears to nave allowed the monzonitic magma to spread laterally throughout the stratigraphic interval up to the Glorieta Sandstone which was more resistant and broken only locally by the …

The Lower Devonian Water Canyon Formation Of Northeastern Utah, Michael E. Taylor
The Lower Devonian Water Canyon Formation Of Northeastern Utah, Michael E. Taylor
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
In 1948 Williams subdivided the Jefferson Formation of northeastern Utah into two formations. The upper formation was referred to as the Late Devonian Jefferson Formation and the lower formation the Early Devonian Water Canyon Formation (Williams, 1948, p. 1138). Since that time detailed study of the Water Canyon Formation has not been made. It is the purpose of this investigation to describe in detail the lithology and paleontology of the formation and their implication as to the environment of deposition of Early Devonian time in northeastern Utah.

Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson
Lithostratigraphy And Correlation Of The Mississippian System In Nebraska, Marvin P. Carlson
Conservation and Survey Division
The purpose of this study is to describe and correlate rocks of Mississippian age within the state of Nebraska. Shales, generally classified as "Chattanooga" and commonly referred to as Devonian or Mississippian in the northern Mid-Continent, have been included in this study, although these shales are more generally believed to be Devonian and not Mississippian by most stratigraphers and paleontologists at the present time. Since rocks of Mississippian age are present only in the subsurface of Nebraska, the basic information for this report is derived from the microscopic study of cuttings and cores from test wells drilled within the state.

The Diagenetic Origin Of The Dolomites, Chert, And Pyrite In The Jefferson City Formation., Erik Hans Schot
The Diagenetic Origin Of The Dolomites, Chert, And Pyrite In The Jefferson City Formation., Erik Hans Schot
Masters Theses
"Diagenesis designates all modifications which a sediment undergoes during and following deposition and prior to complete lithification, metamorphism, deep burial, and orogenesis.
Probably the dolomites of the Jefferson City Formation resulted from alteration at, or below the sea floor or the depositional interface and during diagenesis. Diagenetic dolomitization or penecontemporaneous alteration presumably involves a reaction between the calcium carbonate sediments at/or below the sea floor or the depositional interface and magnesium salts in solution or suspension in the basal layer of contacting sea water, or in the initial pr connate water trapped in the sediment.
The cherts of the Jefferson …

Geology Of The Unconsolidated Deposits Of Lake County, Indiana, Reuben J. Vig
Geology Of The Unconsolidated Deposits Of Lake County, Indiana, Reuben J. Vig
Theses and Dissertations
Lake County is in the extreme northwestern corner of Indiana. The county is divided into three physiographic units: (1) Calumet lake plain, (2) Valparaiso moraine, (3) Kankakee glacioflucial plain.
The Calumet lake plain was covered by glacial Lake Chicago. Beach lines show the areal extent of the various phase of the lake’s history. The Valparaiso moraine, a broad upland, trends east-west across the county. An end moraine on the north side of this upland is correlated with the Tinley moraine in Illinois. The Kankakee glaciofluvial plain, formerly marshland, slopes gently from the Valparaiso moraine to the Kankakee River.
The bedrock …
