This book was released on 2012-12-06 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thougtit that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 31 (thesis year 1986) a total of 11 ,480 theses titles trom 24 Canadian and 182 United States universities. We are sure that this broader base tor these titles reported will greatly enhance the value ot this important annual reterence work. While Volume 31 reports theses submitted in 1986, on occasion, certain univer sities do re port theses submitted in previousyears but not reported at the time.

Available in PDF, EPUB and Kindle. Book excerpt: The Sierra de la Parra area includes about 660 square miles in northeast Chihuahua, Mexico. The area is on the eastern margin of the Chihuahua Trough, a relatively narrow, northwest-southeast trending negative feature flanked by the Aldama and Diablo Platforms. During the Late Jurassic and Cretaceous 12,000 to 21,000 feet of basal evaporites, limestone, marl, shale and sandstone accumulated in the trough. In contrast, on the Diablo Platform, 15 miles to the east, less than 2,800 feet of sediments, devoid of evaporites, were deposited. A zone of recurrent faulting along the western margin of the Diablo Platform marks the eastern limit of the Chihuahua Tectonic Belt. This zone separates the predominantly block faulted platform rocks to the north and east from the intensely and complexly deformed rocks of the flanking basin. Laramide movement along this boundary fault zone tilted the Mesozoic basin rocks eastward producing a décollement on the evaporite section and producing subsequent folding and thrusting immediately east of the evaporite basin. Complex disharmonic folding caused by evaporite, shale, and marl flowage is present in thrust plates at all scales up to fold amplitudes of 10,000 feet. Normal faulting of Cretaceous rocks in the upper plate was caused by evaporite flowage into anticliines from adjacent areas. The La Parra and Cipress faults trend N. 40° W. and are anomalous to Laramide structures in the area. These faults probably lie along older Paleozoic fault trends which were reactivated in the Laramide orogeny and late Tertiary. The Palo Pegado, Cipress, and associated boundary faults of the Presidio graben represent Tertiary reactivation along the platform edge fault zone. Although faulting commenced with the advent of volcanic activity, most displacement on the Tertiary faults took place after most of the volcanic related deposition ceased. Several thousand feet of regional uplift probably took place during this faulting. Although block faulting occurred in the intensely deformed area, it is questionable whether it resulted from basement displacement or further flow of evaporites. Bolson fill was deposited over downfaulted blocks during Late Tertiary and Quaternary. Small Quaternary fault scarps indicate continued tectonic activity.

Available in PDF, EPUB and Kindle. Book excerpt: The geologic map of El Cuervo area shows distribution of stratigraphic units ranging in age from Jurassic (?) to Recent. Outcropping strata are principally Cretaceous in mountainous areas and Cenozoic in bolson areas. From the Late Jurassic Epoch until the Late Cretaceous Epoch the Chihuahua Trough was a negative feature with respect to adjacent platforms and 10,000 to 18,000 feet of Jurassic-Comanchean sedimentary rock, including a thick basal evaporate sequence, accumulated in it; whereas on the adjacent Diablo Platform of Texas about 3,000 feet of sedimentary rock accumulated. The lower part of the Mesozoic sedimentary record shows a gradual transgression, interrupted by numerous minor regressions, from the Chihuahua Trough onto the Diablo Platform. The upper part of the record shows a regression. The eastern edge of a Jurassic (?) evaporite basin is in the eastern part of the area. Neocomian-Aptian formations are dominantly siliciclastic. Middle Albian formations are dominantly siliciclastic in the eastern part of the area, but are predominantly shallow-water carbonate to the west. Late Albian-early Cenomanian formations are limestone with subordinate shale. During the Cenomanian Epoch siliciclastic deposition again became dominant and the medial Cenomanian-Senonian formations record a transition from marine to continental deposition. Mesozoic and Paleozoic "basement" rocks were deformed during the Late Cretaceous-Early Tertiary Laramide orogeny. Jurassic (?) evaporites acted as a décollement zone between Mesozoic and Paleozoic rocks. Major thrust faults, over-thrust toward the east, developed along the eastern edge of the evaporite basin in El Cuervo area. During thrust-faulting, evaporites were diapirically injected into younger rocks along thrust- and tear-fault zones. As evaporites flowed into diapirs and cores of anticlines, blocks settled differentially into space abandoned and chaotic patterns of normal faults resulted. Olivine-diabase sills and dikes and amphibole-rich rocks (where olivine diabase was intruded into and contaminated by evaporites) may have formed during early stages of Laramide deformation. During and after Laramide deformation denudation created a surface of erosion in the area. During Early Tertiary erosion as evaporites were removed, collapse structure developed over diapirs, which had been injected along tear-fault zones. At several places in near- vertical beds on flanks of folds, as erosion removed nonresistant beds, gravity developed flaps and detached flaps in adjacent resistant beds of limestone. During late Eocene-early Oligocene time flow rocks, ignimbrites, and associated sedimentary rocks were deposited in widely scattered, topographically low areas. Volcanic and associated rocks, deposited in collapse features, were deformed as erosion of evaporites continued and they foundered into evaporites. Two porphyritic andesite intrusions are associated with Laramide faults; one is in the core of a large anticline. In the southeastern part of the area several trachyte intrusions along east-trending joints formed dikes. Subsequent to vulcanism, the region was uplifted from elevations near sea level to thousands of feet above sea level and Late Tertiary block-faulting was superimposed on Laramide structure in the eastern part of El Cuervo area. Intrusion of olivine-biotite "peridotite" may have accompanied faulting or immediately followed the main episode of faulting. Thick sections of bolson fill were deposited in the Presidio and Benigno grabens as a consequence of block-faulting. Although some Laramide faults may have been reactivated during Tertiary block-faulting, major Tertiary faulting did not take place west of the eastern front of the easternmost range of the Chihuahua Tectonic Belt.
