A JOINT XRF-δ<sup>13</sup>C<sub>carb</sub> CHEMOSTRATIGRAPHIC APPROACH FOR CHARACTERIZING PALEO-ENVIRONMENTAL PROCESSES IN THE MUDSTONE-DOMINATED WOLFCAMP FORMATION OF WEST TEXAS

Tamakloe, Frank 01 January 2019 (has links)
The Late Paleozoic Ice Age represents a dynamic period in Earth system history recording a shift from icehouse to greenhouse conditions. Concomitant with this change was a series high-frequency, high-amplitude sea level fluctuations leading to the deposition of “Kansas type” cyclothems in the Mid-Continent, and a similar rhythmic expression of interbedded shales and carbonates in the Midland Basin. Stable isotope geochemistry is a particularly powerful tool when examining these mud-rich successions because changes in organic matter partitioning may be recorded first in δ13CDIC of sea-water and consequently in δ13Ccarb of marine rocks. The δ13Ccarb record may also illuminate early and late-stage diagenetic processes and associated destruction of organic matter. This study used high-resolution x-ray fluorescence (XRF) and δ13Ccarb measurements to analyze paleo-environmental conditions in two cores within the Midland Basin Wolfcamp Formation. Using this approach, the combination of more positive δ13Ccarb measurements and enrichment of redox-sensitive elements reflect conditions more favorable for organic matter enrichment in the distal core. Additionally, four (< 6 in.) early-diagenetic intervals have been identified representing prolonged periods of reduced or non-deposition based on sharp negative δ13Ccarb excursions. These horizons are proposed as potential chronostratigraphic tie-points between the two core localities.

Tracking Changes in Early Paleoindian Technology and Adaptations on the Southern Plains Periphery

Jennings, Thomas 2012 May 1900 (has links)
This dissertation presents new data on early Paleoindian stone technologies in the Southern Plains periphery. Analyses of lithic artifact assemblages show that significant technological changes occurred between the transitions from pre-Clovis to Clovis and from Clovis to Folsom/Midland. After an initial introduction to the problems in chapter one, a detailed technological description of the pre-Clovis assemblage from the Debra L. Friedkin site, Texas is presented. Site-scale and general technological comparisons to Clovis reveal similarities and differences. I conclude that the pre-Clovis assemblage at Friedkin cannot be considered Clovis, but could represent an ancestral technological assemblage. The third chapter presents the analysis of Clovis bifaces from the Hogeye site, Texas. I identify patterns in the biface reduction process and suggest that these patterns could be use to distinguish between regional Clovis cultural signatures and the idiosyncrasies of individual Clovis flintknappers. The fourth chapter compares Clovis and Folsom/Midland technologies and site-use at a single site, the Debra L. Friedkin site, Texas. I show that while late-stage biface reduction and point production were the focus of both occupations, Folsom/Midland groups also reduced some early- or middle- stage bifacial cores. More broadly, the Friedkin site shows that Clovis and Folsom/Midland settlement along Buttermilk Creek varied. Ultimately, this dissertation provides new evidence of possible Clovis origins, documents Clovis biface reduction signatures, and identifies site-use and technological similarities and differences between Clovis and Folsom/Midland. Defining and comparing early Paleoindian adaptations and technologies is key to understanding how humans dispersed into North America and how they adapted to new and changing environments during the last Ice Age.

Genetic Pore Types and Their Relationship to Reservoir Quality: Canyon Formation (Pennsylvanian), Diamond M Field, Scurry County, Texas

Barry, Travis 2011 December 1900 (has links)
Carbonate reservoirs may have a variety of porosity types created by depositional, diagenetic, and fracture processes. This leads to the formation of complex pore systems, and in turn creates heterogeneities in reservoir performance and quality. In carbonate reservoirs affected by diagenesis and fracturing, porosity and peremeability can be independent of depositional facies or formation boundaries; consequently, conventional reservoir characterization methods are unreliable for predicting reservoir flow characteristics. This thesis provides an integrated petrographic, stratigraphic, and petrophysical study of the 'Canyon Reef' reservoir, a Pennsylvanian phylloid algal mound complex in the Horseshoe atoll. Core descriptions on three full-diameter cores led to the identification of 5 distinct depositional facies based on fundamental rock properties and biota. Fifty-four thin sections taken from the core were described are pores were classified using the Humbolt modification of the Ahr porosity classification. In order to rank reservoir quality, flow units were established on the basis of combined porosity and permeability values from core analysis. A cut off criterion for porosity and permeability was established to separate good and poor flow units. Ultimately cross sections were created to show the spatial distribution of flow units in the field.

Riding Red Ink: Public Ownership of Mass Transit in Indianapolis

Wilhite, Ryan Daniel January 2011 (has links)
**Note** During the research process, IndyGo donated some of the resources cited within this paper to the Indiana Historical Society. That collection has not been archived yet. Further, IndyGo may have placed other documents (created during the time of public ownership) in the Indiana State Archives or the Indiana State Library. / Indiana University-Purdue University Indianapolis (IUPUI) / Today, most urban mass transit providers are publicly owned. Just a few decades ago, and for a majority of the history of mass transit, private owners provided transportation for communities. The decline of private ownership in Indianapolis resulted in transit crisis that pitted private owners against local government, riders and community groups. Advocates lambasted the private owners for their profit-first tactics, pointing to the dividends gained by the private owners. These owners, the Midland Transportation Corporation, also owned the mass transit companies in Milwaukee, Wisconsin and Louisville, Kentucky. Indianapolis politicians, residents and newspapers, all firmly conservative, hoped private owners could continue to operate Indianapolis Transit Systems without public assistance. The imminent failure prompted a discussion of the future of transportation in the city of Indianapolis. Community groups hoped the new public corporation would increase service for Indianapolis and not continue the skeleton system managed by the private owners. A storm of uncontrollable events prevented the robust expansion of the new public corporation and its lack of funding resulted in a continuing decline of service, much akin to the private owners that were abhorred by transit riders. Public ownership in Indianapolis revealed the importance of public ownership in the historiography of mass transportation and urban history. The regional investigation of Midland Transportation confirmed the notion of transit as a unique industry, both in its industrial relations and influence of the locality. The basic rationale for public ownership in Indianapolis would be the most important: the provision of public transportation for those unable to afford private transportation to obtain necessary services.
