1. Lyon, Trey Saxon. Determining the Depositional Environment of the Lower Eagle Ford Group in Lozier Canyon, Antonio Creek, and Osman Canyon: An Out Crop Study of Bedding Features a Study of Bedding Features at Outcrop Scale or in the Outcrop.

Degree: MS, Geology, 2015, Texas A&M University

The Eagle Ford Formation is currently the most economically significant unconventional resource play in the state of Texas. There has been much debate as to the environment of deposition for the lowermost Facies A of the Eagle Ford in outcrop exposures in Lozier Canyon, Texas. Two conflicting hypotheses were proposed: 1) Sedimentary structures in Facies A are hummocky cross-stratification (HCS) and swaley cross-stratification (SCS), which indicates a shelfal depositional environment above the storm wave base (SWB). 2) Sedimentary structures in Facies A are a mixture of diagenetically separated contourites, turbidites, and pinch-and-swell beds, which indicate a distal-slope depositional environment below SWB. This research used field work, three-dimensional analysis of sedimentary structures, measurements of ripple height, and laboratory analysis to interpret the environment of deposition. The results of these observations and data suggest that the sedimentary structures in Facies A record a depositional environment above SWB. Observation of cross-bedded structures in three-dimensions reveals (i) isotropic truncation of laminae; (ii) symmetric rounded ripples; (iii) large variations in laminae geometry, truncation, and dip inclination, attributed to fluctuations in storm intensity, frequency, and duration; and (iv) and bidirectional downlap and reactivation surfaces associated with oscillatory flow above the SWB. This study interprets cross-bedded sedimentary structures in Facies A as swaley cross-stratification (SCS) and hummocky cross-stratification (HCS) associated with storm events, and thus places Facies A in a depositional environment above storm wave-base (SWB). Advisors/Committee Members: Giardino, John R (advisor), Laya, Juan Carlos (committee member), Pope, Mike (committee member), Houser, Christopher (committee member).

3. Webb, Grant D. THE DIJET CROSS SECTION MEASUREMENT IN PROTON-PROTON COLLISIONS AT A CENTER OF MASS ENERGY OF 500 GEV AT STAR.

Degree: 2014, University of Kentucky

Polarized deep inelastic scattering experiments play a vital role in the exploration of the spin structure of the proton. The polarized proton-proton collider at RHIC provides direct access to the gluon spin distribution through longitudinal double spin asymmetry measurements of inclusive jets, pions, and dijets. This thesis presents the measurement of the dijet double differential cross-section in proton-proton collisions at center of mass energies of √s = 500 GeV. The data represent an integrated luminosity of 8.7 pb-1 recorded by the STAR detector during the 2009 RHIC run. A comprehensive jet analysis was performed to determine the ideal jet algorithm and jet parameters used in √s = 500 GeV collisions at the STAR detector. The cross-section is measured as a function of the dijet invariant mass (30 ≤ Mij ≤ 152 GeV) in the mid rapidity region with a maximum rapidity range of |ymax| ≤ 0.8. This result shows agreement with theoretical next-to-leading order pQCD calculations, motivating the use of dijet asymmetries at STAR to further constrain the shape of Δg(x).
