Reevaluation of the Shepherd Mountain and Pilot Knob deposits in Southeast Missouri and their genetic connection
(University of Missouri--Columbia, 2023)Iron-Oxide-Apatite (IOA) deposits occur worldwide and are important contributors of Fe, V, Co, P, rare earth elements (REEs) and other critical elements. Southeast Missouri contains numerous iron deposits that have ... -
Assessment of the CO2 sequestration potential of the Morrow-B Sandstone in the Farnsworth Unit, Northern Texas through numerical modeling and laboratory batch reaction experiments
(University of Missouri--Columbia, 2023)[EMBARGOED UNTIL 5/1/2024] The objectives of this study were (1) to investigate the injection and storage of CO2 into the Morrow B Sandstone through numerical non-isothermal reactive transport models, (2) to establish a ... -
The crustal structure of Southwestern Turkey using local seismic data
(University of Missouri--Columbia, 2023)The primary objective of this study is to image the crustal seismic structure of southwestern Turkey by employing the double-difference travel time seismic tomography. In addition, this study accurately located seismicity ... -
Inferring the environmental conditions present during early tetrapod terrestrialization from skeletal [delta]18O values
(University of Missouri--Columbia, 2023)To test the extent of marine influence in the Joggins Formation, Nova Scotia, Canada and the possible habitat segregation and the net moisture balance at the Red Hill roadcut exposure of the Duncannon Member of the Catskill ... -
A geochemical, taxonomic, and phylogenetic investigation of paleozoic arthropods : case studies on the cambrian spice event and the silurian waukesha lagerstatte
(University of Missouri--Columbia, 2020)This thesis details two stand-alone projects: Chapters 1 and 2 comprise a quantitative investigation of controls on the [delta]13C record of the Steptoean Positive Carbon Isotope Excursion (SPICE); Chapter 3 describes a ... -
Spatiotemporal patterns of earthquakes and their implications for earthquake hazards
(University of Missouri--Columbia, 2022)[EMBARGOED UNTIL 5/31/2023] This work focuses on characterizing spatiotemporal patterns of earthquakes, their possible causes, and their implications for seismic hazard assessment. I studied both local and global earthquakes ... -
Another one bites the host : driving forces of increased complex life-cycle parasite traces during the Holocene as affected by sea-level rise in Northern Adriatic, Po Plain Basin
(University of Missouri--Columbia, 2022)[EMBARGOED UNTIL 8/1/2023] Holocene deposits of the Adriatic coastal plain are rich with clams parasitized by trematodes (complex life cycle parasites), as indicated by diagnostic pits on the interior of their valves. ... -
Structural style of the San Francisco Mountains, Sevier fold-thrust belt, Utah
(University of Missouri--Columbia, 2022)[EMBARGOED UNTIL 8/1/2023] The Sevier fold-thrust belt contains thrust sheets that are overprinted by extensional faults, distorting correlations of geologic structures in the region. The Frisco thrust is exposed within ... -
Geochronologic and thermochronologic constraints on the Mesozoic to Cenozoic deformation history of southeastern California
(University of Missouri--Columbia, 2022)[EMBARGOED UNTIL 8/1/2023] Southeastern California hosts a complex zone of deformation defined by structures related to the San Andreas fault, such as the sinistral Garlock fault and the largely dextral eastern California ... -
Constraining the slip rate of the Owl Lake Fault by using LiDAR data and fault scarp degradation models
(University of Missouri--Columbia, 2022)[EMBARGOED UNTIL 8/1/2023] The Owl Lake Fault is an active, 19 to 25-km-long, left-lateral strike-slip fault that divaricates NE from the Garlock Fault toward Death Valley in eastern California and transfers regional strain ... -
Vignettes on preservation, preparation, and paleoecology
(University of Missouri--Columbia, 2022)[EMBARGOED UNTIL 8/1/2023] Preservation exercises strong control over what can be observed and interpreted from the fossil record. The research projects presented here seek to examine the ways in which certain preservational ... -
