Vignettes on preservation, preparation, and paleoecology
(University of Missouri--Columbia, 2022)
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 types clarify some aspects ...
Biotic interactions in the fossil record: an investigation on the patterns of predation and parasitism of Plio-Pleistocene bivalves from the Nashua Formation of Florida
(University of Missouri--Columbia, 2022)
[EMBARGOED UNTIL 8/1/2024] The present study investigated for patterns of predation and parasitism among a collection of Plio-Pleistocene bivalves from the Nashua Formation of Florida. The processed sample yielded 2010 ...
Spatiotemporal patterns of earthquakes and their implications for earthquake hazards
(University of Missouri--Columbia, 2022)
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 in the view of complex ...
Geochronologic and thermochronologic constraints on the Mesozoic to Cenozoic deformation history of southeastern California
(University of Missouri--Columbia, 2022)
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 shear zone, as well as ...
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)
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. Surges in parasite prevalence ...
Structural style of the San Francisco Mountains, Sevier fold-thrust belt, Utah
(University of Missouri--Columbia, 2022)
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 the San Francisco Mountains ...
Constraining the slip rate of the Owl Lake Fault by using LiDAR data and fault scarp degradation models
(University of Missouri--Columbia, 2022)
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 to the fault systems in ...
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 ...
A shellabration of early life : exploring the taphonomy, diversity, and distribution of small shelly fossils surrounding archaeocyathid reef systems in the Harkless System, Death Valley, NV
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 8/1/2024] Cambrian archaeocyathid reef systems represent the earliest metazoan-dominated topographically complex bioconstructions in the rock record and provide valuable insights into community composition ...
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 ...
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 ...
Determining the relationship between the Garlock fault and the Eastern California shear zone through detailed digital mapping and age characterization of faulted landforms, Southeastern California
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 8/1/2024] Southeastern California is known for complex fault networks that accommodate strain from Pacific-North American plate convergence. The 250-km-long, left-lateral Garlock fault is integral to this ...
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 ...
