Controlling factors on Mesozoic and Cenozoic metamorphism and deformation in the Maria Fold and Thrust Belt and Colorado River Extensional Corridor, Southeastern California and Western Arizona
The Maria Fold and Thrust Belt (MFTB) and Colorado River Extensional Corridor (CREC) were the sites of atypically extreme compression in Mesozoic time and extension in Cenozoic time, respectively. The orientations of these deformational structures are at odds with the Sevier and Laramide thrust …

Experimental investigations of isotopologue fractionation during microbial methanogenesis
… concentration and redox potential are important controlling factors of carbon (¹³C/¹²C) and hydrogen (D/H) isotope ratios as well as the abundance of methane clumped isotopologues ([delta]¹³CH₃D) during microbial methanogenesis. Chapter 2 uses batch and fed-batch culturing systems to investigate …
