Mariah is a first year PhD student. She is interested in evaluating and comparing the early sedimentary record of ancient and modern forearc basins from various orogenic regions on multiple continents. Her current research focuses on the initiation and development of the Mesozoic San Joaquin sedimentary basin in central California. To better understand the onset of deposition and provenance of the basal stratigraphy of the San Joaquin basin, she is using a combination of sedimentary basin analysis, detrital zircon U-Pb geochronology, apatite fission track (AFT) and apatite/zircon (U-Th)/He thermochronology, geochemistry, and traditional field work.
