Research Interest: Fluvial Sedimentology (Petrology, Mineralogy & Geochemistry) & Geomorphology
My research lies with the sediment transportation and natural sorting of placer deposits at the streambed of Snowy Range Mountain. Placer deposits, which are rich concentrations of heavy minerals like gold, play an important economic role, yet the exact physical processes behind their formation are still not fully understood. My research seeks to examine the hypothesis that gold accumulation in the streambed of placer formation is largely driven by hydraulic sorting mechanisms, such as- entrainment, suspension, transport, and shear sorting based on settling velocities of the particle. So, my major goal is to establish a global dataset of placer formation.
Current Research
➡️I am commencing the research under the supervision of Prof. Brandon McElroy (advisor), who has expertise in sediment transportation and geomorphology of alluvial fans and rivers. My research integrates fieldwork and lab analysis (Wilfley Table Test, Dry Sample Analysis, Settling Velocity Test, SEM-EDX, XRD and Petrology). While several empirical models exist to predict settling velocity, the comprehensive approach of Dietrich (1982), which incorporates particle size, shape, and roundness, is considered the most robust for natural sediments. This project will apply this theoretical framework to a real-world system to test its predictive power for placer occurrence, genesis and provenance.
