Fosdick Lab at Indiana University
Basin Analysis & Helium Thermochronology Laboratory
Our research group studies the long-term evolution of orogenic belts during their growth and denudation as recorded in the sedimentary record. Key research questions and themes include:
(1) How does redistribution of rocks via erosion and sedimentation influence depositional and deformational patterns?
(2) What are the controls and feedbacks among tectonic activity, sediment supply, global sea level, and climate?
(3) What mechanisms drive basin subsidence and large-scale sedimentation patterns?
(4) How can we improve provenance analysis methods to better constrain sediment source areas and regional basin paleogeography?
The BAHTL facility will house a helium gas extraction and measurement system designed for low-temperature (U-Th)/He thermochronology to study thermal and exhumational histories of the Earth's crust and sediments. The laboratory also includes a clean lab for mineral dissolution chemistry, a polarized stereomicrocope for sample preparation, petrographic microscope, and student office space. Lab renovation is complete and the helium system build is underway (Santa Cruz Laser Microfurnace custom design).
