Petrology, Geochronology and Structure

Petrology, geochronology and tectonics research at UCSB employs an array of field and lab-based techniques to elucidate the timing and duration of tectonic, geochemical and geodynamic processes operating at scales ranging from the single crystal to the orogen scale. We are particularly interested in understanding the origin of mantle heterogeneities, the timescales and geochemical signature of crustal growth and recycling, and the structural evolution of orogenic systems.
