|Mark A Helper|
Dr. Helper is a field geologist, a generalist whose interests span igneous and metamorphic petrology, structural geology, tectonics, mineralogy and planetary field geology. His current research explores geochemical and isotopic similarities of Proterozoic and Archean crust in East Antarctica and the southwestern U.S., the Precambrian geology of Texas, and the origin of epidote blueschists in the Klamath Mountains of northern California. Recent senior honors theses under his supervision have examined the mineralogy of Texas ...
