"Something Old, Something New: Revisiting Permian to Jurassic tectonics in the Klamath Mountains, Northern California."
Speaker: Kathryn Metcalf, Ph.D., CSU Fullerton
The Klamath Mountains straddle the California-Oregon border and are an amalgamation of
accreted terranes. Despite the Klamath Mountains being the birthplace of the term
"tectonostratigraphic terrane," the ages, correlations, and tectonic settings of many Klamath
terranes are still debated.
One of the most enigmatic terranes is the Rattlesnake Creek terrane (RCT), a mélange of
metamorphosed sedimentary and igneous blocks with a volcanic and sedimentary sequence
deposited on top. Recent work shows that the overlying RCT cover sequence has a North American
provenance but formed after accretion to the continental margin, so it is unclear if the basement
mélange formed proximal or distal to North America. My research group conducted field mapping,
petrography, and zircon geochronology.
Dr. Kathryn Metcalf is an Assistant Professor of Structural Geology at California
State University, Fullerton. She earned a B.S. in geology and geophysics from
the University of North Carolina, Chapel Hill before moving out west to
complete an M.S. and Ph.D. in geosciences from the University of Arizona.
Dr. Metcalf's research focus is on the structural geology, tectonics,
geodynamics, and regional geology of convergent margins. She uses geologic
mapping, geophysics, geochronology, and petrography to understand
continental collisions, subduction complex accretion and erosion processes,
the impacts of subduction dynamics on continents and the role of the mantle
and lithosphere in surface geology. Many of her research students have been
recipients of awards for outstanding research and proposals at poster
sessions judged by members of the South Coast Geological Society over the
last couple of years.
