Cynthia Dusel-Bacon

Biography

Cynthia is a geologist with the USGS in Menlo Park from 1975 to 2014; continuing with geologic studies as Geologist Emerita.  Her research has focused on the regional geology and tectonics of east-central Alaska and the northern Cordillera; trace-element tectonic fingerprinting of (meta)igneous rocks; syngenetic hydrothermal mineralization (VMS and Sedex deposits); geologic setting of mineral prospects in east-central Alaska; and distribution and petrology of metamorphic rocks in Alaska.  In 1977, during her third field season of mapping in the Big Delta quadrangle of east-central Alaska, she was mauled by a black bear and lost both arms as a result of her injuries.  Fortunately, her disability has not kept her from continuing with fieldwork in Alaska and publishing the results.

 

Research focus

Geologic and tectonic history of east-central Alaska utilizing geologic mapping, metamorphic petrology, whole-rock geochemistry and trace-element tectonic fingerprinting of (meta)igneous rocks, and U-Pb zircon, 40Ar-39Ar, and apatite fission track data generated by collaborating scientists.  Correlation of regional events in east-central Alaska with those in the northern Canadian Cordillera.  General interest in submarine, syngenetic hydrothermal mineral deposits hosted in volcanic and sedimentary rocks (VMS and Sedex deposits) and specific interest in the Bonnifield and Delta VMS deposits of the Alaska Range.  Petrography of igneous and metamorphic rocks.
