Cynthia Dusel-Bacon

Cynthia Dusel-Bacon is a Scientist Emerita in the Geology, Minerals, Energy, and Geophysics Science Center in Menlo Park, California. Since 1975 she has worked to decipher the geology, geologic setting of syngenetic and epigenetic mineral deposits, and tectonic history of east-central Alaska.

Biography

Cynthia Dusel-Bacon joined the USGS Branch of Alaskan Geology, headquartered in Menlo Park, California, in 1975. In 1977, during her third field season of geologic mapping in east-central Alaska, she was mauled by a black bear and lost both arms as a result of her injuries. Her disability has not kept her from enjoying a long and productive career that includes fieldwork in Alaska, petrologic studies, and publication of results.

Research Focus

Dusel-Bacon’s studies have involved deciphering the geologic and tectonic history of east-central Alaska utilizing geologic mapping, metamorphic petrology, whole-rock geochemistry, trace-element tectonic fingerprinting of (meta)igneous rocks, and geochronology (U-Pb zircon,40Ar-39Ar, and apatite fission track data) generated by collaborating scientists. Her studies also have included correlation of regional events in east-central Alaska with those in the western Canadian Cordillera; the age, character, and tectonic setting of submarine, syngenetic, hydrothermal mineral deposits (both volcanic- and sedimentary-hosted); and compilation of a Metamorphic Facies Map of Alaska.
