Geological and Tectonic Mapping of Alaska.

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. 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.
