Title

Mapping landslide-generated pseudotachylyte in Dry Creek Canyon, Utah

Abstract

Although pseudotachylyte is typically associated with localized, high-stress environments such as faults and shear zones, in some cases it is known to have been generated by catastrophic landslide events.  Newly mapped occurrences of pseudotachylyte in Dry Creek Canyon, near Alpine, Utah, may provide additional evidence for the emplacement of the East Traverse Mountains through such an event.  This slide most likely originated ~16 km NE of its current location, generating pseudotachylyte through frictional heating along its base.  The pseudotachylyte found in Dry Creek Canyon is preserved in two highly fractured, cataclasite-rich outcrops of Little Cottonwood Stock (LCS), which are surrounded by undisturbed LCS. These features are independent of both the Wasatch and Fort Canyon Faults.  Further mapping of the extent and character of this highly deformed zone will lead to a better understanding of the event during which it formed.
