Linkage and Reactivation Along the Northern Hurricane and Sevier Faults, Southwestern Utah
Abstract This roadlog covers two days of field trips in the Colorado Plateau – Basin and Range Transition Zone and the High Plateaus of southwestern Utah. The focus of the trip is the structural development of and deformation along two long, geometrically segmented, young faults: the Hurricane fault (Day 1) and the Sevier fault (Day 2). The development of these faults encompasses interaction with structures of the mainly Mesozoic Sevier orogenic belt and linkage of individual relatively short normal faults to form long faults. Understanding the amounts and recency of slip along these faults requires an understanding of the Upper Paleozoic, Mesozoic and Cenozoic stratigraphy. Many of these stratigraphic units will be seen during the course of the trip. In addition, past landslides and potential earthquake in the region will be observed and considered.
