Geology of the Mojave Desert Province

Geologic Framework of the Yucca Valley Region

Sellected findings from USGS-supported research:
  • Detailed mapping of Quaternary surficial materials led to the recognition of an extensional dip-slip fault complex previously unrecognized in the Yucca Valley region. These faults probably are part of the Pinto Mountain fault zone, an east-trending left-lateral strike-slip fault that extends from the Morongo Valley region to beyond Twentynine Palms. The dip-slip faults may reflect a left step in the Pinto Mountain left-lateral zone, thus leading to extension in the Yucca Valley region. Some of these faults ruptured in the 1992 Landers M=7.5 earthquake. The extensional faults have partitioned the Yucca Valley region into structural packages that coincide with known ground-water basins, and thus provide a hydrogeologic framework for siting future recharge fields.
  • Old, tilted sedimentary sequences north and south of Yucca Valley have been interpreted as Quaternary in age by previous workers. By contrast, we interpret these deposits as late Miocene in age. These sedimentary materials contain basement clasts, paleocurrent indicators, and catastrophic debris sheets that may provide insight into the long-term late Cenozoic history of the left-lateral Pinto Mountain fault.
