The Split Cinder Cone in southern Death Valley is a Pleistocene-age volcano that has been split and displaced by movement along the active Southern Death Valley Fault Zone. Located near West Side Road and Highway 178, the western part of the cone has been offset approximately 225 meters north relative to the eastern portion by right-lateral strike-slip faulting, a relationship that can be observed both in the field and on satellite imagery. In addition to the beautiful structural features visible at this site, the cinder cone preserves several notable volcanic features, including volcanic bombs and chilled margins. Another important characteristic of this outcrop is the presence of abundant xenoliths, which were brought to the surface by the lava and are exposed throughout the cinder cone. Some of these xenoliths are felsic in composition, indicating that the magma incorporated shallow granitic country rock during ascent. Five samples were collected from this site, including a volcanic bomb and several xenoliths: BH250-241a, BH250-241b, BH250-241c, and BH250-241e. basaltic volcanism bomb sag Chilled margins cinder cone country rock fragments crustal xenoliths Death Valley Death Valley National Park desert geology displaced volcano fault offset felsic xenoliths geomorphology granitic xenoliths igneous Pyroclastic deposits right-lateral fault scoria Split Cinder Cone strike-slip faulting volcanic bombs Volcanic Breccia volcanic cone Volcanic textures xenolith xenoliths
