However, the definition of fault-plane geometries demands detailed prestack imaging including nonhyperbolic, fault plane reflections. We use minimum preprocessing, a well-constrained, reliable velocity model for shallow depths, and Kirchhoff prestack depth migration. Tectonic setting Death Valley is a region of active extension and recent volcanism. The northeastern boundary of the basin is controlled by the dextral Northern Death Valley-Furnace Creek fault zone and the southwestern boundary is controlled by the dextral southern Death Valley fault zone. The central part of the basin is characterized by normal faulting.
Death Valley is therefore a half-graben basin.
A dipping event that extends from above a midcrustal reflection at about 6 s to near the surface, by an offset cinder cone, was suggested to be a reflection from a magma conduit or feeder dike that has now consolidated. The shading indicates relative elevations. Solid, thin lines indicate faults. NTS is the Nevada Test Site. The original processing and interpretation of Serpa et al.
