A 110-km regional seismic profile in east-central Nevada crosses Neogene east-tilted half-grabens in (from west to east) Railroad Valley (RRV), White River Valley, Cave Valley (CV), Muleshoe Valley and Lake Valley. Variations in the internal architecture of these basins may be related to two factors: (1) differences in structural evolution and (2) position of cross section (i.e., the seismic profile) with respect to major depocenters, accommodation zones, and other along-strike transitions in basin geometry. A detailed grid of seismic data in Railroad Valley and proprietary data from other basins show that without adequate three-dimensional seismic control, one should carefully consider factor (2) before generalizing about factor (1). As illustrations, the authors compare cross section derived from the seismic data across RRV (latitude of Grant Canyon) and CV (latitude of Sidehill Pass). In summary, data from RRV and CV illustrate the complexity of broad basin-bounding extensional fault zones and suggest that listric faulting and stratal rotation are characteristic of basin depocenters, whereas translation above planar bounding faults is characteristic of parts of extensional basins that are removed from the depocenter.
