The authors attempt to integrate new and old observations on the Funeral Mountains, in Death Valley, California, into an integrated model of the evolution of the lower plate in this region. This area consists of a detachment fault. Much effort has been directed toward explaining the development of detachment faults. Extensive petrologic, geochronologic and mapping evidence had been developed. The authors combine thermobarometric data on unsheared metamorphic rock in this region, kinematic analysis of folding in the area, and new geochronologic data from fission track measurements, K-Ar and [sup 40]Ar/[sup 39]Ar dating measurements. Their conclusion is that the data supports the feature of models for detachment faulting which claim that a fault surface dips and undergoes a rotation to a horizontal orientation, accompanied by a comparable tilt of the lower plate. 64 refs., 19 figs., 4 tabs.
