Six new U-Pb dates on volcanic units and crosscutting intrusions reveal that the upper parts of both the Inyo Mountains and Alabama Hills sections accumulated during Middle and Late Jurassic time. During this same interval, both sections were steeply tilted and locally folded during one or more episodes of contractile deformation occurring in the east Sierran thrust belt. Differences between the largely undated lower parts of the Inyo Mountains and Alabama Hills sections suggest that they were once located farther apart, then later brought into proximity by thrust faulting or strike-slip faulting. The Inyo Mountains and Alabama Hills sections are similar to partly coeval strata in the White Mountains, in that both contain abundant sedimentary strata that were in part deposited in or near terrain of moderate topographic relief. Together, these areas seem to compose a distinctive arc-marginal depositional province different than that represented by partly coeval strata preserved in pendants to the west.
