Edward Hildreth, Judith Fierstein, Fred M. Phillips, Andrew T. Calvert
2022, GSA Bulletin (134) 1143-1159
Tectonic interpretation of the central Sierra Nevada—whether the crest of the Sierra Nevada (California, USA) was uplifted in the late Cenozoic or whether the range has undergone continuous down-wearing since the Late Cretaceous—is controversial, since there is no obvious tectonic explanation for renewed uplift. The strongest direct evidence for late...
