Paleomagnetic data, coupled with detailed geological analysis of the southeastern Goldstone Lake region, indicate that lower Miocene volcanic and epiclastic rocks of the Pink Canyon area have been folded, faulted and tectonically rotated similar to 28.4 +/- 9.0 degrees clockwise about a vertical axis; identical rocks lying to the west across the Goldstone Lake Fault (east branch) have been rotated 9.6 +/- 7.4 degrees. The Coyote Canyon Fault is locally folded about a vertical axis similar to 25 degrees in a clockwise sense in the Pink Canyon area. Timing relationships indicate that rotation is post-early Miocene; regional relationships imply that deformation is late Miocene to Holocene in age. These relationships imply that tectonic rotation is local rather than regional in extent as proposed by some tectonic models. The results of this study are generally consistent with the Dokka and Travis [1] model and the subsequently revised Dokka model [2] of strain partitioning in the northeastern Mojave Desert block.
