Abstract

The uplifted and westward tilted granitic batholith of the Sierra Nevada, comprises hundreds of Cretaceous intrusions, where sheeted bornhardts stand juxtaposed, and have been exposed to compressional stress during several time periods. Field mapping north of Yosemite Valley identified 79 A-tents with a preferred orientation ENE-WSW suggesting the application of directionally applied stress. The AA. suggest that the A-tents in this part of the Sierra Nevada are related to intrinsic compressional stress imposed on the bedrock during emplacement but before mid-Cretaceous transgression
