Abstract

The east-central part of the left-lateral Garlock Fault, in southeast California, is associated with three broad folds that trend and plunge northeast. The folds, which lie north, south, and astride the fault, postdate deposition of alluvial gravels that at one time formed a continuous northwest-sloping fan. Corrected tilting rates vary from about 2.5?? to 4.7??/m.y.; the total shortening of about 7.5 m developed at a minimum rate of 12.5 m/m.y. The orientations of these folds imply northwest-southeast compression, which is anomalous when viewed in the context of regional tectonics. These anomalous features are interpreted as evidence that episodes of NW-SE compression along the Garlock Fault do occur, and although oriented about 90?? from the average of conventional - and presently observed - compression directions, they have occurred during much (most?) of the Cenozoic Era, including the past 0.6 m.y. -from Author
