Description :
Paleomagnetic records are used to correlate sedimentary sequences from pluvial Lakes Chewaucan and Russell in the western Great Basin. This correlation is the basis forage control in the relatively poorly dated sequence from Lake Chewaucan. The paleomagnetic correlation allow the AA. to assign ages to the pluvial episodes and to draw conclusions regarding their temporal relationship to regional climatic events. The ages of six tephras layers contained in the poorly dated sequence are also constrained as a result of this study.
