| Comment | This and the preceding 4 samples are from a sequence of widespread welded latite ignimbrites which crop out in a broad belt crossing Mono Basin in a northwesterly direction. They fall into two age groups, an older one from 11.1 to 11.9 m.y., and a younger one from 9.0 to 9.8 m.y. The older of the two groups crops out in the southeastern part of the area, and the younger to the NW. The Anchorite Hills is the dividing line. The two age groups are probably from different eruptive centers Gilbert and others, 1968. The thickest exposures, 700', occur in Huntoon Valley locations 50, 51, 52, but generally the ignimbrites are relatively thin and extensive. |
