Pg. M10. Danger Point tuff. Essentially glassy volcanic debris of andesitic to rhyolitic composition. Glass is largely altered to montmorillonite clay. Total thickness probably not more than 400 feet, of which less than half is exposed in scattered sections representing different parts. Underlies Jarbidge rhyolite. Rests unconformably on Paleozoic(?) metamorphic rocks, Dead Horse tuff, and Meadow Fork formation (new). Age is late(?) Miocene; lithologic resemblance and stratigraphic relationship with Jarbidge suggests units are approximately same age. Report includes geologic map. Adopted by the USGS.
Type locality: Danger Point, a prominent ridge on east side of Coon Creek valley, in southwest part of Jarbidge quadrangle, Elko Co., northeastern NV. Named from Danger Point. Also exposed on eastern side of Copper Basin.
