CommentThis and the preceding 5 samples nos. 43-48 are part of an extensive field of thin, alkali-olivine basalt flows which cover nearly 300 square miles east and south of Mono Lake in Nevada and California. The basalts, which are intercalated with small volumes of rhyolite, andesite and latite, were erupted from numerous local centers between 2.6 and 4.5 m.y. ago. The aggregate thickness of these flows locally exceeds 600 feet. Their volume is estimated as 65 km^3 Gilbert and others, 1968.
