WebThe 0.76 Ma Bishop Tuff, from Long Valley caldera in eastern California, consists of a widespread fall deposit and voluminous partly welded ignimbrite. The fall deposit (F), exposed over an easterly sector below and adjacent to the ignimbrite, is divided into nine units (F1‐F9), with no significant time breaks, except possibly between F8 and F9. WebThe Bishop Tuff is the >600 km3 (magma volume) product of the 0.765 Ma caldera-forming eruption at Long Valley in eastern California. It is an archetypal example of a compositionally zoned high-silica rhyolitic eruption deposit and one of the most thoroughly studied rhyolitic systems in the world (Hildreth 2004; Hildreth and Wilson 2007).
