Petrogenesis of compositionally distinct silicic volcanoes in the Three Sisters region of the Oregon Cascade Range : the effects of crustal extension on the development of continental arc silicic magmatism

Creator:

Hill, Brittain Eames

Abstract:

The Three Sisters region of the Oregon High Cascades has developed three compositionally and petrogenetically distinct silicic (i.e., SiO₂ ≥ 58%) magma systems within the last 600 k.y. These silicic systems evolved from the same High Cascade mafic magma system and developed in the same 20x30 km area of the...

Lower and Middle Devonian carbonate-platform and outer-shelf-basin deposits flanking Railroad Valley, Nevada

Creator:

Nelson, Storr L.

Abstract:

Lower and Middle Devonian strata crop out on the former stable carbonate platform that existed in the Quinn Canyon Range, through the carbonate shelf edge in the Pancake Range, to the carbonate slope and outer-shelf basin in the Reveille Range. The strata of the Reveille Range record a transition from...
