Abstract The Quaternary Big Pine (BP) volcanic field in eastern California is notable for the occurrence of mantle xenoliths in several flows. This points to rapid ascent of basalt through the crust and precludes prolonged storage in a crustal reserv

Origin of low Mg# hawaiites carrying peridotite xenoliths from the Cima volcanic field, California, USA: Evidence of rapid magma mixing during ascent along intersecting fractures

Autor: Sarah K. Brehm, Rebecca A. Lange

Publikováno v: GSA Bulletin. 135:575-594

The Cima volcanic field, in the southern Basin and Range province (California, USA), includes >70 eruptive units over the last 8 m.y. The youngest (≤1 Ma) are low Mg# (≥56) hawaiites derived from an asthenospheric mantle source. The Cima hawaiite
