Mid-Tertiary magmatism of the Toquima caldera complex and vicinity, Nevada. development of explosive high-K, calc-alkaline magmas in the central Great Basin, USA

Three calderas in Nevada's Toquima caldera complex (TCC) formed due to eruption of the tuffs at Moores Creek, Mt Jefferson and Trail Canyon. Data suggest that magma erupted from the TCC was oxidized, thermally zoned and water-rich.
