Conceptual models that describe the essential characteristics of groups of similar deposits
have a long and useful role in geology. The first models were undoubtedly empirical …

Compositional data for> 400 pumice clasts, organized according to eruptive sequence,
crystal content, and texture, provide new perspectives on eruption and pre-eruptive …

The Basin and Range province is a composite Cenozoic taphrogen with a present
configuration and internal geometry derived from superimposed multiple phases of …

Numerous important Miocene and early Pliocene epithermal Au-Ag deposits are present in
the northern Great Basin. Most deposits are spatially and temporally related to two magmatic …

Abstract In the western Great Basin of North America, a system of dextral faults
accommodates 15%–25% of the Pacific–North American plate motion. The northern Walker …

La Pacana is one of the largest known calderas on Earth, and is the source of at least two
major ignimbrite eruptions with a combined volume of some 2700 km 3. These ignimbrites …

The relative timing and magnitude of middle Tertiary extension and volcanism in the Great
Basin (northern Basin and Range province) of the western United States remain …

Structural and stratigraphic relations in the Great Basin indicate widespread pre-middle
Miocene crustal extension that appears to define two north-trending belts. Most extension in …

Unaltered silicic ash fall tuffs are abundant in Neogene sedimentary basins of the western
US and constitute an important record of explosive silicic volcanism in this region. In …

Northeastern Nevada is generally interpreted as an area of large-magnitude Eocene
extension possibly due to gravitational collapse of crust thickened during the Sevier …
