▪ Abstract Cenozoic extension in the western United States presents a complex interrelation
of extension, volcanism, and plate boundary tectonics that defeats simple notions of “active” …

All normal-fault systems must terminate both along and orthogonal to strike. As many as four
terminations may be associated with a single culmination. Most normalfault systems …

Diverse subsidence geometries and collapse processes for ash-flow calderas are inferred to
reflect varying sizes, roof geometries, and depths of the source magma chambers, in …

Abstract Recent inference that Mesozoic Cordilleran plutons grew incrementally during> 106
yr intervals, without the presence of voluminous eruptible magma at any stage, minimizes …

Yucca Mountain is an arid site proposed for consideration as the United States' first
underground high-level radioactive waste repository. Low rainfall (approximately 170mm/yr) …

The Lípez region of southwest Bolivia is the locus of a major Neogene ignimbrite flare-up,
and yet it is the least studied portion of the Altiplano-Puna volcanic complex of the Central …

Late Miocene sills and dikes in the Paiute Ridge area of southern Nevada were emplaced in
an extensional setting beneath a small volume, alkali basaltic volcanic center. Dikes (400 …

The distribution and timing of areal basaltic volcanism are modeled using three
nonhomogeneous methods: spatio‐temporal nearest neighbor, kernel, and nearest …

We have developed a methodology for (U-Th)/He thermochronology on a variety of mineral
species. With many laboratories initiating research in the area of (U-Th)/He …

Large normal faults are corrugated. Corrugations appear to form from overlapping or en
échelon fault arrays by two breakthrough mechanisms: lateral propagation of curved fault …
