We use tectonic subsidence patterns from wells and stratigraphic sections to describe the
mid-Miocene to present tectonic subsidence history of the Rio Grande rift. Tectonic …

Abstract New 40Ar/39Ar dates from the Jemez Mountain volcanic field (JMVF) reveal
formerly unrecognized shifts in the loci of pre-caldera volcanic centers across the northern …

The magmatic systems that feed supereruptions result from high magma supply from depth
that sustains large regions of partial melt in the shallow crust. However, many questions …

Repeated intrusions of mafic magma have long been known to be a driver of long-lived
magmatic systems. Although the importance of mafic recharge of silicic magma systems is …

Abstract The Otowi Member of the Bandelier Tuff erupted at ca. 1.60 Ma from the Valles
caldera (New Mexico, USA). It consists of as much as 400 km3 (dense rock equivalent) of …

Abstract The Jemez Mountains volcanic field (JMVF) is the site of the two voluminous,
caldera-forming members of the Bandelier Tuff, erupted at 1· 60 and 1· 25 Ma, following a …

ABSTRACT New 40Ar/39Ar results from drill-hole cuttings of basaltic and basaltic andesite
flows from the Guaje well field of the Pajarito Plateau along the western part of the Española …

Data on the evolution of magmatic plumbing systems are essential for the understanding of
magma motion in monogenetic volcanoes and associated volcanic hazard. Combined field …

Abstract The Cerro Toledo Formation (CTF), a series of intracaldera rhyolitic dome
complexes and their associated extracaldera tephras and epiclastic sedimentary deposits …
