Silicic tuffs infilling an ancient submarine caldera, at Mineral King in California, show microscopic fabrics indicative of welding glass shards and pumice temperatures >500 degrees C. The occurrence indicates that subaqueous explosive eruption emplacement pyroclastic materials can occur without substantial admixture the ambient water, which would cause chilling. Intracaldera progressive aggradation ash from a thick, fast-moving flow occurred during short-lived approximately 26 cubic...

Abstract We reject the notion of a Jurassic continental arc in eastern Mexico, termed “Nazas arc,” on geologic grounds. Instead, we propose that SW Cordilleran U.S. and northern Sonora, passed southward into oceanic realm is represented by volcanic plutonic rocks fringed Mexican paleo-Pacific margin, which are currently found western Peninsular Ranges southern California, USA, Baja Vizcaino Peninsula mainland Mexico. To show this, present summary features arc, using geology end Arizona...
K 2 O contents have long been recognized as a potential indicator of tectonic processes, and in the Sierra Nevada, California, high-K volcanism has attributed to lithosphere root delamination. However, new data from central suggest very different control: concentrations can be explained by variations degree partial melting mantle, where volcanics are derived low-degree melts mantle lithosphere. Field evidence further suggests that pulse there was synchronous with development pull-apart...
The Sierra Nevada of California is the longest and tallest mountain range in co-terminus USA, has long been regarded as topographically very young ( < 6 Ma); however, recent work provided evidence that old (>80 Ma), represents western shoulder a Tibetan-like plateau (the Nevadaplano) was centred over Nevada. A great deal effort invested applying modern laboratory geophysical techniques to understanding Nevada, yet some most unambiguous constraints on Sierran landscape evolution are derived...
The Walker Lane belt of eastern California and western Nevada is the northernmost extension Gulf transtensional rift, where process continental rupture has not yet been completed, rift initiation can be studied on land. GPS earthquake focal mechanism studies demonstrate that currently accommodates NW-SE–directed movement between Sierra microplate North American plate, but timing nature remains unclear. I present a model for plate-margin-scale rifts at ca. 12 Ma; localization rifting in both...

The is dominated series basaltic dacitic seamount chains up ~100-km roughly perpendicular front. Dredge samples from these are geochemically distinct front rocks, and undertaken this asymmetry. Site U1437 lies an ~20-km-wide...
Abstract The ∼50 km long Rosario segment of the Cretaceous Alisitos oceanic arc terrane provides undeformed three-dimensional exposures upper 7 an extensional arc, where crustal generation processes are recorded in both volcanic and underlying plutonic rocks. These exceptional allow for study physical chemical links between rock units help constrain differentiation active during growth evolution crust. This focuses on southern third segment, previously referred to as volcano-bounded basin,...

This interpretation is based on construction detailed photomosaic, mapping three-dimensional facies distributions, measurement representative sections, collection new...
Long-lived intra-oceanic arcs of Izu-Bonin-Marianas (IBM)-type are built on thick, granodioritic crust formed in the absence pre-existing continental crust. International Ocean Discovery Program Expedition 350, Site U1437, explored IBM rear arc to better understand formation arcs. Detailed petrochronological (U–Pb geochronology combined with trace elements, oxygen and hafnium isotopes) characterizations zircon from U1437 were carried out, taking care exclude potential contaminants by (1)...

Abstract Zircon extracted from drilled oceanic rocks is increasingly used to answer geologic questions related igneous and sedimentary sequences. Recent zircon studies using samples obtained marine drill cores revealed that drilling muds in the coring process may contaminate samples.
