“…The tuff is a metaluminous, compositionally zoned, welded ash-flow tuff Vogel and Aines, 1996;Mills et al, 1997). It grades from a rhyolite in its lower part to a crystal-rich (15-20% median modal total phenocryst content) trachyte with abundant sanidine (10-20%) and biotite (1-2%), common plagioclase and quartz (2-10%), and sparse clinopyroxene and sphene (<1%) in its upper part Minor et al, 1993). Samples from this study were collected from this upper part.…”

Zircon extracted from drilled oceanic rocks is increasingly used to answer geologic questions related to igneous and sedimentary sequences. Recent zircon studies using samples obtained from marine drill cores revealed that drilling muds used in the coring process may contaminate the samples. The JOIDES Resolution Science Operator of the International Ocean Discovery Program has been using two types of clays, sepiolite and attapulgite, which both have salt water viscosifier properties able to create a gel‐like slurry that carries drill cuttings out of the holes several hundred meters deep. The dominantly used drilling mud is sepiolite originating from southwestern Nevada, USA. This sepiolite contains abundant zircon crystals with U‐Pb ages ranging from 1.89 to 2889 Ma and continental trace element, δ18O, and εHf isotopic compositions. A dominant population of 11–16 Ma zircons in sepiolite drilling mud makes identification of contamination in drilled Neogene successions particularly challenging. Interpretation of zircon analyses related to ocean drilling should be cautious of zircon ages in violation of independently constrained age models and that have age populations overlapping those in the sepiolite. Because individual geochronologic and geochemical characteristics lack absolute discriminatory power, it is recommended to comprehensively analyze all dated zircon crystals from cores exposed to drill mud for trace element, δ18O, and εHf isotopic compositions. Zircon analyzed in situ (i.e., in petrographic sections) are assumed to be trustworthy.

“…The name "latite of Donovan Mountain" was fi rst used by Minor et al (1993) to describe lava fl ows at Donovan Mountain, near Beatty, Nevada. The usage was extended to include other lava fl ows of similar age (younger than the Timber Mountain Group) in the Nevada Test Site region (Minor et al, 1993).…”

The range rises from 300 m on the fl oor of Death Valley to 2550 m at the top of Grapevine Peak. This study covers the central portion of the range, extending from Titus Canyon in the south to Scotty's Castle and Grapevine Canyon in the north (Fig. 1). Geologic studies that cover adjacent or proximal areas are shown on Figure 2. Mapping was conducted at scales of 1:12,000 and 1:24,000 both on topographic base maps and on conventional and digital aerial photographs from 1996 to 2000.
