The Bearhead Rhyolite, Jemez Volcanic Field, NM
Journal of Volcanology and Geothermal Research 107 32001) 241±264 www.elsevier.com/locate/jvolgeores Effusive eruptions from a large silicic magma chamber: the Bearhead Rhyolite, Jemez volcanic ®eld, NM Leigh Justet*, Terry L. Spell Department of Geosciences, University of Nevada, Las Vegas, NV, 89154-4010, USA Received 23 February 2000; accepted 6 November 2000 Abstract Large continental silicic magma systems commonly produce voluminous ignimbrites and associated caldera collapse events. Less conspicuous and relatively poorly documented are cases in which silicic magma chambers of similar size to those associated with caldera-forming events produce dominantly effusive eruptions of small-volume rhyolite domes and ¯ows. The Bearhead Rhyolite and associated Peralta Tuff Member in the Jemez volcanic ®eld, New Mexico, represent small-volume eruptions from a large silicic magma system in which no caldera-forming event occurred, and thus may have implications for the genesis and eruption of large volumes of silicic magma and the long-term evolution of continental silicic magma systems. 40Ar/39Ar dating reveals that most units mapped as Bearhead Rhyolite and Peralta Tuff 3the Main Group) were erupted during an ,540 ka interval between 7.06 and 6.52 Ma. These rocks de®ne a chemically coherent group of high-silica rhyolites that can be related by simple fractional crystallization models. Preceding the Main Group, minor amounts of unrelated trachydacite and low silica rhyolite were erupted at ,11±9 and ,8 Ma, respectively, whereas subsequent to the Main Group minor amounts of unrelated rhyolites were erupted at ,6.1 and ,1.5 Ma. The chemical coherency, apparent fractional crystallization-derived geochemical trends, large areal distribution of rhyolite domes 3,200 km2), and presence of a major hydrothermal system support the hypothesis that Main Group magmas were derived from a single, large, shallow magma chamber. -

The Friends of the Pleistocene is an informal gathering of Quaternary geologists, geomorphologists, and pedologists who meet annually in the field. The field guide has been separated into two parts. Part C (open-file report 454C) contains the three-days of road logs and stop descriptions. Part D (open-file report 454D) contains a collection of mini-papers relevant to field-trip stops. This field guide is a companion to open-file report 454A and 454B, which accompanied a field trip for the annual meeting of the Rocky Mountain/South Central Section of the Geological Society of America, held in Albuquerque in late April. -

Source Provenance of Obsidian Artifacts from Salmon Ruin, Northwest New Mexico
Department of Anthropology 232 Kroeber Hall University of California Berkeley, CA 94720-3710 SOURCE PROVENANCE OF OBSIDIAN ARTIFACTS FROM SALMON RUIN, NORTHWEST NEW MEXICO by M. Steven Shackley, Ph.D. Director Archaeological XRF Laboratory University of California, Berkeley Report Prepared for Paul Reed Center for Desert Archaeology c/o Salmon Ruins, New Mexico 5 November 2004 INTRODUCTION The raw material used to produce all ten obsidian artifacts was originally procured from one of the major sources in the Valles Caldera, Jemez Mountains, northern New Mexico approximately 154 airline km southeast. Nine of the samples were from the Valle Grande Rhyolite source, which does not erode outside the caldera and had to be originally procured from within the caldera (Shackley 2004). LABORATORY SAMPLING, ANALYSIS AND INSTRUMENTATION ANALYSIS AND INSTRUMENTATION This assemblage was analyzed on a Spectrace/Thermo QuanX energy-dispersive x-ray spectrometer at the Archaeological XRF Laboratory, Department of Earth and Planetary Sciences at the University of California, Berkeley. All samples were analyzed whole with little or no formal preparation. The results presented here are quantitative in that they are derived from “filtered” intensity values ratioed to the appropriate x-ray continuum regions through a least squares fitting formula rather than plotting the proportions of the net intensities in a ternary system (McCarthy and Schamber 1981; Schamber 1977). Or more essentially, these data through the analysis of international rock standards, allow for inter-instrument comparison with a predictable degree of certainty (Hampel 1984). The spectrometer is equipped with an electronically cooled Cu x-ray target with a 125 micron Be window, an x-ray generator that operates from 4-50 kV/0.02-2.0 mA at 0.02 increments, using an IBM PC based microprocessor and WinTraceTM reduction software. -
