“…Zircon crystallization ages suggest that the presentday low-velocity zone beneath the caldera may not necessary be a young feature related to only the last pulse of volcanism, but may instead represent a longer-lived feature that was punctuated by a brief eruption cycle between 68.3 and 74.4 ka. Furthermore, the U/Th ages of zircon are broadly similar to some U/Th ages for travertine deposits at nearby warm springs (Goff and Shevenell, 1987), suggesting that the protracted assembly and residence of the East Fork Member magma chamber may have been a significant heat source for the Valles caldera hydrothermal system.…”

a b s t r a c tNew 40 Ar/ 39 Ar and U/Th ages provide insight into the youngest eruptions at the Valles caldera and also reveal previously unknown pulses of magmatism. The youngest eruptive units, collectively termed the East Fork Member of the Valles Rhyolite, include the El Cajete pyroclastic beds and co-erupted Battleship Rock ignimbrite, and the disconformably overlying Banco Bonito lava flow. Previous attempts to date these units using a variety of techniques yielded ages ranging from b 40 ka to N 1 Ma. New 40 Ar/ 39 Ar ages were generated using the highsensitivity, multi-collector ARGUS VI mass spectrometer, which provides more than an order of magnitude increase in precision compared to most single-detector mass spectrometers. 40 Ar/ 39 Ar dating of single crystals yields a range of ages, of which the youngest populations are interpreted to represent the eruption age. Sanidine ages indicate that the El Cajete pyroclastic beds and Battleship Rock ignimbrite erupted at 74.4 ± 1.3 ka, whereas the Banco Bonito lava erupted at 68.3 ± 1.5 ka. Populations of older crystals represent variably degassed xenocrysts, explaining why previous 40 Ar/ 39 Ar bulk step-heating analyses yielded spuriously old and irreproducible results. U/Th dating of unpolished zircon surfaces also yield multiple age populations, which range from the eruption age to N350 ka, indicating protracted magmatism during the 453-ka-long eruptive hiatus prior to the eruption of the East Fork Member. 40 Ar/ 39 Ar and U/Th ages indicate that the East Fork Member represents a short (6.1 ± 2.8 ka) eruptive cycle, from a longer-lived magmatic system beneath the southern caldera. Equally short repose periods, similar to the interval between the El Cajete-Battleship Rock and Banco Bonito eruptions, are possible during future volcanism at the Valles caldera. Results demonstrate that detailed geochronology using single-crystal and in-situ techniques is necessary for understanding the eruptive history and magmatic evolution at some young volcanic systems.Published by Elsevier B.V.

“…Climate conditions (i.e., humid climate with marked increase in plant growth), for instance, have been recognized as very influential in the deposition of tufa (Harmon et al, 1979;Henning et al, 1983;Pazdur et al, 1988;Baker et al, 1993;Goudie et al, 1993;Pentecost, 1995Pentecost, , 2005Ford and Pedley, 1996;Roberts et al, 1998;Dramis et al, 1999;Soligo et al, 2002). The influence of climate conditions is, in contrast, less well-documented and understood for the case of endogenic travertines (Goff and Shevenell, 1987;Sturchio et al, 1994;Pentecost, 1995;Frank et al, 2000;Rihs et al, 2000), which are travertine deposits formed through chemical precipitation from ground-water with at least a deeply-derived significant component regardless of the water temperature (Crossey et al, 2006). It is also poorly understood how climate conditions may combine with other factors such as a high heat flow, deep fluids, and high-permeability conduits through the crust to control the formation of endogenic travertines.…”

“…However, syn-rift strata may also contain localized chemically precipitated sedimentary rocks, including (1) limestones, evaporites, and diatomites deposited in lakes and wetlands (Cohen and Thouin 1987;Liutkus and Ashley 2003;Owen et al 2004;Mack and Stout 2005), (2) calcareous tufas and travertines and siliceous sinters associated with cold or hot springs (Rimstidt and Cole 1983;Goff and Shevenell 1987;Crossey et al 2011), (3) calcite and iron and aluminum oxides and hydroxides precipitated in subsurface horizons of soils (Gile et al 1966;Mack and James 1992;Ashley and Driese 2000), and (4) authigenic calcite precipitated from shallow, meteoric groundwater (Hay and Reeder 1978;Hay et al 1986;Mack et al 2000). Although they constitute a small percentage by volume of terrestrial rift basins, chemically precipitated sedimentary rocks may provide important information about basin-scale depositional architecture, paleoclimate, and groundwater composition and flow paths.…”

Exposed in upper Pliocene fluvial strata in the eastern Rincon Hills and adjacent Jornada del Muerto Basin, southern Rio Grande rift, New Mexico, USA, are five laterally continuous beds 0.2 to 1.0 m thick of opal-CT, which straddle the East Rincon Hills normal fault. Four of these opal beds change basinward over , 1 km or less to white, friable, lithofeldspathic sand with opal glaebules, and then to microcrystalline calcite. The opal and calcite generally replaced fine sand at shallow depths, although two beds locally precipitated from standing water. 87 Sr/ 86 Sr values (0.71301 to 0.71724) of the opal beds are consistent with precipitation from an advecting, high-temperature geothermal fluid that flowed through bedrock and/or from a hightemperature geothermal fluid derived from a deep-crustal source. Carbon and oxygen isotopic values (d 13 C PDB = 27.1 to 20.6; d 18 O PDB = 29.1 to 25.6) of the calcite beds lie between and overlap those of Paleozoic carbonate and Pliocene paleosol calcite, suggesting precipitation from a mixture of a high-temperature geothermal fluid that interacted with Paleozoic carbonates and shallow, meteoric groundwater, for which paleosol calcite is a proxy. The geothermal fluids are interpreted to have upwelled along the East Rincon Hills fault, flowed laterally at or just below the surface, and precipitated opal in response to rapid cooling and evaporation. Downflow precipitation of opal glaebules occurred as a result of decreasing silica concentrations and perhaps by mixing with shallow, meteoric groundwater, from which calcite precipitated, probably by CO 2 degassing.
