Book Synopsis The 40Ar/39Ar Geochronology and Thermochronology of the Latir Volcanic Field and Associated Intrusions: Implications for Caldera-related Magmatism by : Matthew J. Zimmerer
Download or read book The 40Ar/39Ar Geochronology and Thermochronology of the Latir Volcanic Field and Associated Intrusions: Implications for Caldera-related Magmatism written by Matthew J. Zimmerer and published by . This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: After resurgent plutonism, three plutons, probably cupolas of a larger, single intrusion, were emplaced and are now exposed along the southern caldera margin. Biotite ages from the Red River, Sulfur Gulch, and Bear Canyon plutons are 24.8, 24.5, and 24.3 Ma, respectively, suggesting incremental emplacement of the larger intrusion along the southern caldera margin. K-feldspar monotonic MDD thermal histories from the individual plutons display differences of rates and timing of cooling. MDD models suggest the Red River pluton experienced a period of isothermal cooling at 300°C between 24 and 22 Ma, followed by rapid cooling at 21 Ma. One K-feldspar MDD thermal model from the Bear Canyon indicates rapid cooling at 21 Ma, but another Bear Canyon K-feldspar thermal model indicates rapid cooling at 23 Ma, followed by isothermal conditions at 200°C between 22 and 18 Ma. The unconstrained MDD thermal models suggest reheating by younger thermal events possibly related to magma emplacement.

Book Synopsis Cenozoic Volcanism in the Cascade Range and Columbia Plateau, Southern Washington and Northernmost Oregon by : D. A. Swanson
Download or read book Cenozoic Volcanism in the Cascade Range and Columbia Plateau, Southern Washington and Northernmost Oregon written by D. A. Swanson and published by American Geophysical Union. This book was released on 1989 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Field Trip Guidebooks Series, Volume 106. This guidebook is for a six-day excursion between Issaquah, Washington (east of Seattle), and Portland, Oregon, that emphasizes the Tertiary and Quaternary volcanic geology of the western Columbia Plateau and the Cascade Range of southern Washington and northern Oregon (Figures 1 and 2). The guidebook summarizes the geology of selected areas along the route and provides a brief introduction to the general volcanic history of the Columbia River Basalt Group and the southern Washington Cascades. An extensive but not exhaustive bibliography accompanies the guidebook. The road logs are designed to be self-guiding; as such, they are more complete than necessary for guided bus excursions.
Book Synopsis The Timing and Origin of Pre- and Post-Caldera Volcanism Associated with the Mesa Falls Tuff, Yellowstone Plateau Volcanic Field by : Mark E. Stelten

This book was released on 2017 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present new sanidine 40Ar/39Ar ages and paleomagnetic data for pre- and post-caldera rhyolites from the second volcanic cycle of the Yellowstone Plateau volcanic field, which culminated in the caldera-forming eruption of the Mesa Falls Tuff at ca. 1.3 Ma. These data allow for a detailed reconstruction of the eruptive history of the second volcanic cycle and provide new insights into the petrogenesis of rhyolite domes and flows erupted during this time period. 40Ar/39Ar age data for the biotite-bearing Bishop Mountain flow demonstrate that it erupted approximately 150 kyr prior to the Mesa Falls Tuff. Integrating 40Ar/39Ar ages and paleomagnetic data for the postcaldera Island Park rhyolite domes suggests that these five crystal-rich rhyolites erupted over a centuries-long time interval at 1.2905 ± 0.0020 Ma (2?). The biotite-bearing Moonshine Mountain rhyolite dome was originally thought to be the downfaulted vent dome for the pre-caldera Bishop Mountain flow due to their similar petrographic and oxygen isotope characteristics, but new 40Ar/39Ar dating suggest that it erupted near contemporaneously with the Island Park rhyolite domes at 1.2931 ± 0.0018 Ma (2?) and is a post-caldera eruption. Despite their similar eruption ages, the Island Park rhyolite domes and the Moonshine Mountain dome are chemically and petrographically distinct and are not derived from the same source. Integrating these new data with field relations and existing geochemical data, we present a petrogenetic model for the formation of the post-Mesa Falls Tuff rhyolites. Renewed influx of basaltic and/or silicic recharge magma into the crust at 1.2905 ± 0.0020 Ma led to [1] the formation of the Island Park rhyolite domes from the source region that earlier produced the Mesa Falls Tuff and [2] the formation of Moonshine Mountain dome from the source region that earlier produced the biotitebearing Bishop Mountain flow. These magmas were stored in the crust for less than a few thousand years before being erupted contemporaneously along a 30 km long, structurally controlled vent zone related to extracaldera Basin and Range faults. These data highlight the rapidity with which magma can be generated and erupted over large distances at Yellowstone.
