Landscape Evolution at an Active Plate Margin edited and compiled by David R. Jessey and Robert E. Reynolds Desert Studies Consortium, California State University, Fullerton and LSA Associates, Inc., Riverside, CA April, 2009 In Memoriam This volume is dedicated to Bobbe Adams who, along with her late husband Bob, helped found the Mojave Desert Quaternary Research Conference that has evolved into the Desert Research Symposium. Bob and Bobbe’s influence continues through the schol- arship they established for the best student paper presented at each year’s symposium. Bobbe also donated her husband’s geologic field notes, maps, and photographs to the Mojave River Valley Museum in Barstow, where they are available for research.

    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.

    Stratigraphy and Geochemistry of Volcanic Rocks in the Lava Mountains, California: Implications for the Miocene Development of the Garlock Fault

    Geological Society of America Memoir 195 2002 Stratigraphy and geochemistry of volcanic rocks in the Lava Mountains, California: Implications for the Miocene development of the Garlock fault Eugene I. Smith Alexander Sa´nchez Deborah L. Keenan Department of Geoscience, University of Nevada, Las Vegas, Nevada 89154-4010, USA Francis C. Monastero Geothermal Program Office, Naval Air Weapons Station, China Lake, California 93555-6001, USA ABSTRACT Volcanism in the Lava Mountains occurred between 11.7 and 5.8 Ma and was contemporaneous with sinistral motion on the Garlock fault. Volcanic rocks, equiv- alent in age and chemistry to those in the Lava Mountains, crop out 40 km to the southwest in the El Paso Mountains across the Garlock fault. Three chemical groups of volcanic rocks erupted in the Lava Mountains over a period of 5 m.y. These are (1) andesite of Summit Diggings, Almond Mountain volcanic section, and Lava Moun- tains Andesite, (2) basalt of Teagle Wash, and (3) tuffs in the northeastern Lava Moun- tains and dacite in the Summit Range. Volcanic rocks of each group have distinctive chemical signatures useful for correlation of units across the Garlock fault. Our work demonstrated that tuffs in the Almond Mountain volcanic section may be equivalent to a tuff in member 5 of the Miocene Dove Spring Formation, El Paso Mountains. The basalt of Teagle Wash probably correlates with basalt flows in member 4, and tuffs in the northeast Lava Mountains may be equivalent to tuff of member 2. Cor- relation of these units across the Garlock fault implies that the Lava Mountains were situated south of the El Paso Mountains between 10.3 and 11.6 Ma and that 32–40 km of offset occurred on the Garlock fault in ϳ10.4 m.y., resulting in a displacement rate of 3.1 to 3.8 mm/yr.

    DATING TECHNIQUES 3 Schultz's definition (1937, p.79) of the Coso should be clarified because the lava flows in the Coso Range have a wide age range. We believe that the lava flows referred to by Schultz are the rhyodacite flows on the Haiwee Ridge (fig. 1) described in the section on Pliocene rhyodacite lava flows. Parts of the Coso Formation have been described by Hopper (1947), Power (1959, 1961), Bacon and Duffield (1978), Duffield, Bacon, and Roquemore (1979), Duffield, Bacon, and Dalrymple (1980), and Giovannetti (1979a, b). Deposits mapped as the Coso (fig. 1) Occur in the Haiwee Reservoir (Stinson, 1977a), Keeler (Stinson, 1977b), and Darwin (Hall and MacKevett, 1962) 15-minute quadrangles and have been mapped in the Coso volcanic field (Duffield and Bacon, 1981). Potassium-argon dating of volcanic rocks intercalated with, and overlying, the Coso Formation has been used by Evernden, Savage, Curtis, and James (1964), Bacon, Giovannetti, Duffield, and Dalrymple (1979), and Duffield, Bacon, and Dalrymple (1980) to constrain the age of the Coso. In this report, we review these potassium-argon ages and present additional data that provide more accurate limits on the age of the Coso Formation. ACKNOWLEDGMENTS We thank C. A. Repenning for advice on paleontologic aspects of this study. G. R. Roquemore contributed valuable observations offieldrela- tions of pyroclastic rocks near Sugar Loaf. J. Metz painstakingly prepared and analyzed glass fractions of tuffs. C. E. Meyer and M. J. Woodward kindly determined fission-track ages of zircons.

Stirewalt Stephen R. Young Kenneth D. Mahrer Center for Nuclear Waste Regulatory Analyses San Antonio, Texas September 1992 ABSTRACT The long-range goal of the Volcanism Research Project is to assess likelihood of volcanic and magmatic activity in the Yucca Mountain area and the potential for disruption of a repository at Yucca Mountain by that activity. To this end, this report discusses extent of available volcanic and tectonic data for the Basin and Range Physiographic Province, assesses usefulness of these data for constraining conceptual models of tectonism and associated volcanism in the Basin and Range, and addresses use of nonlinear dynamics for analyzing patterns of volcanism. Based on data from review of existing literature, the following conclusions and recommendations are drawn to provide guidance for future work in the remaining tasks of this project: (i) middle to late Cenozoic (i.e., less than 55 million years ago) volcanism in the Basin and Range Province can be broadly correlated

    2021 Magazine

    July 2021 Welcome to the July 2021 edition of BADWATER® Magazine! We are AdventureCORPS®, producers of ultra-endurance sports events and adventure travel across the globe, and the force behind the BADWATER® brand. This magazine celebrates the entire world-wide Badwater® / AdventureCORPS® series of races, all the Badwater Services, Gear, Drinks, and Clothing, and what we like to call the Badwater Family and the Badwater Way of Life. Adventure is our way of life, so – after the sad and disastrous 2020 when we were not able to host any of our life-changing events – we are pleased to be fully back in action in 2021! Well, make that almost fully: Due to pandemic travel bans still in place, international participation in our USA-based events is not where we want it and that’s really unfortunate. Badwater 135 is the de facto Olympics of Ultrarunning and the 135-Mile World Championship, so we always want as many nationalities represented as possible. (The inside front cover of this magazine celebrates all sixty-one nationalities which have been represented on the Badwater 135 start line over the years.) Our new six-day stage race across Armenia – Artsakh Ultra – will have to wait yet another year to debut in 2022, two years later than planned. But it will be incredible, the ultimate stage race with six days of world-class trail running through several millennia of incredible culture and history, and across the most dramatic and awe-inspiring landscapes. This year, we are super excited to have brought two virtual races to life, first for the 31 days of January, and then for 16 days in April.

    The Archaeology of the Prussian Crusade

    Downloaded by [University of Wisconsin - Madison] at 05:00 18 January 2017 THE ARCHAEOLOGY OF THE PRUSSIAN CRUSADE The Archaeology of the Prussian Crusade explores the archaeology and material culture of the Crusade against the Prussian tribes in the thirteenth century, and the subsequent society created by the Teutonic Order that lasted into the six- teenth century. It provides the first synthesis of the material culture of a unique crusading society created in the south-eastern Baltic region over the course of the thirteenth century. It encompasses the full range of archaeological data, from standing buildings through to artefacts and ecofacts, integrated with writ- ten and artistic sources. The work is sub-divided into broadly chronological themes, beginning with a historical outline, exploring the settlements, castles, towns and landscapes of the Teutonic Order’s theocratic state and concluding with the role of the reconstructed and ruined monuments of medieval Prussia in the modern world in the context of modern Polish culture. This is the first work on the archaeology of medieval Prussia in any lan- guage, and is intended as a comprehensive introduction to a period and area of growing interest. This book represents an important contribution to promot- ing international awareness of the cultural heritage of the Baltic region, which has been rapidly increasing over the last few decades.
