Burning Man Geology Black Rock Desert.Pdf
GEOLOGY OF THE BLACK ROCK DESERT By Cathy Busby Professor of Geology University of California Santa Barbara http://www.geol.ucsb.edu/faculty/busby BURNING MAN EARTH GUARDIANS PAVILION 2012 LEAVE NO TRACE Please come find me and Iʼll give you a personal tour of the posters! You are here! In one of the most amazing geologic wonderlands in the world! Fantastic rock exposure, spectacular geomorphic features, and a long history, including: 1. PreCambrian loss of our Australian neighbors by continental rifting, * 2. Paleozoic accretion of island volcanic chains like Japan (twice!), 3. Mesozoic compression and emplacement of a batholith, 4. Cenozoic stretching and volcanism, plus a mantle plume torching the base of the continent! Let’s start with what you can see on the playa and from the playa: the Neogene to Recent geology, which is the past ~23 million years (= Ma). Note: Recent = past 15,000 years http://www.terragalleria.com Then we’ll “build” the terrane you are standing on, beginning with a BILLION years ago, moving through the Paleozoic (old life, ~540-253 Ma), Mesozoic (age of dinosaurs, ~253-65 Ma)) and Cenozoic (age of mammals, ~65 -0 Ma). Neogene to Recent geology Black Rock Playa extends 100 miles, from Gerlach to the Jackson Mountains. The Black Rock Desert is divided into two arms by the Black Rock Range, and covers 1,000 square miles. Empire (south of Gerlach)has the U.S. Gypsum mine and drywall factory (brand name “Sheetrock”), and thereʼs an opal mine at base of Calico Mtns. Neogene to Recent geology BRP = The largest playa in North America “Playa” = a flat-bottomed depression, usually a dry lake bed 3,500ʼ asl in SW, 4,000ʼ asl in N Land speed record: 1997 - supersonic car, 766 MPH Runoff mainly from the Quinn River, which heads in Oregon ~150 miles north. -
Paleozoic Geology of the Dobbin Summit-Clear Creek Area, Monitor
AN ABSTRACT OF THE THESIS OF DIANE CAROL WISE for the degree of MASTER OF SCIENCE in Geology presented on August 13, 1976 Title: PALEOZOIC GEOLOGY OF THE DOBBIN SUMMIT- CLEAR CREEK AREA, MONITOR RANGE, NYiE COUNTY, NEVADA Abstract approved: Redacted for Privacy son Paleozoic limestones, dolomites, quartz arenites, and other clastic rocks were mapped in the vicinity of Dobbin Summit and Clear Creek in the central Monitor Range. Sedimentary rock units present in this area represent the shallow-shelf eastern assemblage and basin and also the basin-slope facies of the traditional limestone- clastic assemblage. The four oldest, Ordovician, units were deposited in shallow shelf environments. The Lower Ordovician Goodwin Formation is composed of about 1200 feet of calcareous shales and thin-bedded limestones. The overlying Antelope Valley Limestone is about 500 feet thick and consists of wackestones, packstones, and rare algal grainstones.The Copenhagen Formation (135 feet thick) is the highest regressive deposit of sandstone, siltstone, and limestone below the transgressive Eureka Quartzite.The Eureka is a quartz arenite 181 feet thick, with an intercalated shallow marine dolomite member. The transition from shallow to deep water conditions can be seen in the change from algal boundstones to laminated lime mud- stones in the Hanson Creek Formation (190 feet thick).The super- jacent Roberts Mountains Formation (285 feet thick) is composed of lime mudstones and allodapic beds deposited in basinal, deep water conditions.During earliest Devonian -

F I N a L Mineral Assessment Report
BLM F I N A L MINERAL ASSESSMENT REPORT Battle Mountain District Office - Nevada J A N U A R Y 2 0 1 2 This page intentionally left blank Bureau of Land Management Mineral Assessment Report SUMMARY The Bureau of Land Management (BLM) Battle Mountain District Office (BMDO) is in the process of revising the district’s Resource Management Plan (RMP). As part of the RMP revision process, the BLM is required to prepare a Mineral Assessment Report providing information regarding mineral occurrences and potential within the BMDO Planning Area (planning area). This report provides an intermediate level of detail for mineral assessment as prescribed in BLM Manual 3060 (BLM 1994). Information presented in this report will be summarized and incorporated into an Environmental Impact Statement (EIS) for the proposed RMP and into the final RMP. The geologic history of central and southern Nevada and the planning area is very complex and includes two major cycles of sedimentation (western and eastern facies sources), episodic thrust faulting, mountain building, and associated intrusive and igneous activity. More recent geologic history includes a period of crustal extension that was accompanied by bimodal (rhyolite-basalt) volcanism, large volume caldera volcanism, and basin and range block-faulting resulting in high-levels of shallow crustal heat flow. The regional and local geologic setting has been instrumental in the location of and potential for numerous economic metallic mineral deposits in the planning area, as well as development of economic geothermal resources. MINING AND MINERAL ACTIVITY IN NEVADA Mineral exploration, particularly for gold, is an ongoing enterprise in Nevada by both operators of existing mines and by other exploration companies. -

University of Nevada, Reno A Natural and Cultural History of Leonard Rockshelter, Nevada A thesis submitted in partial fulfillment of the requirements for the degree of Master of Arts in Anthropology By Sara N. Sturtz Dr. Geoffrey Smith/Thesis Advisor May, 2020 THE GRADUATE SCHOOL We recommend that the thesis prepared under our supervision by entitled be accepted in partial fulfillment of the requirements for the degree of Advisor Committee Member Graduate School Representative David W. Zeh, Ph.D., Dean Graduate School i ABSTRACT Leonard Rockshelter (LRS) is located in Pershing County, Nevada. Robert Heizer excavated the site in 1950 and reported more than 2 m of stratified deposits from which he recovered a modest assemblage of perishable and lithic artifacts. Of interest to the University of Nevada Reno’s Great Basin Paleoindian Research Unit (GBPRU) was Heizer’s discovery of obsidian flakes in deposits dated to 11,199±570 14C BP (14,900- 11,610 cal BP). This possibility of a stratified Pleistocene occupation prompted the GBPRU to return to LRS in 2018 and 2019 for additional work, which produced few artifacts but a sizeable small mammal assemblage. In this thesis, I test two hypotheses: (1) the small mammal assemblage provides a paleoenvironmental record that demonstrates changing local conditions during the Terminal Pleistocene and Holocene; and (2) the shelter contains evidence of human occupation dating to the Terminal Pleistocene. My results demonstrate that the Early Holocene and initial Middle Holocene were more mesic than later periods. They also suggest that people did not occupy LRS until the Early Holocene, after which time they periodically returned to the site. -

PART IV: THE LACUSTRINE SUBSISTENCE PATTERN IN THE DESERT WEST Lewis K. Napton University of California, Berkeley Archaeological investigation of prehistoric occupation sites located in the Great Basin region of the western United States has dis- closed a long and remarkably detailed record of cultural adaptation in surroundings that have been characterized as one of the New World's harshest environments. The ttrestrictive" aspects of the Great Basin environment have been stressed to such an extent that one has the impression that the entire region was a bone-dry desert occupied only by small groups of Indians who managed to eke out a precarious living by subsisting on an occasional antelope, deer, or mountain sheep, the seeds of various plants, or unpalatable foods such as locusts, ants, gophers, snakes and crickets obtained from the desert biome. This '"marginal" sub- sistence adaptation was the economic basis of a lifeway that seems to have been shared by many inhabitants of the Great Basin (Steward 1938), but it is apparent that the desert-adapted existence has considerable time-depth in the region, for archaeological evidence found in sites such as Danger Cave, in western Utah, conforms to the putative Great Basin economic pattern--a ceaseless struggle to survive in an extremely arid habitat that has apparently remained almost unchanged during the last ten thousand years. A rather different impression of life in the Great Basin may be obtained, however, from study of archaeological sites located in the western part of the basin. Sites excavated or investigated during the last half-century in the Humboldt and Carson Sinks in west-central Nevada give evidence of a regional subsistence pattern that was structured primarily on utilization of the resources found in and near the lakes and marshes located in the "sinks"r or catchment basins of the Carson, Walker, Truckee, and Humboldt Rivers (Fig. -
