  • 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.

This MPR is intended to be used as a planning tool that provides land managers with mineral resource information to develop management plans. The FRTC is part of the US Department of Navy (DON). The FRTC currently encompasses an area of 223,562 acres (ac). Figure ES.1 presents the areas involved. The FRTC consists of federal land that has been withdrawn from public use and reserved for military training and operations through the Military Lands Withdrawal Act of 1999, Public Law 106-65 (MLWA). The current withdrawal will expire in November 2021, unless Congress enacts legislation providing an extension. Withdrawal of additional lands to support DON activities in ranges B-16, B-17, B-20, and the DVTA may impact public and private lands including mining and geothermal leases, as well as access to mineral exploration and production infrastructure such as roads, pipelines, and temporary and fixed facilities. As part of the EIS process, the DON proposed three action alternatives for the land withdrawal extension and expansion for the FRTC.
