“…During Precambrian and Paleozoic time, as much as 10,000 m (32,800 ft) of these marine sediments were deposited in the NTS region (Cole, 1997). For detailed stratigraphic descriptions of these rocks see Slate et al (1999). The only occurrence of Mesozoic age rocks in the Pahute Mesa area is the Gold Meadows Stock, a granitic intrusive mass located at the eastern edge of Pahute Mesa, north of Rainier Mesa (Snyder, 1977;Gibbons et al, 1963).…”

“…It is bounded on the north by Massachusetts Mountain and the Halfpint Range, on the east by the Buried Hills, on the south by the Spotted Range, and on the west by the Wahmonie volcanic center (see Figure A- (Prothro and Drellack, 1997). In most of the Frenchman Flat area, upper Miocene to Holocene alluvium covers the older sedimentary and volcanic rocks (Slate et al, 1999). Alluvium thicknesses range from a thin veneer along the valley edges to perhaps as much as 1,158 m (3,800 ft) in north central Frenchman Flat.…”

“…Geologic units exposed at the surface in the NTS area can be categorized as approximately 40 percent alluvium-filled basins and 20 percent Paleozoic and uppermost Precambrian sedimentary rocks; the remainder is Tertiary-age volcanic rocks, and a few intrusive masses (Orkild, 1983b;Slate et al, 1999). A generalized geologic map of the NTS area is given in Figure A-5.…”

Introduction section which formerly included a description of the NTS and its environment, the NTS mission, and history of the site. The environmental description of the site was expanded to include climatology and cultural resources and was placed in a stand-alone appendix. A description of NTS missions and its history were placed in the Executive Summary. There are five major portions or divisions of the NTSER. The summary below is provided so the reader can see the overall organization and content of the report. Summary of SectionsExecutive Summary -This portion of the report is meant to provide the reader with: (1) the purpose of the NTSER, (2) the current mission and history of the NTS, (3) a description of possible radiological dose pathways to the public, (4) a description of any radiological releases, (5) the estimated radiological dose to the public resulting from site operations, (6) a description of any non-radiological releases from the site, (7) a summary of any environmental incidents of noncompliance that occurred during the year and actions taken in response to them, (8) a description of the management system used to ensure that work is conducted in compliance with environmental and public health protection, and (9) a summary of any significant environmental program or effort.Compliance Summary -The purpose of this portion (Section 1.0) of the NTSER is to: (1) present those federal, state, and local environmental regulations which govern how operations are conducted on the NTS in order to ensure that the environment and the public are protected; (2) present in tabular form a concise summary of how NTS operations complied with these regulations during the year; and (3) direct the reader to subsequent sections of this NTSER where environmental activities and programs are described in more detail. This section is divided into multiple subsections based on the type of regulations presented (e.g., water quality regulations are presented in a separate subsection from historic preservation regulations). There are a total of 12 sections within the Compliance Summary (Sections 1.1 -1.12), the last section being a list of all active environmental permits. Environmental Monitoring and Compliance Activities -This portion constitutes the main body of the NTSER.It is divided into multiple sections (Sections 2.0 -12.0) which present the reporting year's environmental compliance activities related to monitoring and protecting the public, air, water, biota, cultural resources, and sensitive species and ecosystems on the NTS. These are the sections of the NTSER which are specifically referenced in the Compliance Summary, Section 1.0 and which support the compliance determinations presented in summary tabular form in Section 1.0. They include:• Radiological and Non-Radiological Air Monitoring -presents the methods and results of monitoring radioactive air emissions and non-radioactive air emissions (e.g., other air pollutants) on the NTS which are a result of past and present NTS operations.• Radiological and Non-R...

We describe two small scoria cone volcanoes, Hidden Cone and Little Black Peak (ages between~320-390 ka), in the Southwestern Nevada Volcanic Field and discuss their eruption mechanisms and inferences about their plumbing systems. Cone-forming pyroclastic deposits are consistent with eruptive styles ranging from Strombolian to violent Strombolian, and lavas emanated from near the bases of the cones. The volcanoes are monogenetic (rather than polycyclic, as allowed by previous geomorphic interpretations). Vents at each volcano appear to coincide with pre-existing normal faults, consistent with observations at older, deeply eroded volcanoes in the region. The existence of these two volcanoes on a topographically high area (particularly Hidden Cone) provides evidence for short feeder dike lengths (~500 m at the surface). We infer that this short length reflects the small length scale of the mantle source region that was tapped to feed each volcano.
