Abstract:
Yucca Mountain, Nye County, Nevada, has been identified as a potential site for underground storage of high-level radioactive waste. This geologic map compilation, including all of Yucca Mountain and Crater Flat, most of the Calico Hills, western Jackass Flats, Little Skull Mountain, the Striped Hills, the Skeleton Hills, and the northeastern Amargosa Desert, portrays the geologic framework for a saturated-zone hydrologic flow model of the Yucca Mountain site. Key geologic features shown on the geologic map and accompanying cross sections include: (1) exposures of Proterozoic through Devonian strata inferred to have been deformed by regional thrust faulting and folding, in the Skeleton Hills, Striped Hills, and Amargosa Desert near Big Dune; (2) folded and thrust-faulted Devonian and Mississippian strata, unconformably overlain by Miocene tuffs and lavas and cut by complex Neogene fault patterns, in the Calico Hills; (3) the Claim Canyon caldera, a segment of which is exposed north of Yucca Mountain and Crater Flat; (4) thick densely welded to nonwelded ash-flow sheets of the Miocene southwest Nevada volcanic field exposed in normal-fault-bounded blocks at Yucca Mountain; (5) upper Tertiary and Quaternary basaltic cinder cones and lava flows in Crater Flat and at southernmost Yucca Mountain; and (6) broad basins covered by Quaternary and upper Tertiary surficial deposits in Jackass Flats, Crater Flat, and the northeastern Amargosa Desert, beneath which Neogene normal and strike-slip faults are inferred to be present on the basis of geophysical data and geologic map patterns.
A regional thrust belt of late Paleozoic or Mesozoic age affected all pre-Tertiary rocks in the region; main thrust faults, not exposed in the map area, are interpreted to underlie the map area in an arcuate pattern, striking north, northeast, and east. The predominant vergence of thrust faults exposed elsewhere in the region, including the Belted Range and Specter Range thrusts, was to the east, southeast, and south. The vertical to overturned strata of the Striped Hills are hypothesized to result from successive stacking of three south- vergent thrust ramps, the lowest of which is the Specter Range thrust. The CP thrust is interpreted as a north-vergent backthrust that may have been roughly contemporaneous with the Belted Range and Specter Range thrusts.
The southwest Nevada volcanic field consists predominantly of a series of silicic tuffs and lava flows ranging in age from 15 to 8 Ma. The map area is in the southwestern quadrant of the southwest Nevada volcanic field, just south of the Timber Mountain caldera complex.
The Claim Canyon caldera, exposed in the northern part of the map area, contains thick deposits of the 12.7-Ma Tiva Canyon Tuff, along with widespread megabreccia deposits of similar age, and subordinate thick exposures of other 12.8- to 12.7-Ma Paintbrush Group rocks. An irregular, blocky fault array, which affects parts of the caldera and much of the nearby area, includes several large-displacement, steeply dipping faults that strike radially to the caldera and bound south-dipping blocks of volcanic rock.
South and southeast of the Claim Canyon caldera, in the area that includes Yucca Mountain, the Neogene fault pattern is dominated by closely spaced, north-northwest- to north- northeast-striking normal faults that lie within a north- trending graben. This 20- to 25-km-wide graben includes Crater Flat, Yucca Mountain, and Fortymile Wash, and is bounded on the east by the "gravity fault" and on the west by the Bare Mountain fault. Both of these faults separate Proterozoic and Paleozoic sedimentary rocks in their footwalls from Miocene volcanic rocks in their hanging walls.
Stratigraphic and structural relations at Yucca Mountain demonstrate that block-bounding faults were active before and during eruption of the 12.8- to 12.7-Ma Paintbrush Group, and significant motion on these faults continued until after the 11.6-Ma Rainier Mesa Tuff was deposited. North of Crater Flat, in and near the Claim Canyon caldera, most of the tilting of the volcanic section predated the 11.6-Ma Rainier Mesa Tuff. In contrast, geologic relations in central and southern Yucca Mountain indicate that much of the stratal tilting there occurred after 11.6 Ma, probably synchronous with the main pulse of vertical-axis rotation that occurred between 11.6 and 11.45 Ma.
Beneath the broad basins, such as Crater Flat, Jackass Flats, and the Amargosa Desert, faults are inferred from geophysical data. Geologic and geophysical data imply the presence of the large-offset, east-west-striking Highway 95 fault beneath surficial deposits along the northeast margin of the Amargosa Desert, directly south of Yucca Mountain and Crater Flat. The Highway 95 fault is interpreted to be downthrown to the north, with a component of dextral displacement. It juxtaposes a block of Paleozoic carbonate rock overlain by a minimal thickness of Tertiary rocks (to the south) against the Miocene volcanic section of Yucca Mountain (to the north).
Alluvial geomorphic surfaces compose the bulk of Quaternary surficial units in the Yucca Mountain region. Deposits associated with these surfaces include alluvium, colluvium, and minor eolian and debris-flow sediments. Photogeologic and field studies locally have identified subtle fault scarps that offset these surfaces, and other evidence of Quaternary fault activity.
Purpose:
This geologic map was constructed to provide the structural and stratigraphic framework for a saturated-zone groundwater model for the Yucca Mountain Project site area.

Data_Set_Credit:
Bedrock geology mapped by Christopher J. Potter, Robert P. Dickerson, Donald S. Sweetkind, Ronald M. Drake II, Christopher J. Fridrich, and Warren C. Day, 1997-1998, and compiled from data sources cited below. Surficial geology mapped by Emily M. Taylor in 1998, and compiled from data sources cited below. Geologic contacts and faults digitized by Ronald M. Drake II, Carma A. San Juan, and Emily M. Taylor.
Native_Data_Set_Environment: ARC/INFO version 8.0.2
Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Part of the database consists of newly generated data (mapped or interpreted contacts and faults) that were compiled on mylar base maps and then in AutoCAD before being imported to ARC/ INFO. Part of the database was compiled from preexisting digital data and combined in AutoCAD before being imported to ARC/INFO. Frequency tests were run on the arc and polygon labels to ensure that no features are unlabeled. The attributes have been checked by both the authors and the reviewers for agreement with published maps, unpublished field mapping, and preliminary drafted versions of the map. The attribute data in the data set should be taken as an accurate representation of the authors' geologic interpretations.
Logical_Consistency_Report:
All lines were visually inspected by the authors for proper intersections, repetition, overshoots, undershoots, and overall logical consistency. The geologic features in the map area are all described, in the view of the authors, at a consistent scale of 1:50,000. All coverages were cleaned and built in ARC/INFO ( version 8.0.2) to ensure a logical consistency that is topologically clean.
Completeness_Report:
This dataset includes only the coverages pertaining to the geologic map. Any marginalia on the printed map (explanation of map symbols, and so forth) are not included. This map was produced to be used at 1:50,000 scale. Any geologic features too small to be shown at this scale have been omitted or generalized if they are of significant importance. The smallest objects are approximately 20 meters on a side.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The estimated horizontal positional accuracy of the data is 65 meters. All data used from published and unpublished digital sources are limited by the accuracy of that data. Attempts were made to verify the accuracy of these data by comparison to published topographic data and overlap with other digital data.
