Description:
Abstract:
New 1:6,000-scale geologic mapping in a 20-square-kilometer area near the
south end of Yucca Mountain, Nevada, which is the proposed site of an
underground repository for the storage of high-level radioactive wastes,
substantially supplements the stratigraphic and structural data obtained
from earlier, 1:24,000-scale mapping. Principal observations and
interpretations resulting from the larger scale, more detailed nature of
the recent investigation include: (1) the thickness of the Miocene Tiva
Canyon Tuff decreases from north to south within the map area, and the
lithophysal zones within the formation have a greater lateral variability
than in areas farther north; and (2) fault relations are far more complex
than shown on previous maps, with both major (block-bounding) and minor
(intrablock) faults showing much lateral variation in (a) the number of
splays and (b) the amount, distribution, and width of anastomosing breccia
and fracture zones.
Purpose:
Provide more recent and detailed stratigraphic and structural data to the
south-central Yucca Mountain area.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Part of the database consists of newly generated data that were compiled
on mylar and then digitized in AutoCAD. Data were also collected
digitally in the field using a Personal Digital Assistant (PDA) loaded
with digital orthophoto quarter quadrangles (DOQQ). Part of the database
was compiled from preexisting digital data. All data were combined in
AutoCAD before being imported to ARC/INFO. Data were checked by the
authors and the reviewers for agreement with published maps, unpublished
field mapping, and preliminary versions of the map. This map was
thoroughly reviewed for conformity with U.S. Geological Survey editorial
standards and stratigraphic nomenclature.
Logical_Consistency_Report:
Map elements were visually checked by the authors and editor for overshoots,
undershoots, duplicate features, polygon attributes, and other errors.
Automated (ARC/INFO) routines were also used to check the databases for
polygon label errors and dangling arcs. The coverages were cleaned in
ARC/INFO to ensure logical consistency that is topologically clean. The map
was reviewed by other geologists for consistency with basic geologic
principles and general conformity to USGS mapping standards.
Completeness_Report:
This dataset is complete and includes the spatial coverages pertaining to
the geologic map. This map was produced to be used at a scale of 1:6,000.
Any geologic features too small to be shown at this scale have been omitted
or generalized.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Many geologic features were drawn digitally utilizing GPS. The
estimated horizontal positional accuracy of the data is 3 meters. All
data used from published and unpublished digital sources are limited by
the accuracy of that data.
