Description:

Abstract:

This digital map database is compiled from unpublished data and new mapping by the authors and represents the general distribution of surficial and bedrock geology in the mapped area. Together with the accompanying pamphlet, it provides current information on the geologic structure and stratigraphy of the area. The database delineates map units that are identified by age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps limits the spatial resolution of the database to 1:31,680 or smaller.

Purpose:

The geologic map of Upper Clayhole Valley and vicinity covers part of the Arizona Strip north of Grand Canyon. The map is part of a cooperative U.S. Geological Survey, National Park Service, and Bureau of Land Management project to provide geologic information for areas within the newly established Grand Canyon-Parashant National Monument. This map fills in one of the remaining areas where uniform quality geologic mapping was needed. The geologic information will be useful for future resource management studies for federal, state, and private agencies.

Access_Constraints: None
Use_Constraints:

Uses of this digital geologic map should not violate the spatial resolution of the map area (1:31,680) even though the digital data form removes the constraint of scale on a paper map. The accuracy inherent in map scale is also present in digital format. At a scale larger than 1:31,680, higher resolution data is not available and will not yield greater real detail. Where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.
Any hardcopies utilizing these datasets shall clearly indicate their source. If users modify the data in any way they are obligated to describe the types of modifications they have performed. User specifically agrees not to misrepresent these datasets, nor to imply that changes they made were approved by the U.S. Geological Survey.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

This report has undergone two scientific peer reviews, one digital database review, one review for conformity with geologic names policy, and review of the plotfiles for conformity with USGS map standards.

Logical_Consistency_Report:

Polygon and chain-node topology present. Polygons internal to the map boundary are completely enclosed by line segments which are themselves a set of sequentially numbered coordinate pairs. Point data are represented by coordinate pairs. The neatline was mathematically generated from latitude and longitude values.

Completeness_Report:

The geologic map and digital database of Clayhole Valley is designed to describe completely the surficial and bedrock geology at a 1:31,680 scale. Geologic information only mappable at a larger scale has been omitted. All geospatial database elements are attributed.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Well-located data are intended to have a positional accuracy within .5 mm at a 1:31,680 map scale, or 16 meters on the ground.

Lineage:

Process_Step:

Process_Description:

This map was produced using 1:24,000-scale 1976 infrared aerial photographs followed by extensive field checking. Volcanic rocks were mapped as separate units when identified on aerial photographs as mappable and distinctly separate units associated with one or more pyroclastic cones and flows. Many of the Quaternary alluvial deposits that have similar lithology but different geomorphic characteristics were mapped almost entirely by photogeologic methods. Stratigraphic position and amount of erosional degradation were used to determine relative ages of alluvial deposits having similar lithologies. Each map unit and structure was investigated in detail in the field to ensure accuracy of description.

Process_Step:

Process_Description:

Punch-registered mylar sheets were scanned at the Flagstaff Field Center on an Optronics 5040 raster scanner at a resolution of 50 microns (508 dpi). The scans were output in TIFF format and converted to ARC/INFO grids. The grids were registered and rectified to four latitude/longitude registration points.

Process_Step:

Process_Description:

The linework was vectorized using gridline. The lines were edited and attributed in ARC/INFO. Polygons were built and attributed in ARC/INFO. Point data were digitized onscreen in ARC/INFO.

Overview_Description:

Entity_and_Attribute_Overview:

The Geologic Map of Upper Clayhole Valley and Vicinity, Mohave County, Northwestern Arizona includes four geospatial datasets as ARC/INFO coverages: cv_poly (geology), cv_fold (folds, basalt flow lines), cv_dip (point data including strike and dip, collapse features, sinkholes, and volcanic vents), and cv_anno (annotation and geologic unit labels). Geospatial entities in ARC/INFO coverages have the following software-defined attributes: <cover>.pat contains AREA, PERIMETER, COVER#, and COVER-ID; <cover>.aat contains FNODE#, TNODE#, LPOLY#, RPOLY#, LENGTH, COVER#, and COVER-ID. User-defined attributes are described in detail below.
(1) The coverage cv_poly includes the following feature attribute tables: (a) a polygon feature attribute table (cv_poly.pat) that describes the geospatial distribution of surficial units represented in the Postscript (.eps) and Portable Document Format (.pdf) plotfiles of the map. (b) an arc feature attribute table (cv_poly.aat) that describes the contacts and linear features that bound rock-unit polygons. For display purposes, the cv_poly coverage includes an annotation class which contains line types and arcmarker symbols derived from the coded items LTYPE and PTTYPE respectively.
(2) The coverage cv_fold includes an arc feature attribute table (cv_fold.aat) that describes linear features (folds and basalt flow lines). For display purposes, the cv_fold coverage includes an annotation class which contains line types and arcmarker symbols derived from the coded items LTYPE and PTTYPE respectively. Arrowheads indicating plunging folds are drawn based on values in the coded item PLUNGE.
(3) The coverage cv_dip includes the following: (a) a point feature attribute table (cv_dip.pat) that describes the position of point data including strike and dips, collapse features, sinkholes, and volcanic vents. Symbols are derived from the item PTTYPE, dip angle in degrees is derived from item DIP, and strike angle in degrees is in item STRIKE. (b) cv_dip also contains annotation for dip values.
(4) The coverage cv_anno, containing subclass anno.unit, is used to annotate geologic unit labels and fault offsets. The unit labels are derived from the coded item PTYPE in the coverage cv_poly.
