It contains 3 Arc/Info formatted coverages, distributed in Arc Interchange format, a plottable map representation of the database at 1:24,000 scale in Postscript and Adobe PDF formats, and the original map explanation pamphlet in text, Postscript, and Adobe PDF formats. Purpose: The purpose of this dataset is to archive previous geologic mapping in the area and to enable the further use, reclassification, and analysis of existing geologic map data in the area.

Although the digital form of the data removes the constraint imposed by the scale of a paper map, the detail and accuracy inherent in map scale are also present in the digital data. The fact that this database was edited at a scale of 1:24,000 means that higher resolution information is not present in the dataset. Plotting at scales larger than 1:24,000 will not yield greater real detail, although it may reveal fine-scale irregularities below the intended resolution of the database. Similarly, 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.

Dip values in the 'dip' field of the structural geology points layer that were not clearly identifiable were calculated as the NEGATIVE assumed value, and annotation values were appended with a '?' (such as if it is assumed that a dip was 37, but was not clear, -37 was entered into the dababase, and annotation of 37? was created). For instances where the dip value was absent or completely indeterminate, the value '99' was used, and no anotation was created. No positional accuracy information was prescribed to geologic contacts in the original report (such as approximate, concealed, etc), and thus all geologic contacts were attributed as well placed (certain, or solid lines) although the original nature of the contact is unknown. Logical_Consistency_Report: Geologic lines attributed as a 'contact' do not separate geologic map units of the same type, and are not considered as 'dangles'. All geologic polygons are attributed with map unit designators found in the original report. Completeness_Report: This report is intended to completely represent and describe the original publication of the surficial and bedrock materials of the map area at a scale of 1:24000. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Point, line, and polygon features were vectorized from scans of the original maps and were edited to represent the original map at a scale of 1:24,000. This includes removing unnecessary lines, and closing all polygons. All vector geometries were then transformed into UTM coordinates with an RMS error of .003 or less. No positional accuracy information was prescribed to geologic contacts in the original report (such as approximate, concealed, etc), and thus all geologic contacts were attributed as well placed (certain, or solid lines) although the original nature of the contact is unknown.

The other attributes are AREA, PERIMETER, LENGTH, FNODE#, TNODE#, LPOLY#, RPOLY#, cover#, cover-ID, SEL, and SYMB. The primary layer is the geology layer (gran-geo), which consists of both polygon features and arc features that describes map units (polygons), and depositional contacts, faults (which may or may not be polygon bounding features) and map boundaries. Map units (polygons) are described in the polygon attribute table (gran-geo.pat). The identities of the map units are recorded in the PTYPE field by map label (i.e. Ts). For a description of the map units, consult the PostScript or PDF explanation pamphlets in this report. Geologic lines (arcs) are recorded as strings of vectors and are described in the arc attribute table (gran-geo.aat). They define the boundaries of the map units, the faults, and the map boundaries. These distinctions, including the geologic identities of the unit boundaries, are recorded in the LTYPE field. Attributes for geologic lines generally follow a scheme of the type of geologic line (i.e. fault), followed by a locational and/or scientific modifier (i.e. approx. located or queried). The geologic structure layer (gran-str) consists of point features that describe geologic structures such as strike and dip of beds. Point features, typically structural measurements, are described in the point attribute table (gran- str.pat) and are used to represent locations of structural measurements such as strike and dip, and foliation. The type of structural measurement of points is attributed in the PTTYPE field, and the measurements taken at that location are attributed in the STRIKE and DIP fields. Features representing location of samples (gran-smp) discussed in the original report, are described in the point attribute table (gran-smp.pat). Attributes of features in this dataset are recorded in the PTTYPE field, and the sample number from the map is recorded in the SAMPNO field.
