Abstract:

The Geologic Map of Arizona was compiled at a scale of 1:500,000 by Eldred D. Wilson, Richard T. Moore and John R. Cooper, in 1969 and reprinted in 1977, 1981, and 1983.
Comparison of an acetate copy of the 1983 map with existing paper copies of earlier maps shows some updating of the original by 1983. This 1983 acetate was scanned and vectorized by Optronics Specialty Co., Inc. in 1998, and put into an Arc/Info geographic information system (GIS). The digital geologic map database can be queried in many ways to produce a variety of derivative geologic maps.

Purpose:

This database was developed to provide a GIS of the geologic map of the State of Arizona for use at a scale of 1:500,000 or smaller. This GIS is intended for use in future spatial analysis by a variety of users. The geologic unit descriptions for this map may be updated to reflect more current description of structures and the geochronology of the map units.
This database is not meant to be used or displayed at any scale larger than 1:500,000 (e.g., 1:100,000 or 1:24,000)

Supplemental_Information:

This GIS database consists of 4 Arc/Info datasets: one line and polygon file (azgeol) containing geologic contacts and structures (lines) and geologic map rock units (polygons), one line file (azfold) containing the folds and crater boundaries, one point file (azptfeat) containing geologic features, cinder cones and diatremes. one point file (azptdec) containing decorations, and

Data_Set_Credit:

Eldred D. Wilson, Richard T. Moore, and John R. Cooper compiled the geologic map of which an acetate archive copy of the separates were located in Reston VA. Robert Miller (USGS) attached fiducial tics to assure registration accuracy. Optronics Specialty Co., Inc. scanned the geologic map and provided minimally attributed Arc/Info interchange-format files to the USGS.
Douglas M. Hirschberg imported the files, transformed them to Lambert Conformal Conic, attached and attributed an interim geologic map data model, verified arc, point, and polygon attribution, added, re-positioned, or re-attributed features as needed, and assisted in creating the look-up tables.
G. Stephen Pitts assisted with the design of the data model, entered the explanatory and source text, assisted in creating the look-up tables, and wrote the metadata.

Native_Data_Set_Environment:

SunOS, 5.6, sun4u UNIX ARC/INFO version 7.2.1

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Accuracy of the Attribution was verified by manual comparison of the sources with hard copy printouts and plots.

Logical_Consistency_Report:

Polygon and chain-node topology present.
Polygons intersecting the neatline are closed along the border. Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. Line segments are a set of sequentially numbered coordinate pairs. No duplicate features exist nor duplicate points in a data string. Intersecting lines are separated into individual line segments at the point of intersection. All nodes are represented by a single coordinate pair which indicates the beginning or end of a line segment. The map boundary came from the scan, was projected to Lambert Conformal Conic.

Completeness_Report:

The digital dataset was produced from a previously published map (Wilson, Moore, & Cooper, 1969) which is considered to be a high quality cartographic product, generally speaking contacts exist where mapped, and the best available at 1:500,000. From subsequent mapping, errors are known to exist with the structure and geochronology.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

The horizontal positional accuracy for the digital data may be no better than +/- 500 meters (1 mm at mapscale). It was tested by visual comparison of the source acetate and available paper maps with hard copy plots.

Process_Step:

Process_Description:

The original separates for this map were not locatable in Menlo Park, CA, and after extensive search, thought to no longer exist. By thorough investigation, two separates, the water layer and the geologic units, were found in a map tube in Reston, VA., and forwarded to Menlo Park, CA. where Robert Miller attached Lat-Lon tics to the acetate layer of the geologic units to assure registration accuracy

Process_Date: 1998

Process_Step:

Process_Description:

The registered acetate separate of the geologic units, contacts, and structure was scanned, vectorized, minimally attributed, and exported to an Arc/Info interchange-format by Optronics Specialty Co., Inc and files were given to the USGS in Tucson

Process_Date: 1998

Process_Step:

Process_Description:

The four coverages were transformed to Lambert Conformal Conic projection using 28 tics which produced an RMS error of 0.004. All linework, points, and attributions were verified by extensively comparison between printed versions of the map, the 1983 source acetate, and hard copy plots derived from the database. Some very small polygons were not identifiable on the original printed maps or the acetate, and were eliminated. Some small polygons were missing from the initial capture, and were re-captured by D.M. Hirschberg.
All faults were attributed as Throw Unknown, Normal, Thrust, or Strike Slip, as determined from visual inspection of attributions on the paper map. Faults where attributed, were identified as U/D, T, or, in two cases on the 1983 map, with the right lateral strike slip decoration. Sense of up or down was determined by placement of the letters U and D on the paper map. Sense of upper plate, lower plate for thrust faults was inconsistent, (T on side of older rock in some cases and on side of younger rocks in other), so no upper plate / lower plate attribution was made on the Trust faults.
