Digital Database of the Geologic Map of the Island of Hawai‘i

By Frank A. Trusdell, Edward W. Wolfe, and Jean Morris

Introduction

This online publication (DS 144) provides the digital database for the printed map by Edward W. Wolfe and Jean Morris (I-2524-A; 1996). This digital database contains all the information used to publish U.S. Geological Survey Geologic Investigations Series I-2524-A (available only in paper form; see http://pubs.er.usgs.gov/pubs/i/i2524A). The database contains the distribution and relationships of volcanic and surficial-sedimentary deposits on the island of Hawai‘i. This dataset represents the geologic history for the five volcanoes that comprise the Island of Hawai'i. The volcanoes are Kohala, Mauna Kea, Hualalai, Mauna Loa and Kīlauea.

This database of the geologic map contributes to understanding the geologic history of the Island of Hawai‘i and provides the basis for understanding long-term volcanic processes in an intra-plate ocean island volcanic system. In addition the database also serves as a basis for producing volcanic hazards assessment for the island of Hawai‘i. Furthermore it serves as a base layer to be used for interdisciplinary research.

This online publication consists of a digital database of the geologic map, an explanatory pamphlet, description of map units, correlation of map units diagram, and images for plotting. Geologic mapping was compiled at a scale of 1:100,000 for the entire mapping area. The geologic mapping was compiled as a digital geologic database in ArcInfo GIS format.

DATA

This digital database was compiled with ArcInfo and consists of files in ArcInfo coverage format and export formats. ArcInfo-compatible GIS software is therefore required to use the files of this database. The database is stored in a single zipped folder (bimp.zip) in this release for ease of transfer. The scale of the source map limits the spatial resolution (scale) of the database to 1:100,000 or smaller. Available ArcInfo coverages described below:

bimp.zip: compressed file containing the following digital database files (9.4-MB file that opens into a 32.4-MB folder)

bimpgeo---Faults, contacts, and rock units (line, polygon);
bimpvent---Volcanic vents (points);
bimpcrks---Ground cracks, and fissure vents (line);
bimp_tephra---Ash distribution (line, polygon);
bimpc14---Radiocarbon sample locations and radiometric age (points);
bimpchem---Geochemical sample locations (point);
bimp_flts---Faults (line).
Miscellaneous layer and legend files to symbolize the coverages.
A database file containing major element oxide abundances for geochemical samples (bimpchem) is provided in bimpchem_tbl.dbf.
