Polygon Data from 1996 "Generalized Thermal Maturity Map of Alaska"

Summary

This dataset consists of a polygon coverage and associated attribute data derived from the onshore portion of the 1996 "Generalized Thermal Maturity Map of Alaska" compiled by M.J. Johnsson and D.G. Howell, which was published as Plate 1 in US Geological Survey Bulletin 2142: "Thermal Evolution of Sedimentary Basins in Alaska". The published map summarizes vitrinite reflectance and conodont alteration index data (both measure the thermal maturity of rocks) into generalized units that can be shown cartographically at 1:2,500,000. This digital dataset includes the 8 map units indicated on the original map. (5 thermal maturity levels; 2 rock or sediment type; 1 "no data"). The data quality of the generalized information is retained, [...]

Purpose

This coverage is intended to provide digital features (polygons) representing generalized thermal maturity units in Alaska for use in small-scale spatial analysis (statewide) with similar coverages such as geologic units,vegetation types, soils, etc.
