Preface

This CD-ROM is an updated re-release of three USGS publications on the thermal maturity of sedimentary rocks in Alaska:

Vitrinite reflectance and conodont color alteration index data from Alaska: Data to accompany the thermal-maturity map of Alaska: U.S. Geological Survey Open-File Report 92-409 (1992) version 1.1 (revised 1999)

Generalized thermal maturity map of Alaska: U.S. Geological Survey Miscellaneous Geologic Investigations Map I-2494, scale 1:2,500,000 (1996).
[Note; the TIF version of this map is 158 MB. You might consider using the .ai, .pdf, or .ps versions instead.]

Thermal evolution of sedimentary basins in Alaska: U.S. Geological Survey Bulletin 2142, 131 p. (1996).

This release allows access to digital versions of these reports and to the data underlying them. An interface built around Adobe(r) Portable Document Format (PDF) allows easy navigation around these products, whereby they may be easily viewed and printed. In addition to the PDF files, data are provided in Microsoft(r) Excel format to allow manipulations in a spreadsheet program, and in ASCII format for export to more sophisticated database-management or other software. The "Generalized Thermal Maturity Map of Alaska" was produced using Environmental Systems Research Institute's ARC/INFO(r) Geographic Information System (GIS), and this CD-ROM includes the entire workspace needed to export these databases for use with ARC/INFO or other GIS software supporting the ARC/INFO format. In addition, industry-standard shapefiles are included to allow export to other GIS software.

To view PDF files in this report, you will need Adobe Acrobat Reader.
