SYSTEM REQUIREMENTS The data and text on this CD-ROM require either an IBM or compatible personal computer or a Macintosh or compatible computer. The PC should have a 486 or higher processor (Pentium or higher recommended), Microsoft(R) Windows(TM) 3.1 or higher (Windows 95 or higher or Windows NT recommended and needed to use Acrobat Reader 4 and view GEOGMAP1.PDF), 32 megabytes RAM (64 MB recommended), a VGA or SVGA color monitor that can display 256 colors, and a CD-ROM drive. The Macintosh should have a 68020 or higher processor (PowerPC needed to use Acrobat Reader 4 and view GEOGMAP1.PDF), 8 megabytes RAM (16 MB recommended), Apple System Software version 7.0 or later (7.1.2 or later needed to use Acrobat Reader 4 and view GEOGMAP1.PDF), a 13-inch color monitor that can display 256 colors, and a CD-ROM drive. On both platforms, you will need Adobe Acrobat Reader 3.0 or higher (3.01 and 4.0 included on this disc for Macintosh and Windows) or other software that can translate PDF files. If you are using Acrobat Reader 3.01 or lower, you will need to upgrade in order to view GEOGMAP1.PDF. PORTABLE DOCUMENT FORMAT (PDF) FILES This CD-ROM contains Portable Document Format (PDF) files for viewing and searching documents. The Acrobat directory contains installers for Adobe Acrobat Reader 3.01 and 4.0 for both Windows (PC directory) and Macintosh (MAC directory). The installers are provided on this disc, or can be downloaded as the latest version of Adobe Acrobat Reader, free, via the Internet from the Adobe homepage on the World- Wide Web at http://www.adobe.com/. In order to view PDF files you will need a reader that can translate PDF files. This CD-ROM contains a full-text index (INDEX.PDX and associated files in the INDEX directory) that is for use in searching the PDF files for words or sets of words using the search tool in Acrobat Reader. Note, the search ability in Acrobat 4 was only available in the commercial ("pro") version at press time and will be available for Acrobat Reader 4.0 in the summer of 1999. If you are using Acrobat Reader 3, you will be able to view all but the large shaded-relief-map PDF file (GEOGMAP1.PDF). That map is too complex for the older PDF reader and requires Acrobat Reader 4 which supports blended fills (such as used to show depth/height information on maps) which can simplify the file contents greatly. Tip: If your copy of Acrobat Reader has "File" "Preferences" "General..." "Open Cross-Document Links In Same Window" selected, you should deselect it. This will keep the PDF documents open while you open and close other PDF files. ASSOCIATED PROJECT These materials are the results of work accomplished in the first part of a six-year project. The major scientific goals and benefits of the project are to: (1) provide a comprehensive international data base on the mineral resources of the region that is the first, extensive knowledge available in English; (2) provide major new interpretations of the origin and crustal evolution of mineralizing systems and their host rocks, thereby enabling enhanced, broad-scale tectonic reconstructions and interpretations; and (3) promote trade and scientific and technical exchanges between the North America and Northeast Asia. Data from the project are providing sound scientific data and interpretations for commercial firms, governmental agencies, universities, and individuals who are developing new ventures and studies in the project area, and for land- use planning studies that deal with both mineral potential issues. Northeast Asia has vast potential for known and undiscovered mineral deposits; however, little information existed in English in the West until publication of products from this project. Data and interpretations from the project are providing basic knowledge for major scientific, commercial, national, and international endeavours by other interested individuals and groups.
