**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
that 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. Consequently, data
and interpretations from the project are providing basic knowledge for
major scientific, commercial, national, and international endeavours by
other interested individuals and groups.

# 

# Customers and Collaborating Agencies

Customers for this and the prior include: (1) major mining, petroleum,
environmental, construction, investment, and information companies,
agencies, and organizations, (2) federal and state government agencies;
(3) professional organizations; (4) earth science departments at
universities; (5) news media; and (6) mineral resource, petroleum, and
information company consultants. A major international customer is the
Commerce Working Group of the Gore-Chernomydrin Commission (GCC) chaired
by Vice-President Gore (USA) and Premier Chernomydrin (Russia).

The collaborating agencies for the project are the Russian Academy of
Sciences, Mongolian Academy of Sciences, Mongolian Technical University,
the Changchun University of Earth Sciences, China, Ministry of Geology
of China, the Korean Institute of Geology, Mining, and Materials, the
Geological Survey of Japan, and the U.S. Geological Survey. Other U.S.A.
project participants are the Colorado School of Mines, University of
Alaska Fairbanks, Stanford University, and the Northwest Mining
Association, Spokane, Washington.

**Study Area and Planned Products**

The study area for the project consists of Eastern and Southern Siberia,
Mongolia, Northeastern China, South Korea, and Japan (cover figure). The
area is approximately bounded by 40° to 82° N. latitude and 80° to 146°
E. longitude.

The planned products will include: (a) detailed mineral resource tables
and location maps with data on about 2,000 lode deposits and several
hundred placer districts, based on original, cited references; (b)
regional terrane and overlap-assemblage maps and detailed explanations
that will provide the geologic setting for mineral deposits and
metallogenic belts; (c) metallogenic-belt, and resource- and
environmental-concern maps and interpretations; and (d)
metallogenic/tectonic interpretations, including a four-dimensional
time-space model depicting the crustal origin and evolution of mineral
deposits. Publications for the project will initially consist of, rapid
preliminary reports, such as this report, of new and important regional
geologic maps, map explanations, and general mineral resource tables and
maps.. Project publications will be released in both paper (USGS
publications and scientific journals), digital (floppy disk, CD-ROM, GIS
(ARC-View), and Internet/Web) formats. The various resource tables,
maps, and interpretative materials will be authored by the international
collaborators with the USGS project members serving as co-editors, and
possibly as co-authors on some interpretative articles.
