Title:
Summary terrane, mineral deposit, and metallogenic belt maps of the Russian Far East, Alaska, and the Canadian Cordillera
Abstract:
This CD-ROM publication provides a GIS analysis of a summary terrane map, mineral deposit maps, and metallogenic belt maps for the Russian Far East, Alaska, Canadian Cordillera and adjacent offshore areas. This CD-ROM publication is one of a series of publications for a large collaborative project on the Major Mineral Deposits, Metallogenesis, and Tectonics of the Russian Far East, Alaska, and the Canadian Cordillera. This project is providing critical information for collaborators and customers on the major metalliferous mineral resources, metallogenic patterns, and crustal origin and evolution of mineralizing systems for the region. The major collaborating agencies for the project are the Russian Academy of Sciences, ROSKOMNEDRA, the Alaska Division of Geological and Geophysical Surveys, the Geological Survey of Canada, the U.S. Geological Survey, the University of Alaska, Michigan State University, and Exxon Production Research. Other Western supporters of the project are Stanford University, the Northwest Mining Association, the Alaska Miners Association, and the Society of Economic Geologists.

Why was the data set created?

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 North America and Eastern 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.

  2. How were the data generated, processed, and modified?
    (process 1 of 2)
    Several key geologic sources were used in the compilation of the map. For Alaska, the basic outcrop pattern for the map is from Beikman (1980), Gehrels and Berg (1992,1994), Barker and others (1994), Brew (1994), Moll-Stalcup and others (1994). The distribution of terranes is from Jones and others (1987), Monger and Berg (1987), and Brew (1994), with modifications by Grantz and others (1991), Worall (1991), Nokleberg and others (1994a-c), the cited references, and the Alaskan co-authors of this report. For the Canadian Cordillera, the basic outcrop pattern is from Monger and Berg (1987), Wheeler and others (1988), and Wheeler and McFeeley (1991) with modifications by the Canadian authors. For the northern part of the Russian Far East, the basic outcrop pattern is from Sosunov (1985) with modifications by the Russian authors. For the southern part of the Russian Far East,the basic outcrop pattern is from Krasny (1991) and Bazhanov and Oleinik (1986) with modifications by the Russian authors. For the offshore areas of the central and eastern north Pacific Ocean, the basic pattern is from Atwater (1989) and Atwater and Severinghaus (1989).

  3. What similar or related data should the user be aware of?

How reliable are the data; what problems remain in the data set?

  1. How well have the observations been checked?
  2. How accurate are the geographic locations?
  3. How accurate are the heights or depths?
  4. Where are the gaps in the data? What is missing?
    complete
  5. How consistent are the relationships among the observations, including topology?
    This map was a collabarative effort of many different people, agencies, and countries, but has been throughly reviewed for consistency. Significant differences exist between the representation of onshore and offshore geology. These are: (1) the offshore part of the map is depicted in a more schematic fashion than the onshore part because of more limited data and because the offshore terranes and early Cenozoic and older overlap assemblages generally are obscured by extensive late Cenozoic sedimentary cover that is not shown unless thicker than two kilometres; (2) marginal contacts of offshore Cenozoic and Cretaceous sedimentary basins do not match contacts of onshore Cenozoic and Cretaceous sedimentary units because offshore basins are limited to those regions with sediment thicknesses greater than two kilometres; and (3) for simplicity, the major onshore Cenozoic sedimentary basins are generally not defined and described separately because the onshore part of the map is designed to emphasize terranes and overlap volcanic assemblages that are crucial for both for tectonic and metallogenic analyses published elsewhere
