MINERAL RESOURCES SURVEY AND ASSESSMENT IN THE DAXINGANLING REGION: Review and tentative ideas for the Five-Year Plan from 2005 to 2010

The Daxinganling region, including Eastern Inner Mongolia Autonomous Region, the west part of Liaoning, Jilin and Heilongjiang provinces and Xiaoxinganling area in middle-eastern Heilongjiang, is one of the 16 important metallogenic belts in China, covering an area of 1.1 million square kilometers, with favorable ore-forming conditions and great potential. China Geological Survey has carried out a series of geologic work in the region since 1999 and made considerable results. This paper reviews the progresses and achievements of the geological survey and mineral resources assessment, with a discussion of some problems remained in current work. Based on the discussion, the authors propose a suggestion for the geologic survey and assessment work during the Five-Year Plan from 2005 to 2010 to supply a basis for further geologic work in the region.
