Brief introduction of the research subject
By taking the metallogenic zones and the known mining areas in the east Tianshan Mountains as the main experimental fields, in this research subject the various data were processed by applying the RS means, multispectral ETM data and results measured with a high-resolution spectrometer based on considering the spectral characters of hydrothermal alternation typomorphic mineral association, and a model of classifying and extracting the information about the hypo-oscillometric ore areas was developed, which can provide the technical support for delineating the large-scale mineralized alternation zones and assessing the ore-caused abnormity. The research subject was based on the multi-source RS information and the multi-source geologic, geophysical and geochemical information. After carrying out the comprehensive research, integration and analysis from multiple disciplines, an evaluation system of regional mineralization vision zones and a recognition mark system of large-scale ore-concentrated areas were developed, and the favorable gold and copper metallogenic provinces in Central Asia were predicted. The research subject can provide some new trains of thought, new methods and new technologies for the double-quick prediction and strategic evaluation of large-scale mineral resources in aspects of extracting the information about the hypo-oscillometric ore areas, recognizing the ore-concentrated areas, etc., can also provide the scientific basis for implementing the natural resources strategy in Central Asia, and the achievements are innovative and practicable.
