美国和挪威两家地质调查所正在研究一种新的地球化学符号差(Signature)系统,可用于未来的矿物勘探.美国地质调查所的地质学家J.M.保特勃尔指出,这种方法就象是指纹配比,首先,对一个已知矿区进行全面的地球化学分析,并建立该地区的一个“剖面图”;然后采用计算机处理的容易接近的数据与其它地区的地球化学剖面进行对比.若剖面相似,显然可以进行下一步的找矿工 The United States and Norway are investigating a new geochemical Signature system for future mineral exploration at the Geological Survey of the United States and Norway, according to Gemberto, a geologist at the US Geological Survey, Is the ratio of fingerprints, starting with a comprehensive geochemical analysis of a known mine area and establishing a “profile” of the area; then using computer-processed, readily accessible data for comparison with geochemical profiles from other areas If the profiles are similar, it is clear that the next step for miners can be made
