| 摘 要： | 西藏古堆地区地处特提斯―喜马拉雅构造域一级构造单元之喜马拉雅片的中段,北涉雅鲁藏布江板块结合带。区内成矿条件较好,本文在前人成果资料的基础上,利用"矿床位置预测系统(DPIS)"中的信息量计算法,筛选了六大类38个标志信息进行信息量计算,圈出了信息总量异常区,再通过地质资料的综合分析,进行成矿远景区的圈定,取得了较好的效果。

| Abstract: | Gudui area of Tibet is located in the middle section of Himalayan flake which is one of the primary tectonic units of Tethys-Himalaya Tectonic Domain.The area adjoins the Yarlung Zangbo River Plate Junc-tion on the north and it has favorable minerogenetic conditions.Based on previous works of predecessors, this paper calculated the information content based on 38 selected clue information of 6 categories and blocked out areas of information content anomaly by applying the information content computation method of Deposit Position Indicating System (DPIS).And then through comprehensive analysis on the geologic data,the pa-per also achieved good results in delineating the metallogenic prospect area. |
