摘要
松潘—摩天岭地区是目前金矿找矿的重点地区之一。文章在广泛收集已有地质、物探、化探、遥感等资料的基础上,基于G IS建立了该区的地学空间数据库。通过成矿条件分析,选取了六大类78个标志信息,利用“矿床位置预测系统”中的信息量计算法,圈出了信息总量异常区,再结合地质、矿产及化探等资料的综合分析,进行了金矿定位预测,取得了良好的应用效果。
Songpan - Motianling area is one of the most important region for gold prospecting. Based on geology, geophysics, geochemistry and remote sensing data, geo - spatial database is established by geographic information system. Through analyses of metallogenic conditions, 78 pieces of indicative information among 6 classes are chosen. Utilizing the information computation of ＂ Deposit Position Indicating System＂, total information abnormality is contoured. Combined with geological, ore, and geochemical data, locating prognoses for gold deposit are carried out, and practical effects are satisfied.
