滇黔桂地区是近年来金矿找矿的重点、热点地区之一,并不断取得找矿突破。在广泛收集地质、物探、化探、遥感、重砂等资料的基础上,基于GIS建立了本区地学空间数据库。通过对区内控矿地质条件和成矿规律的总结,建立了该区金矿找矿预测模型,选取了地质、化探、重砂、矿产等六大类57个标志信息,运用“矿床位置预测系统(DPIS)”的信息量预测法,获得了信息量异常,结合区内成矿地质条件,圈定了找矿远景区,并对找矿远景区进行了简要的评价。
Yunnan, Guizhou and Guangxi regions are the focus of gold prospecting in recent years, one of the hot spots, and continue to obtain prospecting breakthrough. Based on the extensive collection of geological, geophysical, geochemical exploration, remote sensing, heavy sand and other data, based on GIS to establish a geo-spatial database. Through the summary of the ore-controlling geological conditions and metallogenic regularities in the area, the prediction model of gold ore prospecting in the area is established. Fifty-six signs of geological, geochemical exploration, heavy sand and mineral resources are selected and the “ Prediction System (DPIS) ”is used to predict the amount of information, and an abnormal amount of information is obtained. According to the metallogenic geological conditions in the area, the prospecting prospect area is delineated and a brief evaluation of the prospecting prospect area is made.
