摘要
大口子山位于甘肃省玉门市北侧,区内大面积被第四系覆盖,基岩出露差,传统找矿方法很难取得突破。笔者为获取更多的找矿信息,在研究区选用地质、化探、遥感相结合的方法,有效筛选矿致异常,以提高找矿效果。目前在研究区已发现金矿(化)体5条,砷矿体2条,硅灰石矿体1条,钨矿(化)体4条,综合找矿效果明显。显示出该方法对浅覆盖区及基岩出露差的区域均有较好的找矿效果。
Dakouzishan area is located in the north of Yumen City,Gansu Province.Most oft he area is covered by the Quaternary system with rare bedrock outcrops.Traditional prospecting has made little breakthroughs in the area.The authors collect and integrate geological,geochemical and remote sensing data to screen ore-causing anomalies.As a result 5 gold(mineralized) bodies,2 arsenic ore bodies,1 wollastonite ore body and 4 tungsten ore(mineralized) bodies have been located.The integration method is effective for prospecting in such are with shallow cover and rare bed rock outcrops.
