摘　　要：元江地区大红山群由航磁异常发现。通过地面中精度磁测,详细圈定了异常。上钻验证,经岩石地球对比,发现铁铜矿(化),并发现两个优质金红石层位,成因类型为变基性火山岩型,为大红山群找矿指出新的矿种。Dahongshan formation in Yuanjiang Area was discovered by the aeromagnetic anomaly. The detailed anomaly outlining was fixed by middle-precision magnetic method in the field, sequentially the drilling verification and chemical analysis of rocks revealed the existence of the Dahongshan formation. By contrast to the Dahongshan formation in Dahongshan area, the existence of iron-copper deposit/metallogensis and two rutile deposit location of high-quality were found, the genetic type of which is the metabasite vulcanite and with which the new minerals in Dahongshan formation will be found.
