摘要
通过在豫西南栾川地区1/20万重力低值异常上进行1/2.5万重力测量,把原低值异常分解成十余个规模不等的局部低值异常,结合地质矿产资料推测,有9个局部低值异常是在大的隐伏花岗岩基上局部埋深较浅的花岗岩体的反映,是钼铅锌银多金属矿良好的成矿靶区,目前已在3个异常上新发现隐伏矿。
Through the gravity survey（1/25 000） on the low-valued regional gravity anomaly（1/200 000） in Luanchuan County,southwestern Henan Province,the preliminary low-valued anomaly is subdivided into more than ten low-valued local anomalies with the different sizes.Combining with the geological and mineralization,it is sugviped that nine of these local anomalies reflect the existence of the subsurface granite stocks connecting to the large concealed granite pluton.Accordingly,many potential targets for searching Mo-Pb-Zn deposits are found out.And now,three hidden ore mineralization occurrences have been disclosed by recent exploration projects from above-mentioned anomalies.
