黑龙江省漠河县鹿角沟地区地球物理、地球化学特征及靶区预测
|
摘要
鹿角沟地区地处大兴安岭北成矿带,区内W、Mo、Au、Bi等元素的区域背景值较高,局部富集趋势明显。通过1∶1万激电测量和土壤测量,圈出激电异常4处,W、Mo、Au为主的组合异常17处,并筛选出2处重点组合异常HT-4、HT-5。综合地质条件及各类异常特征,探明地层与正长花岗岩接触带部位异常套合较好,预测并圈定出2处找矿靶区,具有很好的找矿潜力,有望实现Mo、Au、W、Bi等矿种的找矿突破,为本区进一步找矿工作指明了方向。
Lujiaogou area is located in north Great Khingan Mountains metallogenic belt. In the area,W,Mo,Au,Bi and other elements have high regional background value with obvious local enrichment trend. According to the1∶ 10 000 scale induced polarization intermediate gradient and soil geochemical survey,there are 4 IP anomalies and17 combination anomalies mainly concerning W,Mo and Au delineated. Besides,2 key combination anomalies of HT-4、HT-5 are selected. Integrating the geological conditions with the anomalons characteristics,the study proves the anomaly fitting in the contact zone of strata and syenogranite is good and 2 prospecting targets are predicted and delineated. There are great prospecting potentials and it is expected to achieve Mo,Au,W,Bi and other minerals' prospecting breakthrough. The study provides important basis for further ore prospecting work in this area.
