黑龙江四平山金矿深部矿体预测

四平山热泉型金矿床成矿的地质条件和产出的大地构造背景优越,具有非常好的浅成低温热液矿床的成矿环境,其深部存在新矿体的可能性较大。本文对照该类矿床的成矿模式,结合区域地质特征及钻探和物探工程的揭露情况对矿区深部可能存在的矿体位置进行了预测,结果表明矿区148线ZK927孔和ZK914孔之间,有断层通过的电、磁异常套合部位,深度300～500m处可能有新矿体存在。

Prediction of deep orebody in Sipingshan gold deposit of Heilongjiang

The geological conditions and geotectonic background of hot spring gold deposit in Sipingshan are superiorly,with good metallogenic environment of epithermal deposit,which has the possibility of existing new orebody in its deep part. Comparing this kind of deposits,the authors forcast the position of the orebody combined with regional geological characteristics and the exposed situation of drilling and geophysical engineering. The results show that there is a overlap position of electromagnetic anomaly passed by faults between ZK927 and ZK914 pores of line 148,and the new orebody may exist in 300 ～ 500 m.
