摘要
砂宝斯金矿床位于额尔古纳隆起的北东端,上黑龙江断陷盆地的边缘,为得尔布干成矿带东北段的老沟—二根河成矿带。砂宝斯金矿床圈定工业矿体5条,金矿化体均赋存于侏罗系中统二十二站组(J2er)地层中,受SN和NNW向断裂控制。矿石自然类型为蚀变砂岩型金矿石,蚀变为硅化、碳酸盐化、绢云母化等。金品位1.00×10-6-19.57×10-6。矿床成因类型为中低温热液型矿床。Ⅱ-1号矿体的深部找矿前景较好。
The Shabaoshi gold deposit is located in northearth of the Erguna uplift and the side of the upper Heilongjiang depression. The Shabaoshi gold deposit occurs in Middle Jurassic land facies clasfic rock, there are 5 ore veins. The mainly ore types are the altered sandstone. Alteration includes silicification, seficitization, carbonatization. The average grade of gold is 1.00 ～ 19.57 × 10^-6. The metallogenic type belongs to the meso -epithermal altered hydrothermal solution type gold deposits,the ore bodies are controlled by SN and NNW trend fault. There is a good prospect exploration for deep of Ⅱ - 1 orebodies.
