黑龙江省二股地区响水河多金属矿地质背景及成矿条件

Two shares of Xiangshui river area of Heilongjiang Province geological background and metallogenic conditions of polymetallic ore

黑龙江省二股地区响水河多金属矿位于小兴安岭—张广才岭多金属成矿带内,属于燕山晚期花岗闪长岩与下寒武统西林群大理岩接触带附近的矽卡岩型多金属矿床。本文涉及的工作通过高精度磁法等手段对响水河地区进行研究,发现多条具有经济价值的矿段,同时还对矿床的成矿条件进行讨论,为该区域与燕山晚期中酸性及基性浅成侵入岩有关的多金属矿床的成矿模式提供了现实依据,在实际生产和理论研究方面都有着十分重要的意义。

Xiangshuihe polymetallic ore in Ergu of Heilongjiang provience is skarn polymetallic ore which is located in Lesser Khingan Rangge—Zhangguangcai Range polymetallic minerogenetic belt and near the contact zone of late Yanshan granodiorite and lower cambrain series marble. We prospected Xiangshuihe region with high precision magnetic and other methods. Finally, we found several ore block with great economic value and discussed the minerogenetic condition of them. Our work provided realistic basis on minerogenetic model of polymetallic ore related to late Yanshan intrusive rock and is of great importance in both economic and research.
