摘要
常福龙沟金矿区赋存于大青山三套含金建造中的渣尔泰山群中,受控于大青山深大断裂及相关的次级北东、北西和近东西断裂。大青山断裂早期以韧性剪切带为特征,晚期演化为脆性断裂和推覆构造。大青山断裂及其次级断裂的交汇处为成矿提供了运输通道和容矿空间,矿体就产于该部位。岩浆活动为成矿提供了热能和部分成矿物质。笔者在本文中论述了该矿的成矿地质条件和控矿因素,并提出了矿区外围找矿标志和找矿方向。
The Changfulonggou deposit exists in the Zhaertaishan rock group which belongs to the three sets of gold-bearing formation of Daqingshanshan. It is controlled by the Daqingshan deep big fault and its sub-faults with NE, NW and nearly EW direction. The Daqingshan fault is ductile shear zone in the early period, and turned into brittle faults and nappe in the late stag. The intersection of the Daqingshan fault and its sub-fauhs provide ore-forming feeders and ore-holding palace. And the magmatic activities provide heat energy and some mineralization materials. In this article, the authors discuss the mineralization geological conditions and the ore-control factors of this gold ore, and also provide the exploration direction around this ore for the future prospecting.
