摘要
内蒙古中部地区中—新元古代黑色岩系发育,形成于渣尔泰-白云鄂博裂陷槽内,命名为渣尔泰群和白云鄂博群。目前,仅在白云鄂博群的黑色岩系中发现并勘查了一批原生金矿。矿石主要类型为细脉型和蚀变变质岩型。金矿受层位和构造破碎带控制,金平均品位低,可形成大型或超大型矿床。因此,内蒙古中部中—新元古代黑色岩系中金矿资源潜力大,找矿远景好。
Houcang area in Zhaoyuan city of Shandong province locates in the north of Jiaodong Peninsula. Its geo- tectonic location is Jiaobei uplift of Jiaodong uprise in North China platform. Tectonic and magmatic activities in this area are stong. Rock alteration and mineralization are very common. Two bodies have been found here and there is a good ore- forming conditions and prospecting potentiality.
