东洞沟金矿位于党河南山金成矿带上,是由断裂构造控制的岩浆热液型金矿。中奥陶统砂岩是本区金成矿的地层条件。断裂构造及由其形成的蚀变破碎带控制着区内金矿体的形态、产状及延伸,是区内金的导矿和容矿构造。东洞沟金矿的矿体多分布在志留纪的闪长玢岩、石英闪长岩和中奥陶统砂岩的接触带上,岩体既提供了热源,也提供了部分矿质,对东洞沟金矿的形成起重要作用。
Dongdonggou gold deposit is located in the party Henan gold metallogenic belt, is controlled by the fault structure magmatic hydrothermal gold mine. The Middle Ordovician sandstone is the stratigraphic condition of gold mineralization in this area. The fault structure and the alteration and crushing zone formed by it control the shape, occurrence and extension of the gold ore body in the area, which is the gold ore-bearing and ore-hosting structure in the area. The ore bodies of the Dongdougou gold deposit are mostly distributed in the contact zone of the diorite, quartz diorite and middle Ordovician sandstone of the Silurian. The rock mass provides not only heat source but also part of the mineral, The formation of Donggou gold mine plays an important role.
