摘要
商洛地区地处秦岭山脉东段南麓,区内东西向构造断裂及酸性岩浆岩发育。萤石矿化多与断裂构造、岩体关系密切。在花岗岩体中北西西、北东东、北北西、北北东向张性断裂,是寻找萤石矿的主要地段。成矿类型为构造断裂岩浆岩型萤石矿。
Shangluo region of Shaanxi province lies at the east portion in the south side of Qinling Mountains, in which tectonic fractures and acid magrnatic rocks are developed at east-west direction. Fluorite mineralization is mostly related with fractures and intrusive rocks. Predominant places for fluorite prospecting focus on tensional fractures at NWW, NEE, NNE and NNE directions in granite bodies. The type of mineralization is attributed to fractured-magmatic fluorite deposit.
