河南秋树湾斑岩体特征及其南山钼矿段外围找矿方向

The characteristics of Qiushuwan porphyry granite and the prospecting target in the outside of its Nanshan ore section

秋树湾钼(铜)矿为复合斑岩型矿床,具有极大的找矿空间。其斑岩体年龄、地质及地球化学特征与东秦岭钼矿带的金堆城、南泥湖钼矿床的斑岩体特征吻合,成矿物质主要源于岩浆。矿体的产出受岩体形态、向斜构造、岩枝插入形态等控制。找矿方向为雁来岭区斑岩体两侧岩枝的插入部位和川光厂区域向斜构造倾伏端。

Qiushuwan Mo （Cu） deposit is a composite porphyry - type one ; and there is great exploration space for it. The ages, geology and geochemical characteristics of the porphyry granite are similar to granites of Jinduicheng and Nannihu porphyry molybdenum deposits in the Eastern Qinling molybdenum belt. Its ore - forming material derived from the magma. The output of the ore bodies was controlled by the rock shape, syncline and the shape of granite branch intruding into the strata. The prospecting direction is the granite in both sides of Yanlailing porphyry, and the plunging end of the Chuanguangchang syncline.
