| 中文摘要: |
| 池沟矿区位于南秦岭礼县—柞水海西褶皱带东段,受山阳—凤镇断裂控制,矿区内发育燕山期中酸性小岩体群。铜矿体主要赋存于黑云母二长花岗岩、石英闪长岩、石英闪长玢岩及池沟组地层中,矿区内围岩蚀变强烈,分布范围较大,且具有明显的分带特征。铜矿化呈细脉状、浸染状、细脉浸染状分布,表现出典型的斑岩型铜矿特征。通过地质调查和物化探异常对池沟矿区的地质特征分析,认为该矿区找矿前景广阔。 |
| 英文摘要: |
| The Chigou deposit is located in the eastern Lixian-Zhashui Hercynian folding belt of Southern Qinling orogenic belt.Controlled by Shanyang-Fengzhen fracture zone,a group of small-sized intermediate-acid intrusives of Yanshanian periods outcropped in this area.The copper orebodies are mainly occurred in biotite monzo-granite, quartz diorite, quartz diorite porphyrite as well as the Chigou formation strata. The contry rock alteration is intensively distributed and zoned in the space.The copper mineralization occurs in the form of stringer,disseminated and veinlet-disseminated types, which indicated that the deposit has typical characteristics of porphyry type copper deposit.Based on the integrated analysis of geological characteristics,geophysical and geochemical data,the authors predicate that there is great prospecting potential in this copper deposit area. |
