中文摘要: |
车户沟铜钼矿区位于赤峰市市区西北56 km处, 通过野外地质勘查及综合研究发现,该矿床为中高温大型斑岩型铜钼矿床,受印支期浅成侵入岩体及隐爆角砾岩筒控制,成矿物质来源于深部,蚀变具分带性。具有矿体规模大、品位偏低、资源储量大、斑岩体和隐爆角砾岩筒复合控矿的特征。矿化显示以细脉浸染状为主,无岩性区别,该岩体和矿体具典型的隐爆性质。文章对该铜钼矿的成矿地质特征进行分析总结,希望对以后地质找矿勘查工作起到一定借鉴作用。 |
英文摘要: |
Chehugou Mo-Cu deposit is located 50km northwest of Chifeng City. through field geological survey and comprehensive study found that the deposit is of high temperature and large porphyry Mo-Cu deposit, the indo-chinese epoch hypabyssal intrusive body and cryptoexplosive breccia cylinder control, ore-forming material comes from the deep, alteration zoning sex. With large scale and low grade of ore bodies and large reserves, porphyry and cryptoexplosive breccia cylinder composite ore-controlling characteristics. Give priority to with fine vein disseminated mineralization shows that, lithologic difference, typical of the explosive nature of the rock and ore body. This paper tries to analyze the ore-forming geological characteristics of the Mo-Cu summary, hope for future geological prospecting exploration play a guiding role. |
