| 中文摘要: |
| 河南西峡县竹园铜矿脉赋存于秦岭群变质地层中,受区域韧性构造带——寨根北韧性剪切带控制,矿床的形成受多期多阶段岩浆热液的影响,表现为构造—流体成矿,成矿方式以充填作用为主。在长期构造活动过程中,成矿流体在破碎带裂隙、角砾间沉淀形成脉状矿体。区域化探资料显示,该区异常面积大,铜、金异常明显,通过分析认为该区成矿条件好,有较好的找矿前景。 |
| 英文摘要: |
| The Zhuyuan copper ore vein is hosted in the metamorphic strata of Qinling Group, which is controlled by regional ductile structural belt-the northern Zhaigen ductile shear zone. The formation of ore deposits was related to multi-phases and multi-stages magmatic hydrothermal activities, which was represented the structure-controlling and fluid-filling mineralization, and the major copper mineralization is the fluid-filling vein form. During the process of long-term tectonic activities, the vein copper orebodies were formed by the ore-forming fluid precipitation in the fracture zone cracks and among fractured breccia. The regional geochemical data shows that there is a large geochemical anomaly with apparent copper and gold anomalies. Based onthe integrated analysis, it is considered that this area has favorable ore-forming conditions and prospecting potential. |
