| 中文摘要: |
| 三江成矿带是我国重要的多金属基地,正兴铜多金属矿区就处于三江成矿带中的有利成矿地段,为一重要的铜多金属矿找矿远景区。 通过对研究区的综合分析,该区构造活动强烈,构造迹象明显,火山活动也较发育。利用地质综合手段明确了构造的深部特征如产状、切割深度、属性等。确定了矿体赋存于普洱中轴断裂两侧的次级构造带内,受成矿机制影响矿体形态呈细脉状、条带状、透镜状、鸡窝状等。综合分析后得出该矿床成因主要为受构造与地层联合控制的构造热液蚀变型矿床。明确了构造活动对矿体完整性及形成的影响。 |
| 英文摘要: |
| Sanjiang metallogenic belt is an important multi-metal base in our country. The Xilang copper metallogenic belt is located in a favorable metallogenic area in the three rivers metallogenic belt, and it is an important copper metallogenic metallogenic ore to find a distant scenic spot. Based on the comprehensive analysis, it is indicated that the area had experienced strong tectonic and volcanic episodes with some obvious corresponding signs left. Combined with multiple geological survey methods some tectonic features in deep such as attitude, depth of cut and properties have been defined, as well as the pattern and scale of the igneous rock. It is suggested that ore bodies are mainly hosted at the secondary tectonic systems on both sides of the Central Axis Fault and occur at fine vein, banded, lenticular or nest patterns due to the impact of the mineralization mechanism. On the basis of the synthetical study, it is concluded that the deposits can be attributed to the tectonic hydrothermal alteration type which are chiefly controlled by structure and stratum. The effects of tectonic activity on the integrity and formation of ore bodies are clarified, and guidance is provided for the next ore prospecting. |
