| 中文摘要: |
| 云南省羊拉铜矿江边矿段是三江成矿带中段较为典型的夕卡岩型铜矿床之一。文章在野外观测基础上,总结研究江边矿段地质特征,认为羊拉铜矿江边矿段是受地层、构造、岩浆岩体等因素综合控制的矿床,其中里农组一段(D2+3l1)夕卡岩向深部有转化为湿夕卡岩的趋势,相应的矿化将进一步增强。岩体在北侧向深部倾伏,深部与里农组一段接触部位具有形成夕卡岩型矿体的前景。综合分析认为江边段地层、构造、岩浆岩与里农段类似,有类似块状硫化物矿体形成的可能性,并指出岩体西北侧及北延具找矿前景。 |
| 英文摘要: |
| The Jiangbian section of Yangla copper deposit is one of typical skarn type copper deposit in middle of Sanjiang metallogenic belt. On the basis of field investigation, the geological characteristics of Jiangbian section of Yangla copper deposit was summarized, it is supposed that the Jiangbian deposit is jointly controled by stratum, structure and magmatic body etc.. Among them, the skarn located in the first member of Linong formation (D2+3l1) tends to transfored into wet skarn, and correspondingly the copper mineralization tends to enhance. In the northern part, the magmatic body plunges to depth, and there is great prospecting potential in the contact zone between the magmatic body and Linong formation in the depth.The comprehensive analysis result shows that the metallogenic conditions of stratum, structure and magmatic rocks in the Jiangbian section are quite similar to that in the Linong section, there is great possibility of forming massive sulfide copper orebody. Finaly, it is proposed that there is prospect potential in the northwestern part and northern part of Jiangbian magmatic body. |
