| 摘 要： | 泰国普龙矽卡岩铜金矿床是琅勃拉邦-黎府铜金多金属成矿带内一个大型矽卡岩铜金矿床。为了厘定普龙矽卡岩型铜金矿床成岩成矿时代、探讨其矿床成因,本文开展了与矽卡岩化密切相关的闪长岩锆石LA-ICP-MS U-Pb年代学研究。研究表明,普龙铜金矿成矿时代为240.6±1.2Ma,与闪长岩结晶年龄一致。结合前人研究成果,认为琅勃拉邦-黎府铜金多金属成矿带在晚二叠世—早三叠世发生了一次重要的斑岩-矽卡岩-热液铜金成矿事件。

| Abstract: | The Phu Lon skarn-type copper-gold deposit is one of the large-sized skarn-type copper-gold deposits in the northern Luang Prabang-Loei copper-gold polymetallic metallogenic belt in Thailand. The LA-ICP-MS zircon U-Pb isotopic dating give a weighted average age of 240.6±1.2 Ma for the formation of the diorites associated with the skarnization within this copper-gold deposit. This age should represent the mineralization age of the Phu Lon copper-gold deposit, i. e., the Middle to Late Triassic. The Luang Prabang-Loei copper-gold polymetallic metallogenic belt once recorded an important porphyry-skarn-hydrothermal copper-gold mineralization event during the Late Permian to the Early Triassic. |
