摘　　要：目前,老挝境内现已发现金矿床(点)132处,其中典型矿床9处,矿(化)点114处,地化异常点9处。重要金矿床有帕奔(Phapon)金矿、色奔(Sepon)铜金矿、富开(Pha Kham)铜金矿、班康(Phakam)金矿以及萨那坎(Sakay)金矿。矿床成因类型主要有低温热液型、斑岩型、矽卡岩型、石英脉型、洪积型砂金矿。按照成矿地质背景和已知矿床(点)的分布特征,划分出琅勃拉邦—南乌江、景洪—会晒、川圹—长山、万象盆地、沙玛奇赛—巴色等5个金重点成矿区,其中琅勃拉邦—南乌江成矿区、川圹—长山成矿区有较好的金矿找矿前景。结合相关地质勘探成果,对琅勃拉邦—南乌江成矿区内的帕奔(Phapon)金矿地质特征及成矿远景进行了分析,并讨论了川圹—长山成矿区内的色奔(Sepon)铜金矿、富开(Phu Kham)铜金矿的地质特征及成矿远景。在此基础上,进一步分析了景洪—会晒、万象盆地、沙玛奇赛—巴色等成矿区的金矿找矿潜力。分析结果对于该国进一步开展金矿资源找矿勘探工作有一定的借鉴价值。At present,132 gold deposit （ore spots） are found in Laos,among them,the number of typical deposit is 9, the number of ore （mineralized） spots is 114, and the number of geophysical and geo- chemical anomaly spots is 9. The important gold deposits in Laos are Paben （Phapon） gold deposit, Seben （Sepon） copper-gold deposit, Fukai （ Pha Kham） copper-gold deposit, Bankang （Phakam） gold deposit and Sanakan （Sakay） gold deposit. The deposit genesis types are mainly for low temperature hydrothermal type, porphyry type, skarn type, quartz vein type, pluvial type sand gold deposits. Based on the metallogen- ic geological background and the distribution characteristics of the known deposits （ ore spots） in Laos, the five important metallogenic potential areas such as Luang Prabang - South Wujiang, Jinghong - Huisa, Chuankuang - Changshan, Vientiane Basin, Samaqisai - Base, among them, the prospecting potential of gold deposit of Luang Prabang - South Wujiang and Chuankuang - Changshan are good. Combing with some related geological and exploration results, the geological characteristics and prospecting potential of Paben （Phapon） gold deposit in Luang Prabang - South Wujiang metallogenic area are discussed, besides that, the geological characteristics and prospecting potential of Seben （Sepon） copper-gold deposit and Fukai （ Pha Kham） copper - gold deposit of Chuankuang - Changshan metallogenic area are also analyzed in detail. Based on the above analysis results, the prospecting potential of the Jinghong - Huisa metallo- genic area, Vientiane Basin metallogenic area and Samaqisai - Base metallogenic area are studied. The above analysis results related the gold resources distribution characteristics and metallogenic potential of Laos can provide some reference for conducting the further geological prospecting and exploration work in the country.
