摘　　要：红土型金矿常产于原生金矿或富金地质体的附近。原生金成矿带或化探异常区是寻找该类矿床的有利远景区。滇西富碱斑岩带是重要铜金多金属成矿带。根据已知矿床地质特征、岩体成矿微量元素丰度值以及该带气候特点分析，滇西富碱斑岩带不仅是重要的原生多金属成矿带，也是重要的具有很大找矿前景的次生红土型金矿的成矿远景区带。The laterite gold is generally mineralized near the primary ore or gold-rich bodies. The primary gold ore belt or geochemical anomalous region serves as an important prospect for prospecting of the lalterite gold deposits,such as the west Yunnan Cu-Au belt related to alkali porphyry belt. Based on geology,trace element abundance and climate, it is suggested that the west alkali porphyry belt is not only an important primary polymetallic ore belt,but also a prosporous laterite gold belt.
