本文论述了高黎贡山—潞西地区的区域变质—混合岩化—交代花岗岩—重熔再生花岗岩的特征和成岩成矿系列。认为龙瑞地区中下寒武统公养河群中—基性火山岩是本区锡矿之矿源层,经区域变质—混合岩化、花岗岩化过程矿质活化,在有利的含矿部位富集形成工业矿体。提出锡石石英脉型矿化为本区主要锡矿类型。 This paper discusses the regional metamorphic-migmatitic-metasomatic granites-remelted granite characteristics and diagenetic mineralization series in the Gaoligongshan-Luxi area. It is concluded that the Meso-Neoproterozoic group of middle-lower Cambrian parental group in Longrui area is the source layer of the tin deposit in this area. After metamorphism-mixing rockization and mineralization in the granitization process, it is enriched in favorable ore-bearing sites Industrial ore body. Proposed quartzite vein type mineralization as the main tin type in this area.
