摘要
广西九毛锡矿木锡石产于元古代四堡群变质火山岩中。共生矿物有石英、绢云母、绿泥石、黄铁矿、锡石等。本文从化学成分、微量元素、结构构造、物理性质和地球化学特征等方面对木锡石进行了研究,讨论了其形成的地质地球化学环境。木锡石是锡石的形态变种,以其独特的结构构造特征反映出锡矿床成矿作用的演化和矿床形成晚期的成因特征。
Wood-tin occurs as black-brown radiating or nodular aggregates in Proterozoic metamorphic volcanic rocks in the Jiumao tin deposit, Guangxi and coexists with quartz, sericite, chlorite, pyrite and cassiterite. In this paper the chemical composition, trace elements, structure and physical properties of wood-tin have been studied and the geological-geochemical environment where this mineral was formed is also discussed.
