摘要
芙蓉矿田锡矿体产于骑田岭复式花岗岩体中,受NE向断裂构造的控制。锡矿类型主要有云英岩型、矽卡岩型、蚀变岩体型、构造蚀变带型及构造蚀变带-矽卡岩复合型等。在阐述区域锡矿成矿地质背景的基础上,划分了成矿期次,探讨了矿床成因机理及找矿模型,认为区内锡矿成矿与岩浆岩多期多阶段演化分异和构造活动密切相关。
The Furong orefield is one the most important tin orefields. The tin orebodies is located in the Qitianling composite granite intrusion and controlled by the NE-striking structures. Tin deposits mainly include greisen type,skarn type,altered granite type,tectonoalternation type and tectonoalternation-skarn type. On the basis of expatiating regional metallogenetic geological setting,the mineralization stages are divided,origin of the deposit and prospecting model are discussed,and the authors believe that tin mineralization in the studied area is related to multi-stage evolution of granitic magma and tectonic activities.
