| 摘 要： | 九嶷山矿田锡矿产于复式花岗杂岩体内。锡矿以云英岩体型、蚀变花岗岩型为主,具有矿体厚度大、蚀变强、品位中等、矿石利用性能好等特点。本文阐述了区内成矿地质背景、主要矿床类型与特征以及成矿与构造、岩浆岩的关系,探讨了矿床的成因机制,认为区内锡成矿与岩浆岩多期多阶段演化分异和构造活动密切相关。

| Abstract: | The Jiuyishan tin orefield occurs in the Jiuyishan composite granite body. The tin orebodies dominated by greisen type and altered granite type are characterized by big thickness, strong alteration,medium tin grade and excellent metallurgical specialities. Based on probing into regional metallogenetic geological setting,main types and characteristics of the tin deposits as well as relationships between structures,granitic magmatism and mineralization,the genetic mechanism of the tin deposits was discussed. Study shows that the tin deposits are related to poly-stage magmatic evolution and tectonic activities. |
