位于环太平洋锡矿带西段和特堤斯—马来亚锡矿带近交汇部位的云南锡矿床,成群成带分块集中于特定的构造—(花岗岩)岩浆带。锡矿化常伴铜铅锌钨铍等矿化(多有带状矿化特征),形成以锡为主的锡多金属矿床,以锡石硫化物矿系为主、锡石石英矿系次之;多伴有磁铁矿、磁黄铁矿等磁性矿物。云南重点锡矿区带遥感信息的地质矿产印证研究表明:锡矿成矿带对应于线性影像伴环形影像组成的线性—环形影像带,如滇
The Yunnan tin deposit, located in the western part of the Pacific Rim tin-belt and the junction of the Tethys-Malayan tin deposit, is concentrated in specific tectono- (granite) magmatic belt. Tin mineralization often accompanied with copper, lead, lead, tungsten, tungsten, beryllium and other mineralization (with belt mineralization characteristics), the formation of tin-dominated tin polymetallic deposits, mainly cassiterite sulfide, cassiterite Mostly accompanied by magnetite, pyrrhotite and other magnetic minerals. The research on geology and mineral resources with key remote sensing information in Yunnan tin deposit shows that the tin ore metallogenic belt corresponds to the linear-annular image composed of linear image with ring image,
