大松坡锡矿床在大地构造位置上位于腾冲地块中著名的腾冲火山区，在成矿带上位于滇西锡成矿带腾冲-梁河成矿亚带。通过对该矿床区域地质背景及特征、控矿因素、矿床成因等研究，结果表明该矿床与区域构造和燕山晚期—喜马拉雅早期岩浆活动有着密切的时空关系和成因联系，成矿物质来源于地壳深部重熔岩浆花岗岩，大松坡锡矿床属于气成高温热液云英岩型脉状矿床。%Geotectonics position of the Dasongpo tin deposit is located in the famous Tengchong volcanic area ,in Tengchong block. Dasongpo tin deposit lies in the well-known West Yunnan Sn mineralization zone as well as in Tengchong-Lianghe Sn mineralization subzone. We achieved the following results through analyzing the ore-controlling geological character of mineral deposit,the ore-controlling factors and ore deposit origin. There are close time and space relations and origin relation between the ore deposit and the graniticmagma activity of the early Ximalaya mountain time. Mineralization material originates from the deep crust molten lava granites,the ore deposit belongs to pneumatogenic high temperature hydrothermal greisen vein type deposit.
