摘要
研究表明，大厂长坡锡矿床为海底喷流热水沉积－改造型。前期海底喷流热液沉积作用，在台沟与台地过渡地带形成了矿区东部和下部的纹层条带状矿和矿源层。后期构造改造作用在构造有利部位形成了西部和上部大脉状和细（网）脉状矿。两期成矿作用复合，形成了大富矿床。
The geology of the Changpo tin ore deposit indicates that it is genetically of a submarine spouting hydrothermal sedimentary-reformed type. In the previous stage, the laminal ore and source were formed by spouting hydrothermal sedimentary in the eastern part and in the lower herizon. In the late stage, the vein and veilet ores were formed by structure-reformation in the western part and in the upper herizon. Combination of two different processing is responsible for the forming of the large-scaled deposit.
