There are many large and super-large ore deposits in the southeastern Yunnan metallogenetic zone of South China metallogenetic province. In the past opinion, the genesis of them is related to the intrusion of 3 large granite bodies. However, the important witness of effusive sedimentation has been discovered in the massive sulfide ore of 3 super-large ore deposits by many research organism and people since 1980s. The trilobite fossil in the direct top and bottom rock beds of ore body Ⅵ of Bainiuchang has been discovered in the drilling hole and the sedimentary cassiterite has been discovered in the ore of Baiyang ore block, which are difficultly related with the metallogenesis of Awei blind granite body.
