Based on the study of metallotect environment,it is pointed that the southeastern Yunnan Basin of late Palaeozoic- Mesozoic era belongs to a taphrogeosyncline basin.The basin is not only a gold ore- hosted space,but also a metallogenic locus.There are many horizons with high gold- bearing content in the area.Metallogensis of gold deposits are controlled by stratum,rock type,and structural deformation as well as magmatism.The coupling gradient of these gold ore- controlling factors is a key condition that gold deposits are formed,or not.According to the above analyses,the authors have established a regional metallogenic model for gold deposits,and emphasized that industral gold bodies can form only under sectors of high couplied gradient of gold ore- controlling factors. Meanwhile,the prospecting directions of gold deposits are discussed.
