摘　　要：在晚三叠世前长期处于地台体制的雪峰山西侧地带,上三叠统和中-新生界的沉积相、物质成分、构造变动和地台构造层的构造变动反映,这里于地洼阶段发生了强烈的造山-造盆作用,造成了当今海拔反差达约千米的盆、山景观。这类地洼型造山-造盆作用具有多种运动方式。In the area of the west side of the Xuefengshan mountains there occurred a p latform system for a long time before late Triassic.The s edimentation facies,material comp osition and structural event of the upper Triassic and Meso-Cenozoic,a nd the platform structural layer indicate that an intense orogeny-basin-making process had happened in diwa (depression)stage in this area.As a result,there appears a land-scape of basin and mountain,and their hight deviation is about up to 1000m .Obviously,the oroge-ny-basin-making process of the type of diwa (depression)has various patterns of movement.
