Chagan sag is a secondary tectonic unit in chagandelesu depression, northeastern yingen - eji ' naqi basin, and the basement of the basin is a paleozoic fold belt of continental margin or island arc at the connection region of north china plate * tarim plate and kazakstan plate, with the character of erogenic belt. in working area and its adjacent area, the forming tectonic setting of indosinian intrusion was that orogenic belt pressed strongly, intracontinental subduction ; that of early yanshan movement epoch was the stress field transferred from compression to extension meanwhile the incrassate crust of orogenic zone turned to extensional collapse ; and that of early cretaceous volcanics was that the area structure extensional collapse further more during the post period of orogenic phase
查干凹陷屬于銀根?額濟納旗盆地東北端查干德勒蘇坳陷內的一個次級構造單元，其盆地基底為古生代時期華北板塊、哈薩克斯坦板塊和塔里木板塊交接部位形成的陸緣或島弧褶皺帶，具有古生代造山帶的性質。研究區及鄰區印支期侵入巖形成於造山帶強烈擠壓陸內俯沖的構造環境；燕山早期侵入巖形成於由擠壓轉向拉伸、造山帶的增厚陸殼開始發生伸展垮塌的構造環境；早白堊世火山巖形成於造山期后進一步發生伸展垮塌的區域構造環境。This paper studys basement fold, capping fold, arc structure and magma activity in xingguo area, preseats the concept. of spinning - decollement structure in the area, and makes inquisiton of its mechaninsm of formation
