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。It is believed that three northeast - striking dextral slip fault zones, i. e. the baxian - shulu - handan fault zone, the huanghua - dezhou - dongming fault zone, and the linyi - huanghekou fault zone, are the result of the tectonic transform of paleogene extending to neogene - quaternary laterally slipping of north china plain rift systems, which extend along the central axis of rifts and accord with the quaternary centers of subsidence as the main seismic structures within the rifts
認為壩縣束鹿邯鄲斷裂帶、唐山河間磁縣斷裂帶和黃驊德州東明斷裂帶3條北東向右旋走滑斷裂帶為華北平原裂谷系從早第三紀伸展拉張作用進入晚第三紀第四紀走滑剪切拉張作用的產物，這3條斷裂帶分別位於3個北東向坳陷帶中部，並構成了第四紀沉降中心，與營口濰坊斷裂帶起構成華北平原內的主要強震構造。According to the analysis of the structure deformation variant direction the structure superposition during late period, and the tectonic stress field and deformation variant field, the cover extended nearly sn direction in early stage ( d - c ), maybe changed the direction in pernian ( especial the late permian ), and developed some new half - graben along sn direction except the succession activity at great fault zone. the direction of compression deformation variant, however, was nearly sn direction in indo - chinese epoch, ne - sw direction in early yanshan movement epoch, nne - ssw direction in late yanshan movement epoch, and transformed from ew to sn direction in himalayan movement epoch
根據不同構造層中變形方向及後期構造疊加的分析，對本區的構造應力場及變形場進行了探討，本區蓋層早期階段（ d - c ）為近南北向的伸展拉張，二疊紀（特別是晚二疊世）的伸展方向可能發生了改變，除在各斷裂帶繼承性活動外，沿南北方向又新生了一些半地塹。而在擠壓變形時，印支期主要為近南北向擠壓，燕山早期為nw - se向擠壓，燕山晚期為nne - ssw向擠壓，而喜山運動可能經歷了從ew向向sn向方向擠壓的轉變。
