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(jù)不同構(gòu)造層中變形方向及后期構(gòu)造疊加的分析,對本區(qū)的構(gòu)造應(yīng)力場及變形場進(jìn)行了探討,本區(qū)蓋層早期階段( d - c )為近南北向的伸展拉張,二疊紀(jì)(特別是晚二疊世)的伸展方向可能發(fā)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(yùn)動可能經(jīng)歷了從ew向向sn向方向擠壓的轉(zhuǎn)變。
