%X Anticlines from ejective structure in southeast Sichuan distribute sinstral in horizontal plane and the vertical section showed as overlapping-structures beared in upper Mesozoic and lower Paleozoic.Based on the analysis of regional geology background, structural feature and exploration data, a viewpoint is advanced in this paper that the structural framework in southeast Sichuan was formed successively under the background of transition of regional stress field from tension to compresso-shear.The structural environment,the characteristic of basement and the deep-fault are control factors in their forming process. The evolutionary history could be divided into three stages as pre-folding tension,primary folding and final forming. Most of the anticlines we see today could be regarded as superimposed bodies of two-level flower-structure,and the folding mechanism contained three factors of bend folding,buck folding and shear folding.
