】汉南—米仓山区存在印支晚期和燕山期形成的东西向构造及喜马拉雅期形成的北东向构造。前者与秦岭造山带有关，以隆起坳陷为主，但向西与龙门山区同类构造联合成弧形。后者为斜交东西向构造的断裂、隆坳和褶皱，并与四川盆地西部和荥经地区的北东向构造相连，构成龙门山推覆构造外缘带。其深部形态可依据现今不同地段的不同层位出露的构造形态予以恢复。
The Hannan-Micangshan area has the east-west structure formed during the Indosinian and Yanshanian periods and the NE structure formed during the Himalayan period. The former is related to the Qinling orogenic belt, with the main uplift depression, but the west and the Longmenshan area have similar arc structures. The latter is composed of diagonal intersection faults and uplifts and folds, connected with the NE structure in the west of Sichuan Basin and the Yingjing area, and constitutes the outer margin of the Longmen Shan nappe structure. Its deep form can be restored according to the tectonic forms exposed by different layers in different parts of the present day.
