By analyzing the study area mainly tectonic belt in the southeast, rudiment structure of Lower Paleozoic era was formed in the late of Middle Ordovician, finalize structure was formed in the Late Ordovician to Silurian period, the west and the north of the southeast was superposed and reformed by Himalayas and Variscan period tectonic. Survey region can be divided into 4 region composed of seven different structural style, dividing line respectively are TZ1 structural belt-well TZ5-38 Tangbei-Yubei structural belt, and south margin fault of the Tangzhong uplift. Tempestuously reform spread unit margin, inter reform are week deformation towards the basin gradually weakened. The strongest in Tanggubasi sag, consisted of arc thrust-folds belts involved basement and towards the basin. Tanggubasi sag was depression before Ordovician, came true fold uplift since late of Ordovician to Silurian. The Tazhong uplift by Tanggubasi sag to the south is compound fold, was formed in late of Middle Ordovician, was loss of Middle Ordovician and controlled deposition of isolate platform in Lianglitage group of Late Ordovician, finalize shape was formed in Late Ordovician-Silurian. The belts are consist of wrench and thrust styles, was controlled by the north faults which thrusts intensity toward east, symmetrical compound fold in west, thrust toward north in east. From north to south by the thrust to the shear strike-slip tectonic. East Bachu uplift and East Taxinan uplift are lift, Middle Ordovician is absent, which is similar to Tazhong uplift. strike-slip faults are main characteristic in Shuntuo area, active period are late of Middle Ordovician-Silurian period and Permian. It can be deduced this tectonic system was a result lead by tectonic dynamical from Aerjin and Kunlun see plate tectonics. It indicates by time series of the transformation system and movement of the NE faults that acting force of the plate tectonics sustain from Middle Ordovician to Silurian period. Region difference include structural styles and intension indicated that the transformation were controlled by base structure and detachment layer consist of Cambrian gypsum-mud rock strata. Multiperiodic activity of the most faults indicated that the late tectonic movement play important role, the extension of NE faults might be related Late Variscian movement.
