Strike-slip can be divided into two types: pressure torsion and tensional torsional, on the plane, both of their main strike-slip fault shows a thorough strike-slip fault, in profiles, the former showed positive flower structure (the thrust upward reverse fault group), the latter showed negative flower structure (the thrust upward normal fault group). They behave in the plane with the main strike-slip fault symbiotic echelon folds, echelon reverse fault(pressure torsion) and echelon normal faults (tensional torsional). Due to the changes of tectonic stress field the Complex flower structure which is made up of Positive flower structure and negative flower structure can always be seen in actual profiles. In parallel with the direction of the strike-slip fault, sometimes fault plane tendency will change, until contrary (ribbon effect); on the direction of the strike-slip fault the stress change from the extrusion / fold, reverse fault into the stretch / normal fault (dolphin effect). Strike-slip fault universally developed in volcanic basins, are important aspect of analyzing the relationship of tectonic and volcanism. Strike-slip fault system in the study area consists of the cross-cutting main fault and associated echelon structures. The main strike-slip fault are characterized by long extension on the plane, the echelon normal fault group intersected it with an acute angle which developed in the nearby area; in profiles simultaneously developed negative flower structures and positive flower structures, fault plane steeply dipping and both sides of formation thickness different sometimes. According echelon structures with an acute angle between the direction of the main fault and the layers which the fault cut, can infer this area mainly developed dextral strike-slip fault system in the Paleogene. Volcanic rocks was significantly affected by strike-slip fault zone, volcanic eruption center beaded distribution along the main fault; the maximum thickness of volcanic rocks near the main fault, thinning to both sides, mostly terminated in the secondary faults vicinity; thickness of volcanic rocks greater than 1 km away from the main fault usually 2 km range.
