The Jiangnan fault zone in Anhui Province distributes in NE direction along the east to Shitai, Jingxian and Xuancheng lines. The field mainly shows structural breccia fracture zone and a series of thrust nappe faults. The Bouguer gravity anomaly shows that the occurrence of deep faults gradually slows down and has the characteristics of SE migration. The lithology and sedimentary environment on both sides of the fault were controlled from Cambrian to Late Devonian. Based on the analysis and study of its field tectonic phenomena, geophysics and lithofacies palaeogeography, it is considered that the Jiangnan fault zone （Anhui section） is a deep and large fault with multi-stage activity：in Caledonian period, faults began to develop; the faults controlled the differences of lithology, sedimentary facies and sedimentary environment on both sides of the fault from Cambrian to Late Devonian period, showing the characteristics of synsedimentary active faults. The Indosinian faults are mainly characterized by S-N thrusting and bedding shearing; the Early Yanshanian faults are mainly a series of SE-NW thrusting nappe structures and brittle faults; the Late Yanshanian faults are characterized by normal faults and translation faults; and the Himalayan faults are characterized by normal fault activity.
