The SAO is located within the eastern segment of the Jiangnan Orogen, extending ~40 km in the northeast direction. It is tectonically emplaced within the flysch formations of the Neoproterozoic Niuwu Formation of the Xikou Group. Available studies have indicated that the SAO formed at ca. 0.83 Ga, comprises structural peridotites, mafic cumulate rocks, pillow lavas, and sedimentary cover layers, and exhibits a typical tripartite ophiolitic structure. From bottom to top, this structure consists of (a) an ultramafic unit, primarily composed of serpentinized dunite with podiform chromitites, along with minor pure olivine rock, harzburgite, lherzolite, and pyroxenite; (b) a mafic unit, consisting of gabbro, gabbronorite, and diorite; (c) a volcanic unit, characterized by pillow lavas; and (d) a sedimentary cover, comprising siliceous rocks and overlying sedimentary cover layers.
