Beishan Orogen is a key area of Tianshan-Xing’an Mongolian Orogen. The geological-geochemical study on the ophiolite units from the region will be of great significance for the evolution research of the Central Asian orogenic belt. This research focuses on major elements, trace elements, Sr-Nd-Pb-Hf isotopic compositions and SHRIMP geochronology of the Yueyashan ophiolite suites in Beishan. With respect to the regional geological features, this paper suggests that the Yueyashan ophoplites formed in a tectonic setting of intraplate discordogenic fault-the original rift evolving to a limited small oceanic basin.
