英文摘要	Is Qiangtang block in North Tibet an ancient continental block or fold belt? And how is its composition (tectonic framework)? These are the geological topics still in debate. Qiangtang is far from human society. It is one of the places in the world with lowest geological working degree. The lacking of basic geological data is an important reason, which makes the related geological problems difficult to get clear and correct interpretation. Chasang is located at the inner part of Qiangtang. The Upper Triasde Xiaochaka Formation there is composed of spillite, basalt, mediurn-basic volcanic rocks, basaltic breccia, intercalated with limestone and marble at the lower part, elastic rocks (flysch) and limestone at the upper part. Sandstone and siltstone samples were collected from the flysch of the upper part of Xiaochaka to do major element geochemical analysis for tectonic-setting discrimination. The result of this research indicates that the tectonic setting of Xiaochaka flysch is oceanic island are of an active continental margin, and its sedimentary provenance is mainly intermediate volcanic rocks.
