| Abstract: | Yutian group is composed of Shuitoujin formation and Changpu formation in south Jiangxi. Changpu formation is a rock assemblage of medium-basic volcanic rock which containes medium acidic volcanic rock interlayer. It is mainly distributed in Longnan basin, Changpu basin, Baimianshi basin and heling Basin. The paper mainly discusses on the petrology and petrochemistry charactaistics of volcanic complex of Yutian group,and the possible tectonic environment of volcanic complex formation and its genesis mechanism. |
