摘　　要：江西南部余田群包括水头迳组和菖蒲组。其中菖蒲组是一套以中基性火山岩为主夹中酸性火山岩的岩石组合，主要见于龙南盆地、菖蒲盆地、白面石盆地和河岭盆地。本文主要对余田群菖蒲组火山杂岩的岩石学特征、岩石化学特征和火山杂岩可能形成的构造环境、成因机制作了探讨。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.
