| Abstract: | WT10.5,10.BZ]The paper analyses the classification actuality and existing questions of the Yutian group of Mesozoic volcanic rock series in Longnan basin, Jiangxi province. According to lithology and lithofacies, the sandstone and conglomerate association of the low part of Yutian group should be classified into Shuitoujing formation, and the basic rock association of the middle part and the medium acidic rock association of the upper part of Yutian group should be classified into Changpu formation. The metamorphic rock association which is classified into volcanic rock series by former should be classified into Sinian cambrian system. The isotope data shows that geological period of Changpu formation in Yutian group is from middle Jurassic epoch to early stage of late Jurassic epoch. It needs further certification that the early Jurassic epoch sediment occurs in Shuitoujing formation or not. |
