摘要:
详细描述了西藏自治区改则县拉清乡汤模长二叠系剖面,自下而上划分为拉嘎组、昂杰组和下拉组.讨论了二叠系昂杰组和下拉组的岩性组合特征和沉积环境,其中昂杰组横向延伸不稳定向西相变尖灭.依据化石分布及组合特征,建立了Neoschwagerina-Chusenella conicocylindrica蜓组合带、Pachyphloia ovata-Eotuberitina reitlingerae非蜓有孔虫组合带、Lytvolasma asymetricum-Bradyphyllum caninoidia珊瑚组合带和Akagophyllum coqenense-Amplexocarinia muralis珊瑚组合带.昂杰组为早二叠世,下拉组下部为中二叠世栖霞期,而下拉组上部为中二叠世茅口期,并以暖水型气候环境为主.在昂杰组—下拉组中发现了珊瑚的2个新种和1个新亚种,并进行了描述.新种名称分别为Lophotabularia longiseptata sp.nov.和Iranophyllum longiseptatum sp. nov.,新亚种名称为Cyathocarinia tuberculata multiseptata sub sp.nov.。
