浙江长兴二叠系-三叠系界线层型剖面面临的新问题THE PERMIAN-TRIASSIC BOUNDARY GSSP AT MEISHAN,CHANGXING,ZHEJIANG,FACES NEW PROBLEMS
王成源
摘要(Abstract)：
长兴煤山P/T界线在27层中间,H.parvus带之上应为I.staeschei带,不是I.isarcica带。H.parvus带厚仅4cm,可能包括H.parvus和I.lobata两个化石带的时间间隔;界线层不仅高度浓缩,而且有硬底构造,缺失一些牙形刺分子,很可能在界线层中有小的沉积间断。
关键词(KeyWords)： 二叠系-三叠系界线;界线层型剖面及点位;I.staeschei带;H.parvus带;间断;硬度构造;浓缩;煤山;浙江
