    • 摘要: 西藏北部中扎县永珠地区德日昂玛-下拉剖面中石炭系和二叠系地层发育完整,出露良好,化石丰富。该剖面中查果罗玛组碳酸盐岩地层(泥盆纪-早石炭世)和下拉组(中二叠世)碳酸盐岩地层之间的碎屑岩夹灰岩地层,在沉积上表现为冰海相杂砾岩,在古生物化石面貌上表现为特提斯-冈瓦纳古生物群混生。古生物群混生的现象为石炭纪-二叠纪的特提斯生物区与冈瓦纳生物区之间的地层和古生物对比建立了一座桥梁。永珠组中上部地层中同时产有牙形石和腕足类,牙形石的研究表明其时代为晚石炭世莫斯科期,而腕足类的研究则表明其为早二叠世萨克马尔期。这一矛盾预示着在(亲)冈瓦纳相地区晚石炭世晚期地层缺失的意见需要重新审视。
