| 摘 要： | 洋岛地层序列在造山带地区往往十分发育,它们在时间上、空间上具两大特点,时间上往往失序,空间上移位。东昆仑万保沟岩群也有洋岛地层序列通常具有洋岛型火山岩基底和碳酸盐岩盖层的双层式结构,具有低分异度、高丰度和地方性色彩的生物群面貌,因而温泉沟岩组和青办食宿站岩组在时间上具先后、空间上具紧密的关系。

| Abstract: | Stratigraphic sequences of oceanic islands are typically well-developed in orogenic belts. They are usually characterized by temporal anachronism and spatial displacement. This paper presents a case study of the Wanbaogou Group in the eastern Kunlun Orogenic Belt. The Wanbaogou Group consists of two sets of strata: a basement with oceanic island volcanic rocks capped by a succession of carbonate deposits, which contains faunas of low diversity, high abundance, and high endemism. |
