| 摘 要： | 西藏羌北地区从未发现过有可靠化石依据的石炭纪地层。在西藏1∶25万玛依岗日幅区域地质调查中,于原侏罗系分布区内,发现了一套厚度大于298·05m的以碳酸盐岩为主夹碎屑岩地层。碳酸盐岩中含丰富的Eostaffella、Pseudoendothyra、Milleralla、Ozawainella、Pseudostaffella、Profusulinella、Fusulina、Fusulinella、Triticites、Protricites等,属于典型的石炭纪分子。虽未见顶、底,但它是羌北地层分区的唯一一处有可靠化石依据的石炭纪地层,故建立瓦垄山组(C1-2w)。 |

| Abstract: | There have been no previous of Carboniferous strata in northern Qiangtang, Tibet based on reliable fossils. During our 1∶250 000 geological survey, a section of carbonate and clastic strata with a thickness of 298.05 m was discovered in an area of widespread Jurassic strata. Abundant late Carboniferous fusulinids are found in this section including Eostaffella,Pseudoendothyra,Milleralla,Ozawainella,Pseudostaffella,Profusulinella,Fusulina,Fusulinella,Triticites,and Protricites. The base of the section is not exposed .We have designated this Carboniferous section as the Walongshan formation(C_ 1-2 w) . |
