西藏北方羌塘地区石炭纪地层迄今尚无可靠的化石依据。在1∶ 25万地质调查中，在侏罗系分布区发现了一段厚298.05m的碳酸盐岩和碎屑岩地层。在该剖面中发现了丰富的晚石炭世类化石，包括Eostaffella、Pseudoendothyra、Milleralla、Ozawainella、Pseudostaffella、Profusulinella、Fusulina、Fusulinella、Triticites和Protricites。该剖面底部未出露，我们将该石炭系剖面命名为瓦龙山组（C_ 1-2 w）。
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) .
