摘　　要：西藏羌北地区石炭纪■类动物群是笔者等于2004年首次发现的,并将动物群所在层位建立了瓦垄山组,该套地层中产大量的■类化石,种属多,分布连续。经研究,自下而上建立6个■类化石带:(1)Eosta ffella mosquensis带,(2)Millerella-Eostaf fella带,(3)Pseudostaf fella-Eostaf fella带,(4)Pro-fusuliena带,(5)Fusulina-Fusulinella带,(6)Protriticites-Triticites带。该套含竹蜓类化石地层的发现,为研究羌北地区晚古生代构造活动提供了信息,也为研究该区石炭纪地层、古生物、生物古地理、区域性地层划分和对比提供了依据。The Carboniferous fusulinids were discovered by the writer and others in 2004 when carrying on a geological investigation in Northern Qiangtang,Tibet. The Walongshan Formation was established then and it is featured by abundant fusulinid. Six fusulinid zones were established as follows： （1） Eosta f f ella rnosquensis zone, （2） Millerella - Eosta f f ella zone, （ 3 ） Pseudosta f f ella - Eosta f f ella zone, （4） Profusuliena zone, （5） Fusulina - Fusulinella zone, （6） Protriticites- Triticites zone. The sequence of strata, being rich in fusulinids, could provide some information to the Late Paleozoic tectonic pattern of the studied area and provide some basic materials for studying the Carboniferous strata, its paleontology, palaeogeography and for the classification of the strata.
