摘要/Abstract

摘要： 西藏羌北地区石炭纪蜓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蜓类化石，种属多，分布连续。经研究，自下而上建立6个蜓类化石带:(1)Eostaffella mosquensis带，(2)Millerella－Eostaffella带，(3)Pseudostaffella－Eostaffella带，(4)Profusuliena带，(5)Fusulina－Fusulinella带，(6)Protriticites－Triticites带。该套含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。

关键词: 蜓类动物群, 石炭系, 羌北地区, 瓦垄山组

Abstract: 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)Eostaffella mosquensis zone,(2)Millerella-Eostaffella zone,(3)Pseudostaffella-Eostaffella 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.

Key words: fusulinids fauna, Carboniferous, Northern Qiangtang, Walongshan Formation
