摘    要:在西藏班戈县保吉乡嘎热扎地发现了一套碎屑岩和灰岩互层的地层,产珊瑚和苔藓虫化石。珊瑚化石共计7属3种及4未定种,分别为Procyclolites zizaensis Deng&Zhang,Chondrocoenia?sp.,Parastraeomorpha?sp.,Pamiroseris?sp.,Astraeomorpha multisepta Melnikova,Volzeia sublaevis(Laube&Volz),Radiophyllia?sp.,时代为中-晚三叠世。该套地层的发现表明,措勤盆地存在中-晚三叠世地层,为该地区的古地理研究提供了地层古生物学证据。

关 键 词:西藏  措勤盆地  嘎热扎地  中-晚三叠统  珊瑚

Abstract:A set of strata with interbedded clastic rocks and limestone,producing coral and bryozoa fossils,has been discovered in the Garezadi area of Baoji Township,Bango County,Tibet.Coral fossils belong to 7 genera,3 species and 4 undetermined species,respectively Procyclolites zizaensis Deng&Zhang,Chondrocoenia?sp.,Parastraeomorpha?sp.,Pamiroseris?sp.,Astraeomorpha multisepta Melnikova,Volzeia sublaevis(Laube&Volz),Radiophyllia?sp.,The times are middle-late Triassic.The discovery of this strata shows that the Cuoqin Basin has a middle-late Triassic stratum,which provides stratigraphic paleontological evidence for the paleogeographic study in this area.
Keywords:Tibet  Cuoqin Basin  Garezhadi  middle-late Triassic  coral
