| Abstract: | The basal dolomite of Huangloug Formation is widely distributed in S. Anhui region. About its geochronological assignment, there are different opinions.Abundant fusulinids and conodonts were collected from the basal dolomite of Huanglong Formation in this region, they are Pseudostaf fella antiqua, Ps.ex gr. composita, Ps. kanumai pauciseptata, Ps.kanumai PS. sphaeroidea, PS. cf. larionvae, Profusuimella of cybaea,Pr.cf wangyui,Ps.toriyamai,Pr.parva, Verella prolixa, Schubertella sp. ,Eostaffella of. rotunda,E. of angularis, E.of. ljudmidae,Declin-oguathodus noduliferus, D.corrugutus, Euprioniodina microdentata, E.caverna, Hibbardella parva, Hindeodella hibbardi, H.subtilis, H.ibergensis,Diplogna-thodus edentatus,D. nodosus, Idiognathodus delicatus, Neognathodus symmetricus, Ozarkodina delicatus, O.hindei, prioniodina sp., Spathognathous sp., Adetogna-thodus lautus, Based on this fossil assemblage, the age of this dolomite should be Early Middle carboniferous. |
