| Abstract: | The section was measured from the Erlangba,Ningqiang county,Shaanxi Province. About 160 genera and species, including conodonts, graptolites, brachi-opods, trilobites, and all kinds of coral fossils, were well distinguished.According to the properties of the rocks, lithotacies and the characteristics of the fossils, the writers devided the sections into Longmaxi Formation, Ghuijiagou Formation, wangjiawan Formation and Ningqiang Formation.In the past, the Nin-gqiang Formation was generally regarded as M-L Silurian or M.Silurian or E-M silurian on the basis of the fossils of the benthonic organism. In this paper the Ningqiang formation is referred to as the P.Colloni assemblage.The zone and the age should be the earliest Silurian in terms of the characteristics of the conodont faults. |
