| Distribution and Ages of Ordovician and Silurian Marine Red Beds in Tibet |
| This paper deals with Ordovician and Silurian marine red beds in Tibet. Based on stratigraphic data obtained from field investigation of main sections in Tibet and other stratigraphic data of China, the authors recognized eleven Ordovician and Silurian marine red beds in Tibet. Among them six marine red beds are of Ordovician period and five marine red beds are of Silurian pereiod. Most of them belong to the shelf red beds, and only one of them is the oceanic red beds (marine reds bed of Ordovician Qingnidong Formation). According to the fossils contained in the marine red beds and the overlying and underlying layers, this paper preliminarily discusses the general ages of the red beds and makes an accurate correlation with the coeval marine red beds in the main regions of China. |
