| Abstract: | The Early Ordovician rocks in East Yunnan are composed of elastic sediments: sandstones, shales, quartzites with iron manganese-rich intercalations and ripple-marks, cross-beddings. Trilobites Taihungshania, Neseuretus, graptolite Didymograptus deflexus,brachiopods Lingula and other inarticulate genera , trace fossil Cruzicna and acritarchs Striatotheca and Coryphidium are common. This suite of shallow water sediments is of Gres Armoricain factes Which is widespread in southwest Europe,North Africa, Middle East and East Newfoundland. The Gres Armoricain factes is considered to be inshore sediments at northern marginal areas of Early Ordovician Gondwana. |
