China in the Silurian period

During the Silurian Period, tectonism was fairly marked in the Chinese region, and extensive shallow‐water marine transgressions occurred, with the accompanying development of eugeosynclinal and miogeosynclinal regimes. In the Late Silurian, a Caledonian (Kwangsian) orogenic movement affected several regions of China and regression was marked.

The Lower Silurian of China is principally a graptolitic facies, with 12 zones, giving place in the Middle Silurian to a predominantly shelly facies. The Upper Silurian is similar to the Middle Silurian but is usually more clastic and less fossiliferous, especially in the higher parts.
