【 摘 要 】

The Ordovician deposition is characterized by a thick carbonate in the Tarim Basin. In northwestern section of the basin, rocks are chiefly deposited in a carbonate ramp. Twelve microfacies have been distinguished on the basis of their depositional textures and petrographic analysis. Four depositional belts such as tidal flat, lagoon, shoal and open marine can be identified.
