Abstract:

The Lower Carboniferous Bachu Formation and Karashayi Formation developed in Tahe Region could be divided into massive sandy conglomerate facies,platy cross-bedded conglomeratic sandstone facies,trough cross-bedded conglomeratic sandstone facies,platy cross-bedded sandstone facies and 4 depositional systems such as braided river delta system,delta system,lagoon-flat system and carbonate platform system.The braided river delta system developed well in the region,and plays the main part of the Carboniferous System;carbonate platform could only be found on the bottom of the Bachu Formation.

Key words: microfacies, depositional system, Carboniferous System, Tahe Region
