Abstract: | On the basis of the lithological and mineral composition of chalk, it is concluded that it was formed under various facial conditions. Carbonate sediment accumulated at a shallow depth and underwent wave movements. No correlation is found between the lithological chalk types and the facial conditions of precipitation of the carbonate sediment. |
