stones and marls of Lower Jurassic age, and by Uijper Jurassic Lime- 

 stones ; by Cretaceous beds of Neocomian, Aptian, and Senonian age ; 

 by Xummulitic limestone and Miocene beds ; and by Quaternary 

 deposits; including the TschernoY-sjem. The most important volcanic 

 rocks of the Caucasus were erupted at the close of the Tertiary period, 

 but have produced only local effects in the upheaval of the chain.
