The upper deposits of the Flysch no longer show the same facies 

 as in the east. While the lower strata still show some similarity of 

 fauna, neither the green conglomerates (a local facies in the east) 

 nor the characteristic menilitic schists, or the Kliwa sandstone is seen. 

 I have shown elsewhere 1 that the upper deposits of Muereasca- 

 Olanesti correspond to the Targu-Ocna strata; another point of 

 similarity would exist if my suggestion, that the Eocene layers of 

 Oltenia should have salt and petroleum, should hold. 



As for the Miocene salt formation of Oltenia, its similarity with the 

 east and west salt formations, and more especially with the Slanic 

 and Trotus Basins, may be clearly seen from the above. I have 

 shown that the Oltenian salt formations consist of two horizons: 



a) Conglomerates, shingles, and sand, with less important colored 

 marls, gypsum, and palla, belonging to the / Mediterranean Sea 

 (Burdigalian and perhaps Helvetian in parts). Its constitution 

 shows a coast and lagoon facies, and its relation to the Oligocene 

 layers — in some localities conformable, but in others unconformable — 

 and more particularly the occurrence of water- worn Nummulites, etc., 

 are evidence for the regression of the Flysch Sea, and the beginning 

 of the Mediterranean Sea, at the end of the Oligocene, with other shores. 



The reddish facies of this horizon, with its gypsum and marls, 

 represents a deposition at some distance from land; both facies 

 correspond, as regards position and stratigraphy, with the similar 

 formations of the Slanic Basin. 



b) The upper horizon, gray-bluish marls with Globigerinae, lies 

 above the Burdigalian in the Oltu valley, and, like the deposits of 

 the Slanicu and Trotus Basins, is a deposition far from the Flysch 

 shore. The palla characteristic for the Subcarpathian Miocene salt 

 formation is represented, perhaps even more abundantly, to the 

 west of the Olt River. It appears with the banded facies of the 

 Burdigalian, and continues up to the upper Tortonian, like that of 

 Transylvania. There are two kinds of palla; a genuine tuff with 

 an eruptive crystalline facies predominant, and a levigated palla, like 

 Trass, with a sedimentary facies predominant, just as was observed 

 in the Slanic Basin. 



Gypsum is also represented in Oltenia, and comes in the upper
