TERTIARY FORMATIONS OF OLTENIA

the Vasilatu valley (west of Brezoi), which has here and there traces 

 of undeterminable fossils, but where Inoceramus can be distinguished. 

 2. On the other hand, I do not think that the whole deposits from 

 the Brezoi Basin are Senonian, but that the upper strata belong to 

 the Eocene, corresponding to the Eocene strata from the opposite 

 Titesti Basin. Dr. Redlich tells us that in the strata with Orbitoides 

 (upon the sandstones and marls with Inoceramus), he has found a 

 section similar to one of Nummulites; still more important evidence 

 is revealed to us by the stratigraphy and facies of the deposits (Figs. 

 1 and 4). 



Fig. 1. — Profile of the Lotru valley at Brezoi; 1 : 100,000. 

 H = Mica schist with £ = pegmatite veins; B = Brezoi breccia; cr = Upper Cretaceous; g = sandstone 

 and grit; m = marls and sandstone with Inoceramus Cripsii; eo = coarse conglomerates with Hippurztes 

 limestone blocks; i ? =fault. 



Omitting the consideration of the Brezoi breccia, we find that the 

 coarse conglomerates, shingle, and sandstones with an intercalation, 

 in the lower horizon, of a thick bank of marls and fine silicious sand- 

 stones, bend themselves into small undulations, with an anticline 

 more pronounced on the side of the Calimanesti valley. Between 

 Brezoi and Valea lui Stan I can confirm a small syncline with many 

 folds in the marls. The whole formation is inclined toward the 

 southeast (angle variable from 3o°-6o°), and it lies in obvious uncon- 

 formability on the mica-schists and Brezoi breccia, which form 

 klippes at the bottom of these deposits. A fault along the right bank 

 of the Lotru has been confirmed by Dr. Redlich and myself at the 

 same time. 1 



The marls, contrary to the interpretation of K. Redlich, consti- 

 tute a horizon intermediate between the conglomerates and sandstones 

 from the Vasilatu valley, which are rich in Senonian fossils, and the 

 coarse conglomerates in the east of Brezoi, rich in huge blocks of 

 limestone, with Senonian fauna.
