TERTIARY FORMATIONS OF OLTENIA

be deposited at the end of the Middle Eocene and continued until 

 the Oligocene. In this horizon there occurs the fossil resin of Olanesti 

 (malul Purdoi) and Cheia. 1 



3. Upper. — We find in the southern region of Muereasca another 

 zone of sand and shingle and limestone blocks with, at rare intervals, 

 bands of conglomerates and sandstones. At Muereasca de jos I 

 have found Nummulites and Orbitoides, which are indications of 

 Oligocene, but characteristic of no particular horizon; probably we 

 have here beds also of the Lower Oligocene. All these formations have 

 in the Olt valley a direction southeast by east to northeast by east,

and dip south-southeast at a quite variable angle of about 40 . In 

 the west of Cheia we find them running from east to west, and in the 

 east of Dangesti also K. Redlich and Sabba Stefanescu report an 

 east-to-west direction for these beds. Obviously the Paleogenic 

 Flysch must make an interesting horizontal inflection in the Olt 

 region. Insignificant undulations, but not folds, are also to be seen 

 here and there (at Olanesti below the spas, etc.). 



We meet, further, with the Paleogenic formations in close rela- 

 tion with the mountains only in the high plateau of Mehedinti, where 

 they form a narrow zone westward from Baia de Arama up to Batta. 



B. THE PALEOGENIC KLIPPES OF SACEL AND SLATIOARA 



When we leave the Olt region, we find the Eocene appearing as a 

 small but interesting klippe in the Blahnita valley at Sacel (Gorj.). 

 It includes conglomerates, grits, and sandstones identical with those 

 from Calimanesti (Valcea), inclined at an angle of 5o°-6o° toward 

 the south-southeast, and constituting the bottom and walls of the 

 valley, about 6oo m (Fig. 2). This cliff has been the subject of much 

 discussion between Gr. and Sabba Stefanescu.
