TERTIARY FORMATIONS OF OLTENIA 683 



These fossils show us that the lower horizon of the salt formation, 

 with its sandy conglomerate facies, is the continuation of the strata 

 of Gura Vai, and accordingly is to be classified under the / Medi- 

 terranean Sea deposits. To the west of Govora Spa, at Folesti- 

 Tomsani and Maldaresti, the layer with the banded facies is very 

 thick, and though fossils are not found, it is not impossible that the 

 lowest beds should belong to the Oligocene; the same arrangement 

 is to be observed at Barbatesti, where the beds seem to be a continua- 

 tion of the Oligocene strata like those from Gura Vai (Olt). In the 

 Slanic and Trotusu Basins, and also in the north Carpathians (Gali- 

 cia, etc.), this horizon of the Subcarpathian Miocene salt formation 

 occurs, according to the description of Mrazec and Teisseyre, 1 

 Zuber, 2 etc., similarly to the Oltenian one. 



The salt formations 0} the Olt region, and indeed the whole Sub- 

 Carpathian salt formation, have accordingly come down in the world 

 as far as and including the Burdigalian. 



The occurrence of eroded Nummulites near Ocnele Mari- Govora 

 is evidence that in / Mediterranean times a redeposition of Paleo- 

 genic material took place; this view is supported also by the topo- 

 graphical and stratigraphical relations of the two formations in 

 contact. The conclusion from these facts is, as proved for other 

 localities in the Carpathians, that at the end of the Oligocene, and 

 beginning of the Burdigalian age there was an important dislocation 

 in this region, more pronounced in the west at the contact ivith the 

 skirt of the Carpathians. 



a) Petroleum and salt. — This formation is important, because in it 

 we find: petroleum at Gavora Spa, and Ferbea; natural gas at 

 Ocnele Mari, Teiusu, Gatejesti, 3 Pausesti, Barlog, Valeni, etc.; 

 mineral wells, containing iodine, etc., at Gavora, Bunesti, etc.; and 

 salt wells at Olteni, Govora Spa, Pausesti (de Otasau), Slatiora, 

 etc. ; and many localities with salt efflorescences. The petroleum
