and natural gas occur here along an anticline dislocated by a fault 

 which extends from Govora Spa to Otasani. 



That fault explains why at Govora Spa we have two wells, at a 

 distance of a few meters only, with totally different mineral waters; 

 one well is bored in the lower salt formation, the other in the higher. 



b) The Slatioara anticline. — We have stated that the shingle and 

 sand with conglomerates was considered by Gr. Stefanescu to be 

 Eocene, but from the tectonic and the facies it seems to me that the 

 western part, at least, at Maguricea in the Cerna valley must be Oligo- 

 cene. (Fig. 3.) The adjoining Sections (Figs. 5 and 6) summarize the

stratigraphical and tectonical facts. At Maguricea, in the Moarea 

 valley (Fig. 3), the lower banded facies of the conglomerates of the 

 salt formation rests unconformably on the Oligocene shingle. While 

 some sulphur springs with hydrocarbons originate in the Oligocene 

 shingle beds, other ones, as well as the salt springs, come from the 

 salt formations, which in the higher horizon contain an intercalation 

 of palla. The continuation of palla on the north side of Maguricea 

 and Coada Magurei indicates an old anticline. While at Maguricea 

 the banded salt formation rests undisturbed above the Oligocene beds, 

 in the east we find the whole salt formation folded and thrust south- 

 ward, and a very obvious overlapping of the Pontic strata above the 

 salt formation. This is well seen at Coada Magurei and eastward 

 (Figs. 5 and 6) : there, over the folded marls with intercalations of 

 palla covered by Sarmatian strata, come the Mceotic (or Pontic ?)
