This paper gives a general view on the Stoliniceni Formation exposed mainly in the central area of Codru height. It reflects a short historical study of these deposits. It mentions the lithology and mineralogical differences of these deposits in comparison with the ones belonging to Balta Formation, with mention to the presence of jasper and other Carpathian originating rocks, whose presence it is for the first time mentioned on the Basarabia territory. The mineralogical structure is almost identical to the one from all terraces of Dniester and Prut rivers. As the initial type-section of Stolniceni Formation disappeared as consequence of rocks mining, we are proposing as lectostratotype the section located in vicinity of the village Leordoaia. About the geological age of these deposits there are several opinions. In our opinion, the fossil vertebrate fauna already studied probably belongs to the Late Turolian? (zone MN 13?)
