Abstract
In the north-eastern part of Romania, along the Prut river valley, are known geological deposits with containing flint. Although there are many scientific books and studies about the geology of the region in which are presented aspects relating to flint and its occurrence in the area, they do not provide the information required for a correct interpretation in relation with the use of these important natural resources by the prehistoric communities. Based on researches, the present study highlights a large morphological variety of flint occurring on the Prut Valley, in terms of its color and physical properties. It is also pointed that flint presence in the area is both in relation with the primary geological deposit, where it was formed from Cretaceous time, and with the layers in which it was later reshuffled in respectively Badenian levels, in Quaternary-Pleistocene terraces and recent alluvial deposits.
