In the development of the hydrographical network from the south of the Iezer Mountains between Valea Mare-Pravăţ and Stoeneşti-Cetăţeni one can distinguish three periods: inferior-Miocene, in which there is visible a wide valley with psefit-peltic accumulations in the surrounding sea basin; medium Miocene – Pliocene with clearly-cut valleys in the mountains, with the presence of some debris from a field close by to the mountains, on which valley chutes have transversely extended; intermittent tectonic movements have been detected in this period, which have triggered both slight elevations and mild dips that have led during the Pliocene towards a sedimentary environment. In the Romanian upper-Pliocene in which the mountain elevations are finally settled down, there are breaks into the non-proclivity crests from the sub-Carpathians, which determine an asymmetrical proclivity-inclined couloir towards the mountain. New generations of torrential valleys come up, which are transversely oriented on the previous ones (springing from the mountains
Abstract: The paper presents some thoughts that came to our mind when reading the presentation of Professor Tufescu from 1942, which defined him not only as a geographer, but as an exquisite realistic analyst. His intervention stands out as a pragmatic synthesis of Romania’s social and economic situation, during the second world war. The Professor envisaged realistic directions for the evolution of the continent’s peoples and not only. We aim at presenting only some of these ideas, demonstrated for some economic functions, which proved to be quite accurate in the following years.
