Preliminary Issues on Nucleation Phenomena in Regional Gravity Axes

Abstract

Irrespective of their univocal or biunivocal structure, gravity axes facilitate the emergence of nucleation phenomena, the genesis of certain settlements with polarizing functions of various ranks and hierarchical levels. The formation of the habitational nuclei takes place in the areas where natural gravity reaches representative parameters, such as river confluences, depressions and the more spread out sectors of the river meadows, where a concentration of the vectors of the geomorphologic evolution is remarked. The nucleation processes follow a spiral of conditionings, being triggered by the natural facilities and subsequently amplified by the diversification and the intensification of the human activities.
