Geological Formation of The Area
Actual Polesine territory is, geologically speaking, of recent formation, created by drifts taken by rivers Po and Adige, and subsequently from human modifications. In fact, men reclaimed and decontaminated the area before embanking the biggest waterways.
First origins goes up to the Pliocene epoch. Contemporary to the rising of Alps and Apennine Mountains, the entire Padania was filled by a long inlet (the Adriatic depression) and the seabed of this huge ditch was full of troughs and elevations.
At the end of the last glaciation (10.000 years ago), most of Padania actual territory was just formed. Landscape's last mutation was dued to the raising of the sea level and the ice melting.
In 1604, river Po's natural course was artificially modified and after this work actual delta was formed. Floods frequently happened in Polesine filled the depressions of the area with several bundles of sediments consisting in sand, clay and silt.

Famous quotes containing the words geological, formation and/or area:
“The crystal sphere of thought is as concentrical as the geological structure of the globe. As our soils and rocks lie in strata, concentric strata, so do all men’s thinkings run laterally, never vertically.”
—Ralph Waldo Emerson (1803–1882)
“It is because the body is a machine that education is possible. Education is the formation of habits, a superinducing of an artificial organisation upon the natural organisation of the body.”
—Thomas Henry Huxley (1825–1895)
“Prestige is the shadow of money and power. Where these are, there it is. Like the national market for soap or automobiles and the enlarged arena of federal power, the national cash-in area for prestige has grown, slowly being consolidated into a truly national system.”
—C. Wright Mills (1916–1962)
