The vineyards of our cooperative, Muscat de Lunel Vignerons, are cultivated on terraces full of alluvial deposits, that have been formed at the beginning of the Quaternary about 1,5 to 3 millions years ago.
During this era and before the formation of Rhone‘s delta, Durance and Rhone, both violent rivers, deposited on the plain a lot of pebbles brought from the Alps. Those grounds are now called terraces « fluviatiles villafranchiennes » (Alpin Diluvium).
Afterwards, horizontal strata at various depth levels have been composed of very fine elements’s deposit and of crushed pebbles brought by rain waters.
Today, it results from it a granular ground with gravel and pebbles that cover at the top of terraces the largest part of the soil. |
