Several geological events have led to great complexity and diversity in the organization of our subsoils. Indeed, so-called plutonic rocks (gabbros) and metamorphic rocks (gneiss, orthogneiss, micaschites) characterize today our vineyard which extends from Gorges to Pallet via Monnières. In addition, there are different degrees of rock alteration (alterations, alteration clays) and erosion phenomena related to our topography.
