The Velodrome is a large recumbent fold spilled southward, formed at the end of the Tertiary (23 to 5 million years) at the Alpine front. It consists of sedimentary series (also known as molasses) composed mainly of sand, sandstone and conglomerate (rock composed of pebbles welded by a rocky cement thinner) produced by erosion of the Alps. Molasses accumulated at the foot of the reliefs in the Alpine sedimentary basin Valensole, along which the fold of the Velodrome was formed. The term evokes the Velodrome, used by geologists from the 50s, means the marine basin filled and distorted.
