Chenaillet Lava Pillow

Title: Chenaillet Lava Pillow
Description: At the Colletto Verde, on the border between Italy and France in the Montgenevre sector, there is an outcrop of basaltic lavas, rare evidence of an ocean floor 160 million years old. The western side of the outcrop, a 80 meters high wall, is divided into subspherical sized structures between 0.5 and 1 meter or more ellipsoidal shapes stretched and flattened. The scientific term "pillow lavas" derives from their characteristic shape similar to large pillows or bubbles. The choice of this geosite is motivated by the relevance petrographic-mineralogical importance that these structures are found in the Alpine arc.; another interest are the petrographic elements
