Clastic-supported polymictic conglomerate with a greenish-brown color. It has a poor selection (sizes from 2 mm to 4 cm) and the shapes of the clasts are mainly subangular, so the textural maturity is low. It is composed by lithoclasts of sedimentary and igneous rocks (volcanic and plutonic), in addition with grains of Quartz and Feldespars. It has a clay matrix and carbonate cement (reaction to HCl).
