Way Group (Spanish: Grupo Way) is a geologic group of Lower Cretaceous age located in northern Chile. The sediments of the group deposited in Coloso Basin, a small intra-arc basin made up by a half graben. The now inactive Coloso Basin is elongated along a NNW-SSE oriented axis and has its southwestern border made up by faults.
The Way Group is made up of the following arrangement from top to bottom the Tablado Formation made up chiefly of limestone, the conglomerate-gravel-sandstone Lombriz Formation and the conglomerate and breccia dominated Caleta Coloso Formation.
