BackgroundA mostly Pliocene volcanic field is located near the town of Los Volcanes, at the southern end of the Atenguillo graben in the Jalisco tectonic block of western México. The 285 km2 field consists of lava cones and flat-topped flows overlying Cretaceous ignimbrites. The youngest products are earliest Pleistocene in age (Potassium-Argon date of 1.56 Ma). The extensional tectonic setting, in a graben of the Jalisco block, has resulted in the eruption of a wide variety of lava types, ranging from potassic minettes and leucitites to calc-alkaline basalts and andesites.
