A group of lava domes and pyroclastic cones of Pleistocene age is located on the western side of Cerro Grande, a Miocene caldera north of La Malinche volcano. Pyroclastic-flow deposits within the caldera are those of the Xáltipan ignimbrite, which originated from Los Humeros caldera to the east about 0.45 Ma (million years ago). A Potassium-Argon age of 0.49 Ma was obtained for the lava domes at Cerro Grande. Post-caldera Pleistocene activity at Cerro Grande covered a broad area on the SW-NW side of the caldera, producing andesitic and dacitic lava domes and basaltic lava cones and pyroclastic cones.
