Type:
A set of mafic scoria cones and associated lava flows occur in the valley located between the towns of Cuatro Ciénegas and Ocampo in Coahuila. These structures form the Plio-Quaternary Ocampo volcanic field. The isotopic age of these volcanoes ranges between 1.82 ± 0.20 Ma and 3.41± 0.55 Ma.
The volcanic rocks are hypocristalline with a pilotaxitic or intergranular texture in the matrix. Olivine + clinopyroxene + plagioclase + titanomagnetite occurs as phenocrysts in the rocks.
The coordinates represent the approximate baoundary of the field.
