Nature
The Durango volcanic field is a broad volcanic region in north-central Mexico covering about 2,100 square kilometres east of the Sierra Madre Occidental. About a hundred cones rise from a high lava plain mantled by extensive flows, reflecting volcanism tied to tectonic extension and guided by northwest-trending faults, including the San Luis-Tepehuanes fault system. Its best-known features are the La Breña-El Jagüey maars, intersecting explosion craters ringed by tuff, with Jagüey now holding a permanent lake. The field erupted basanite containing mantle xenoliths, making it important for studying magma sources, and some eruptions may be geologically recent, possibly Holocene.
