Durango volcan

Durango volcano is a volcanic field in north-central Mexico north of the city of Durango, located at the NW end of the Meseta Central and the eastern edge of the Sierra Madre Occidental. The volcanic field covers 2100 sq km and contains about 100 maars, cinder cones and lava flows.
Young activity occurred from the La Breña cone only a few thousand years ago.

Introduction:

The Durango volcanic field has erupted basanitic lavas and forms a large undissected lava plain within the Mexican Basin and Range province.
Many eruptions in the Durango field display an evolution from predonimantly maar-forming phreatomagmatic eruptions in the past to dominantly magmatic eruptions (strombolian activity) building cinder cones and erupting lava flows in younger times. This suggests a trend of decreasing presence of ground water in the area over time.
La Breña-El Jagüey maar complex consists of 2 intersecting maars, the largest of which (La Breña) contains a series of nested cinder cones. The maar complex is one of the youngest eruptive centers of the Durango volcanic field.
