BackgroundThe Ventura volcanic field consists of a group of maars and pyroclastic cones located immediately NE of the city of San Luis Potosí in the southern Basin and Range province of central México. The largest and best-known maar is La Joya Honda, a 850 x 1100 m wide, 300-m-deep maar erupted through Cretaceous limestones about 1.1 million years ago. The maars, located near the southern end of the Basin and Range province, are known for their mantle-derived spinel-lherzolite xenoliths and deep-crustal granulite xenoliths. A 10-km-long lava flow also rich in lherzolite xenoliths was erupted from the Cerro Verde cinder cone north of La Joya Honda.
