Two small maars are located in the central Altiplano of Bolivia, north of Salar de Uyuni and east of Salar de Coipasa. Laguna Jayu Khota, at one time considered to be a meteorite impact crater, was formed by basaltic-trachyandesite explosive volcanism. Nekhe Khota maar lies 4 km SW of Jayu Khota; both were considered by de Silva and Francis (1991) to be of probable Holocene age, but no eruption dates are known. Phreatomagmatic eruptions produced basaltic-trachyandesite pyroclastic deposits containing granitic xenoliths. The maars lie along a transverse lineament; the alkali basaltic cone of Chiar Kkollu is located nearby where this lineament intersects the regional trend.
