The lava dome of Cerro Chascon and the associated rhyolitic Cerro Runtu Jarita lava flow are located within the moat of Bolivia's Pliocene Pastos Grandes caldera. The roughly circular, flat-topped Cerro Chascon is located immediately NW of Laguna Khara. Cerro Runtu Jarita forms a roughly N-S-trending chain of small silicic lava bodies that probably represents the surficial expression of a subsurface dike. Minor eruptions of rhyolitic tephra preceded extrusion of the Cerro Runtu Jarita lavas. The age of Cerro Chascon was considered to by Holocene (de Silva and Francis, 1991), but new K-Ar dates give ages of 0.88-0.93 Ma (Watts et al., 1999).
