Cerro Chascon is located within the moat of the Pastos Grandes caldera (q.v.)

Cerro Chascon is a torta with its vent located roughly in the geometric centre of the body, and it is part of a remarkable chain of small silicic lava bodies (Cerro Runtu Jarita) extruded from a fissure, which probably form the surface expression of a subsurface dyke similar to that described connecting the Inyo domes, California (Fink and Pollard, 1985). Evidence of initial explosive activity is preserved in a small local rhyolitic airfall.
