A co-ignimbrite ash is a cloud of fine ash particles that overrides a pyroclastic density current. The process responsible for the formation of these clouds is called elutriation. The co-ignimbrite deposit overlies the Tara ignimbrite and is capped with dilute flow, surge, and possibly flow deposits. This is the only co-ignimbrite ash deposit ever identified in the central Andes.
