}}Cerro de los Chenques is a monogenetic volcano in the Chubut Province,^[1] Argentina, which is considered to be of Holocene age.{{sfn|Rivalenti|Mazzucchelli|Zanetti|Vannucci|2007|p=47}} The volcano developed on a basement formed by Mesoproterozoic and Neoproterozoic rocks and more recent volcanic and granitic formations.

The volcano is source of lava flows and pyroclastics. Cerro de los Chenques has erupted rocks ranging from alkali basalt to basanite, which contain phenocrysts ranging from clinopyroxene, olivine and plagioclase.{{sfn|Rivalenti|Mazzucchelli|Zanetti|Vannucci|2007|p=47}}

It is considered part of the Patagonian basaltic volcanics, which take place behind the main volcanic arc{{sfn|Rivalenti|Mazzucchelli|Zanetti|Vannucci|2007|p=47}} and are considered to be backarc volcanism. Such volcanics take the form of large volcanic plateaus.^[1] These volcanic are noted for their xenoliths which have been used to infer the composition of the mantle.{{sfn|Rivalenti|Mazzucchelli|Zanetti|Vannucci|2007|p=45}}
