Quaternary evolution of the El Tromen volcanic system, Argentina, based on new K-Ar and geochemical data: Insights for temporal evolution of magmatic processes between arc and back-arc settings

The new data coupled with those previously published highlight that, in the last 2 Ma, the Tromen Volcanic System (TVS) erupted transitional, alkali and rhyolitic lavas which built the Tilhué, Chapúa-Maipo-El Puente, Coyocho-Wayle and El Tromen volcanic groups. Four partial melting events have been...
