A suite of Cenozoic shoshonitic basalts bearing abundant mantle-derived xenoliths and xenocrysts outcropped in Maguan area, Yunnan Province. This study provides results of petrological and geochemical characteristics of the Cenozoic shoshonitic volcanic rocks, aiming to offer some food to thoughts related to volcanism and mantle-crust interation induced by to the continental collision between India and Asia plates. The results showed that Cenozoic shoshonitic basalts from this area have relatively high and variable alkali contents, and are rich in potassium. The Cenozoic shoshonitic basalts formed in a within-plate tectonic setting, the petrogenesis of which is related to the lateral extrusion of asthenospheric mantle along the southeastern of Tibetan plateau induced by the Indo-Asia collision.
