Ca, Sr and Ba contents of 186 volcanic rocks (andesites, dacites, rhyolites, basalts, basanites and shoshonites) collected from the central Andes volcanic zone, southern Peru, have been determined by a inductively coupled plasma emission spectrometry. A SB systematics is drawn on a Sr/Ca-Ba/Ca diagr...
