- W1984334933 abstract "Potassium-argon measurements were made on 17 samples from the ultimate stage of activity of the Piton des Neiges volcano, which corresponds to a differentiated series with lavas varying from basalt to quartz trachyte. Samples were selected as a function of their stratigraphic position and their representativity of magmatic evolution. The technology used to date young volcanic rocks (Pleistocene) by KAr is described and discussed because of its reliability in the analysis of modern lavas and because of the agreement of the results with the available stratigraphic control. The data, together with those previously obtained by McDougall, yield ages ranging between 330,000 and 30,000 years, with two mainly effusive periods separated by a phase of instability of chiefly explosive volcanism around 190,000 to 150,000 years ago. A rough correlation between the chemical evolution of the lavas and time is established. The Kudo and Weil geothermometer, when cross-checked with Buddington and Lindsley's geothermometer, allows us to establish that the lavas of the two effusive periods correspond to two different depths of the magmatic chamber in the oceanic crust (17 and 10 km respectively). The phase of instability may correspond to a sudden variation in these magmatic conditions. The differentiated series, the ultimate stage of activity of the Piton des Neiges volcano (330,000 and 30,000 years), can be explained as the evolution of a magmatic body, isolated when the focus of basaltic eruption migrated southeast from Piton des Neiges to Piton de la Fournaise." @default.
