Abstract
Abstract: 87Sr/86Sr, major and trace element data are presented for calc-alkaline lavas from Santorini and Milos, Aegean Sea, Greece.87Sr/86Sr ratios of fresh lavas from Santorini range from 0.70472 to 0.70509 whereas those of fresh lavas from Milos lie in the range 0.70540–0.70620. Altered lavas from both islands have higher87Sr/86Sr ratios (up to 0.70573 and 0.70662 respectively). The range of87Sr/86Sr ratios of fresh lavas from Santorini is only just greater that the maximum analytical uncertainty and is thus considered to reflect that of the parental magmas from which the lava series was derived (by fractional crystallization at low pressures). For the analysed Milos lavas (dacite-rhyolite) there is no correlation between87Sr/86Sr and any major or trace element concentration and this, together with the fact that the87Sr/86Sr ratios are similar to those of basaltic andesites and andesites from Aegina and Methana in the northwestern part of the arc, likewise indicates that the87Sr/86Sr ratios are identical to those of the parental magmas from which the lava series was derived (also by fractional crystallization). The relatively high87Sr/86Sr ratios of the Santorini and Milos parental magmas indicate that terrigenous material has played a role in their genesis. This could be either via the subduction process or by assimilation of lower crustal material during ascent of mantle-derived magmas. The weight of the available evidence favours the latter possibility, but, even so, there are some indications that unusual mantle source material was involved in the genesis of the magmas.
