Magma genesis in the Lesser Antilles Arc: Evidence from Sr-Nd-Pb-Hf isotopes of Saba volcanics

Saba is a volcanic island and is part of the Lesser Antilles island arc, which is related to the ongoing subduction of the Atlantic oceanic plate underneath the Caribbean plate. This arc has been studied extensively because of the recent volcanism. Also, there is a north to south gradient in chemical and isotopic composition of the lavas. This...
