Geochemical evidence for island-arc origin of the Villa de Cura Blueschist Belt, Venezuela

New geochemical data from the Villa de Cura indicate that it is a subducted (and exhumed) island-arc terrane. The majority of the basalts are primitive island-arc tholeiites (44.8--51.5 wt% SiO2, 6.7--22.8 wt% MgO). REE and immobile trace element data from the Villa de Cura exhibit island-arc signat...
