Many mantle melts can be influenced by contamination from the crust and hence may display some chemical characteristics of volcanic-arc rocks without being associated temporally with the partial melting of a subducted slab; however, it is most likely that arc-type chemical signatures observed in volcanic and plutonic rocks in the study area arise from contamination of the asthenospheric source by previous subduction events.
5 Ma (Pardo et al, 2005) is also a possible consequence of the slab tear mechanism, with the nascent tear providing a path for ascending asthenospheric material.
