Martinique Island has recorded the most complete history of the Lesser Antilles arc, from 25 Ma to present. The chemical and isotopic heterogeneity of the lavas is very large compared to other islands from the same arc and compared to other intra-oceanic arcs. The aim of this study is to explain the chemical and isotopic variability of Martinique lavas and to constrain the processes that took place during the genesis of volcanic products. We did a detailed geochemical study (major elements, minor elements and Pb, Sr, Nd and Hf isotopic ratios) of samples collected all over Martinique Island. Our geochemical study was coupled to precise dating of the same lavas by the K-Ar method through a collaboration with Aurélie Germa and Xavier Quidelle...
