boninite, Caribbean island arc, Island arc tholeiite, felsic rocks, Sm-Nd isotopesAbstract
Located in the NW Cordillera Central, the Lower Cretaceous Amina Fm comprises a sequence of volcanic protoliths variably deformed and metamorphosed. The deformation was heterogeneous and consisted in N- to NW-directed regional ductile oblique shearing, which produces a penetrative plano-linear Sp-Lp fabric of mylonitic characteristics and a macrostructure consistent in thrust-nappe stack inclined to the SW. The sin-Sp metamorphism was in the low-T greenschist and locally prenhite-pumpellyte facies conditions. Combined detailed mapping, geochemistry and Sr-Nd isotopic studies have shown that the Amina Fm include four mafic protoliths and an additional felsic one: island arc tholeiites, Ti and LREE-depleted island arc tholeiites, boninites, calc-alkaline basalts and low-K rhyolites. The source for these rocks was a variably depleted mantle, overprinted by a subduction zone component. There are strong geochemical, isotopic and petrogenetic similarities between the Amina and Maimón Fm protoliths and the Los Ranchos Fm volcanic rocks, which imply that the first group of rocks is the tectonometamorphic equivalent of the second. All of these rocks have the typical characteristics of intra-oceanic island-arc igneous suites and so, all together they represent the formation and development of the primitive Caribbean island arc in Hispaniola during the Aptian-Albian. The regional geochemical maps and transverses of selected trace elements for the three formations ensemble suggests a location for the related subduction zone, to the W, NW and N of the current position of the Amina-Maimón domain.
