| Summary: | and a southern source is the Cordillera Central. characteristics suggest that middle to late Miocene clastic chlorite/illite ratio and varied feldspar abundance. Type 2 Cibao basin in northern Hispaniola has been assessed via compositions determined by electron microprobe analysis eastern Cibao basin display two geochemically distinctive elements and rare earth elements (REE). Framework modes of feldspar grains, and the distribution and abundance of trace indicate derivation from plutonic, metamorphic, and possibly integrated methods including detrital framework modes, clay lower percentage of feldspar. These geochemical mainly from recycled orogen provenance. Individual feldspar margins setting. Multiple sources are suggested by this middle to late Miocene clastic samples suggest a source mineral assemblages and ratios, the composition of individual REE, Th, Sc and Cr+Ni values, correspond to relatively higher sediments in Cibao basin are related to an active continental sediments, with relatively higher total REE, Th, Sc and Cr+Ni study. A northern source is the Cordillera Septentrional, that the middle and late Miocene sediments in the central to The provenance of middle to late Miocene clastic sediments of type features. Type 1 sediments, with relatively lower total values, are consistent with lower chlorite/illite ratio and volcanic sources. Trace elements and REE data demonstrate |
