Archeological and Historical Investigations in Samanà Dominican Republic #227752

No traces of recent volcanic activity appear on the peninsula; the oldest rocks are metamorphic and igneous and form a group of schists, shales, serpentines, limestones, and conglomerates. On the south shore of Samana Bay the mountain ridges east of Sabana de la Mar are composed of sedimentary schists, while west of that point limestones prevail.
