Outcrop of the so-called "Capo Bianco Aplite", the oldest intrusive unit (≈8.4 Ma) of the central-western Elba magmatic complex, in a marine cliff at Capo Bianco, west of Portoferraio. This rock was emplaced as a thin sill (≈100 m thick, 3.5 km wide) at a very shallow crustal level (≈ 2.5 km depth) into Cretaceous flysch. It is a peraluminous alkali feldspar granite; its high boron content is indicated by the widespread occurrence of tourmaline orbicules, varying in sizes from millimetres to many centimetres.
