WebOn the contrary, Ligurian Ophiolites are often associated with remnants of the continental crust, and analogously the Betic Ophiolites locally present some indices of crustal assimilation, probably deriving from basement rocks of their continental margin, indicating in both cases (1) vicinity of the continental margin at least during the first ... WebThis phase of continental building is also characterized by a huge magmatism, intrusive and eﬀusive, firstly calc-alkaline, then potassic and finally alkaline. Part of the magmas is anatectic, resulting in the recycling of older continental crust, but another part is mantle-derived, thus adding fresh material to the continent.
