Nota sobre les roques hipabissals de la Serra de Tramuntana de Mallorca: algunes característiques petrogràfiques y geoquímiques

Some diabase and more leucocratic dykes found in Mallorca demonstrate the existence of subvolcanic or hypoabyssal on this island. All these outcrops are always found inside the triassic materials, and and thus may be directly related to the upper triassic volcanism. Although some of the studied rocks have evident alkaline affinities (with ne and ol in the CIPW norm), others display greater diversity, from transitional (with ol and hy ) to subalkaline types (with hy and Q in the norm)
