%X The Amanay Massif in the island of Fuerteventura is built up by a series of hypoabyssal subvolcanicalkaline rocks (ultramafics, gabbros and syenites) intruded by several basalticdyke-swarms of regional extension. The ultramafic rocks form a Pyroxenite-CarbonatiteComplex surrounded by the corresponding feldespatic net-work and associated fenites.The regional swarms of dykes, whose main structural trends are NNE-SSW, N-60-70º andN-115-120° seems to change gradual/y in the southern areas of the massif to lava sheetsthat mark the upper levels .of the formation. The last event in the area is represented by afew remanents of a formerly extenser coverture of horizontal lava flows that líe unconformabilyover the dyke-swarm formation.
