Abstract:
Features of associations of newly formed minerals in Oligocene basalts from the Reykjanes Ridge (DSDP Hole 407), which consist in wide development of celadonite-glauconite group minerals, as well as saponite, cristobalite and specific Fe-Si formations is shown. Detailed mineralogical and geochemical characteristics of these newly formed minerals are reported. It is firstly shown that at underwater alteration of basalts not only celadonite can be generated, but also glauconite. Dependence of secondary mineral composition from petrochemical features of original basalts and from their permeability is revealed. It is concluded that complexes of secondary minerals formed during alteration of basalts with similar petrochemical characteristics in the ocean and on the continent are different.
