Summary: Three secondary mineral assemblages formed at the fast-spreading Mendoza Rise: trioctahedral chlorite and talc, goethite and smectite, and calcite and celadonite. These sequences were affected by T and state of oxidation. At this site celadonite represents the end stage of the hydrothermal alteration which lasted 10-16 m.y. after basalt crystallization at the ridge crest.
