Abstract:

Sepiolite has been found in samples dredged from the Mid-Atlantic Ridge. The mineral is intimately associated with laminated clay and coccolith ooze, both containing clinoptilolite one sample contained chert. Serpentine was recovered in the same dredge, but the sepiolite seems to have formed by the reaction of Mg in solution with SiO2 liberated during alteration of silicic volcanic ash, rather than by direct alteration of the serpentine.
