clay mineral sedimentation in the ocean

The clay mineralogy of 235 surface sediment samples from the western Indian Ocean reveals many sedimentary sources and processes 1 some areas mainly in the central Indian Ocean where very little sediment transport is involved have smectiterich clays derived from the alteration of in situ submarine basalts 2 In many other areas the mineralogy is significantly influenced by several
