Regolith profile, mineralogy and geochemistry of the Weipa Bauxite, northern Australia
The regolith profile at Weipa is of two types. At Andoom, to the north of Weipa township, a 30 m profile overprints and overlies sediments of the Rolling Downs Group. At a depth of 23 m saprolite gives way to a Plasmic (pallid) Zone of kaolinite + quartz, which becomes mottled above 12 m. The degree of induration of the Mottled Zone increases upward to form a discontinuous and irregular Transition Zone about 1 m thick at the top of the wet season water-table and at a depth of about 4 m.
