Name:
Named after Mooka Station on which it was found.
The term 'Mookaite' is an unofficial, locally coined name for a silicified porcelaniteI which forms in the weathering profile of a geological formation known as Windalia Radiolarite (WR), a Lower Cretaceous sedimentary unit that outcrops over much of the Carnarvon Basin in Western Australia.

Mookaite is variously, and incorrectly, described as chert, opalite, chalcedony or combinations of the three.

From a strictly geological perspective however, Mookaite is best defined as a silicified type of Radiolarite whose silification is opaline to chalcedonic.

[A.McLaren, www.eskimo.com/~knapper/mookaite.htm]

In Featherston et.al. Mookaite is described as being "dominantly massive ultrafine silica".
