The term ‘Mookaite’ is an unofficial, locally coined name for a silicified porcelanite which forms in the weathering profile of a geological formation known as Windalia Radiolarite (WR), a Lower Cretaceous siltstone that outcrops over much of the Carnarvon Basin in Western Australia. The Aboriginal term “Mooka” means “running waters” and refers to the numerous springs that feed into this area. Mookaite was formed as the skeletal remains of radiolaria, microscopic protozoa with a hard silica shell, were deposited over millennia as sediment in shallow areas of sea beds. As waters receded, the remains were solidified by additional silica carried in groundwater, along with minerals that produced its beautiful combinations of red, burgundy, mustard-yellow, cream, white, brown, mauve and purple.
