It was created in 1958 to promote speleology, scientific investigation, and the fostering and preservation of caves in Western Australia. [2] As Western Australia's largest caving group, [3] WASG continually arranges caving expeditions to undertake cave surveys, implement rehabilitation measures, and work to enable better access to caves.

Quartz-pebble metaconglomerate (Jack Hills Quartzite), the rock type that contains Earth's oldest dated mineral grains (detrital zircon) Detrital zircons with ages greater than 4 billion years old have been found in these rocks, and a 4,404 ± 8 million year old zircon was found at Erawandoo Hill; [4] this is the oldest dated material originating on Earth; the date is in the Cryptic era of the ...
Basic geological regions of Australia, by age. The large brown region in the lower left of the continent constitutes the Yilgarn Craton. The Yilgarn Craton is a large craton that constitutes a major part of the Western Australian land mass. It is bounded by a mixture of sedimentary basins and Proterozoic fold and thrust belts.
The Geological Survey of Western Australia is an authority within the Department of Mines and Petroleum of the Government of Western Australia that is responsible for surveying and exploration of Western Australia's geological resources. The department provides information to industry, technical support and professional guidance to government ...
Goethite and hematite (U-Th)/He geochronology yields ages between ca. 18 to 4 Ma for the ferruginization of the Yandi and Robe River CIDs. [1] [2] Although these ages agree with the generally accepted Miocene model age for the formation of the western Australian CIDs, [3] some researchers have questioned the validity of these ages on the basis of the authors' geologic sampling and statistical ...
