Australian scientists discover new corals on most comprehensive deep-sea study of GBR
For the first time, scientists have viewed the deepest regions of the Great Barrier Reef Marine Park, discovered five undescribed species consisting of black corals and sponges, and recorded Australia's first observation of an extremely rare fish. They also took critical habitat samples that will lead to a greater understanding of the spatial relationships between seabed features and the animals found in the Coral Sea.
International geoscience collaboration to support critical mineral discovery
Links Document: Report (1.87 MB pdf) Open Access Version: Publisher Index Page Download citation as: RIS | Dublin Core Abstract First posted July 8, 2020 The importance of critical minerals and the need to expand and diversify critical mineral supply chains has been endorsed by the Federal governments of Australia, Canada, and the United States.
Exposed soil and mineral map of the Australian continent revealing the land at its barest
Abstract Multi-spectral remote sensing has already played an important role in mapping surface mineralogy. However, vegetation – even when relatively sparse – either covers the underlying substrate or modifies its spectral response, making it difficult to resolve diagnostic mineral spectral features.

Archaean continental spreading inferred from seismic images of the Yilgarn Craton
On the early Earth, oceanic plateaux similar to present-day Iceland are thought to have evolved into less dense microcontinents as they thickened by continued melt intrusion and crustal fractionation. These earliest continents may have been so weak on a hotter Earth that they collapsed laterally in response to thickening by further magmatic growth or tectonic imbrication.
