Identifier: http://hdl.handle.net/1959.14/214115
Description: The progressive μ¹⁴²Nd decrease in early Archean rocks from +20 to 0 between 3.9 to 3.6 billions years (Gyr), with rocks younger than 3.5 Gyr showing no μ¹⁴²Nd anomalies, is thought to indicate the ef... More

Identifier: http://hdl.handle.net/1959.14/150379
Description: A detailed deep 3D geological model is an important basis for many types of exploration and resource modelling. Renewed interest in the structure of the Sydney Basin, driven primarily by sequestration... More

Identifier: http://hdl.handle.net/1959.14/170634
Description: Mixed-habit diamonds are a relatively understudied subset of samples, considering the amount of research that has been carried out on these vessels from the mantle. They exhibit periods of growth duri... More

Identifier: http://hdl.handle.net/1959.14/101436
Description: Following the crystallization of a magma ocean, the martian mantle probably underwent an overturning event, but its initiation, timing and geochemical consequences are poorly constrained. Isotopic dat... More

Identifier: http://hdl.handle.net/1959.14/191175
Description: The distribution of lamprophyre-hosted Neoarchean diamond deposits in the southem Superior Province, Canada, corresponds to that of coeval giant(> 100 tAu) examples of "orogenic" gold deposits, which ... More

Resource Type: journal article
Identifier: http://hdl.handle.net/1959.14/21178
Description: Plate tectonics on Earth is driven by the subduction and stirring of dense oceanic lithosphere into the underlying mantle. For such a regime to exist on any planet, stresses associated with mantle con... More

Resource Type: journal article
Identifier: http://hdl.handle.net/1959.14/20471
Description: Standard models for a warm, wet early Mars require a significant CO₂-H₂O atmosphere in the past. The source for these phases is assumed to be volcanic degassing. However, no consistent, dynamical mode... More
