Adakitic signal linked to Gondwanan porphyry type deposits from the Andean Frontal Cordillera of Argentina

Source and deposition age of the Dialé-Daléma metasedimentary series (Kédougou-Kéniéba Inlier, Senegal) constrained by U–Pb geochronology on detrital zircon grains

The Dialé-Daléma metasedimentary series is exposed in the Kédougou-Kéniéba Inlier that corresponds to the northwestern branch of the Eburnean orogenic belt in the southern West African Craton. Here we conducted a U–Pb geochronological st...

A new fluid-flow model for the genesis of banded iron formation-hosted martite-goethite mineralization, with special reference to the north and south flank deposits of the Hamersley Province, Western Australia

The North and South Flank deposits are located on the flanks of the Weeli Wolli anticline at Mining Area C in the central Hamersley Province. Supergene martite-goethite mineralization is hosted within the Marra Mamba Iron Formation and is developed over a strike length of more...

Evidence for a serpentinized plate interface favouring continental subduction

The dynamics of continental subduction is largely controlled by the rheological properties of rocks involved along the subduction channel. Serpentinites have low viscosity at geological strain rates. However, compelling geophysical evidence of a serpentinite channel during cont...

Modern Management in the Global Mining Industry

Towards producing mineral resource-potential maps within a mineral systems framework, with emphasis on Australian orogenic gold systems

Discovery of new deposits has slowed dramatically since the beginning of the 21st century despite increased expenditure. Targeting below deep, complex cover is recognised as key to opening up new search-spaces and re-invigorating exploration success. Existing techniques and tec...

Spinel, olivine, and pyroxene chemistry of the Eoarchaean Manfred Complex (Yilgarn Craton, Western Australia), with implications for the tectonic setting of Archaean layered mafic intrusions and the stabilisation of continental nuclei

Anorthosite complexes are distinctive components of Archaean cratons and their petrogenesis has implications for ancient mantle evolution, early Earth geodynamics, and growth of continental crust. However, the origin and tectonic setting of Archaean anorthosites and their compl...

Rare Earth Permanent Magnets and Their Place in the Future Economy

Due to their rising economic importance as an enabling technology for the energy transition from fossil fuels to renewables and to their ubiquitous use in the miniaturization of electronic...

Multidisciplinary study of a complex magmatic system - The Savannah Ni-Cu-Co Camp, Western Australia

The Savannah (formerly Sally Malay) Ni-Cu-Co Camp is composed of a group of mineralised intrusions (Savannah and Savannah North) and petrologically similar mafic-ultramafic intrusions without known mineralisation (Sub-chamber D, Dave Hill, and Wilson's Creek). The results of a...

Petrological and geochemical study of Birimian ultramafic rocks within the West African Craton: Insights from Mako (Senegal) and Loraboué (Burkina Faso) lherzolite/harzburgite/wehrlite associations

In Archean and Paleoproterozoic greenstone belts, ultramafic (UM) rock occurrences are commonly found in close association within basic and differentiated magmatic series. In the Kedougou-Kenieba Inlier (West African Craton), UM rocks are interbedded within the Birimian (2.1 Ga...
