  • Intracratonic geodynamics

    Geodynamic concepts of deformation and metamorphism of continental lithosphere are dominated by the effects of subduction, accretion or collision along the margins of continental lithospheric blocks. Yet it is becoming increasingly apparent that suture zones, presumably represe...

  • Mass Anomaly Depth Estimation From Full Tensor Gradient Gravity Data

    We introduce an algorithm that uses an accumulation method over a volume to determine the potential locations of mass anomalies. Lines are cast through the volume according to physical properties of the FTG tensor, and votes accumulated from all such lines. Local maxima of the...

  • Partial melting of the Archaean Thrym Complex of southeastern Greenland

    High-grade Archaean rocks of the remote Thrym Complex of southeastern Greenland expose a lower crustal section that formed at a depth of >30 km at temperatures reaching 1000°C and pressures approaching 1.5 GPa. The complex is part of the North Atlantic Craton, which is b...

  • Morphology and microstructure of chromite crystals in chromitites from the Merensky Reef (Bushveld Complex, South Africa)

    The aim of this study is to expand the knowledge of chromite textures, crystallographic orientation, grain morphology, composition and intra-grain microstructures within the Merensky Reef chromitites. New microstructural data (by electron backscatter diffraction analysis) are c...

  • Visualising Full Tensor Gradient Gravity Data using Texture and Colour Cues

    We present an algorithm for visualising FTG gravity datasets which displays local lateral orientations encoded in the FTG data. It uses a colour map to highlight geologically significant structures such as linear features and radially symmetric points by identifying different g...

  • Option valuation and accounting for contingent consideration in mineral sector acquisitions

    Vendor consideration on acquisition of mineral sector companies/projects may include shares and/or options contingent on achievement of uncertain milestones either financial (specified levels of future profit, share price etc) or physical (delineation of specific levels of mine...

  • Mineral potential mapping in frontier regions: A Mongolian case study

    The quality of a mineral potential map is dependent on the quality of the input data used in the analysis. In frontier regions or those with limited or no exploration history, datasets are often of questionable quality, and are generally incomplete with data missing either due...

  • High-grade Iron ore at Windarling, Yilgarn craton: a product of syn-orogenic deformation, hypogene hydrothermal alteration, and supergene modification in an Archean BIF–basalt lithostratigraphy

    Banded iron formation (BIF) hosted iron ore deposits in the Windarling Range are located in the lower greenstone succession of the Marda-Diemals greenstone belt, Southern Cross domain, Yilgarn  craton, and constitute a total hematite-martite-goethite ore resource of minimu...

  • Komatiite Magmas and Sulfide Nickel Deposits: A Comparison of Variably Endowed Archean Terranes

    Komatiites are found in most Archean granite-­‐greenstone terranes, but sulfide Ni mineralization associated with these rocks has a very biased distribution. The global endowment of sulfides Ni in Archean komatiites is overwhelmingly dominated by the Kalgoorlie terrane of the E...
