  • Heavenly Bodies

    It may be beyond the realms of direct field study, but the geology of Mars, is surprisingly well documented. Orbiting satellites have imaged the surface of the planet across a range of geologically sensitive wavelengths, NASA's Landers and Rovers have directly observed - and an...

  • The ongoing search for Hadean crust on Earth

    The familiar concentric layer cake structure of the Earth depicted in textbooks formed within a few hundred million years of the accretion of the planet. This is when the metallic core segregated, the oceans condensed, the atmosphere outgassed and the first rocky crust formed....

  • Grade Expectations

    Publicly released cost information from 53 operating gold mines in Australia (50 mines) and New Zealand (3 mines) reveals a number of insights into 2013 production costs - pointing in particular to geological factors, rather than the commonly expected grade effect as of greater...

  • Chasing Footprints of an Elusive Quarry

    Remobilization of metals during post-deposition hydrothermal alteration of magmatic sulfide ores has the potential to produce distinct haloes far greater in scale than the source ore body. Recognition of such dispersed signatures may dramatically enlarge the detectable footprin...

  • A Social License to Undertake Research

    Modern research science is a capital-intensive industry. Scientific resources and agencies are concentrated in wealthy developed nations with the economic and infrastructure base to support such fundamental endeavours. Nature, however, respects no such distinctions - and we com...
