Secondary mineral deposits have played an important role in the global mineral resource economy for over 50 years, with lateritic Au, Al, Fe and Ni deposits having a significant input to global metal production and reserves. In the Yilgarn Craton of

Gold nuggets have long captured the imagination of geologists, prospectors and the public alike, but their origin remains disputed. Supporting a supergene origin, most gold nuggets in Australia have been found at or near the soil surface. Many are in

This essay traces the development of geochemical exploration from its early beginnings in the modern era during the 1930s, concentrating especially in its application to deeply weathered terrain in the tropics and sub-tropics. Following promising res

Australia experienced a major increase in gold production during the 1980s, and this is reflected in the production of ~250 tonnes of gold per annum since then. Much of the production has come from the Archean Yilgarn Craton of Western Australia, and

Nickel laterite ores account for over 60% of global nickel supply. They are the product of intensive deep weathering of serpentinites under humid tropical conditions. Nickel is concentrated to over 1.0 wt% and is hosted in a variety of secondary oxid

The geomorphology of much of sub-Saharan West Africa is dominated by the presence of plateaux and plains with ferruginous and, locally, aluminous (bauxitic) duricrusts. The plateaux occur at different elevations and have been correlated as two or mor

Archibald Liversidge FRS (University of Sydney 1874–1907) had a long-term interest in the origin of gold nuggets, a matter of considerable contemporary debate. He conducted pioneering studies on the petrography of nuggets, noting their polycrystall
