Controversy has surrounded the formation of the largest gold deposits on Earth in Witwatersrand, South Africa. AsFrimmelexplains in his Perspective, the report byKirket al.should lay the controversy to rest by providing age data for the gold. The results indicate that the gold was brought into...
GOLD: History and Genesis of Deposits is the product of an effort by the Society of Economic Geologists to publish materials that will expand knowl edge concerning timely, specific topics important to the study of economic geology and to economic geologists. A volume on gold was selected for...
The eastern North China craton contains the largest association of gold deposits in China. Hundreds of gold deposits of different scales, commonly in groups or belts, constitute seven subclusters. In contrast, there are no industrial gold deposits in the neighboring areas of the UHP Sulu region ...

A simple classification: gold-only and gold-plus deposits We propose that a useful high level classification of gold deposits is on the basis of contained base metals. Application of the classification relies upon a single question: The majority of gold deposits, referred to as gold-only, do ...
Iron oxide-copper–gold (IOCG) and magnetite-(apatite) (MtAp) mineralization are a controversial group of ore deposits that share some common characteristics, such as the abundance of iron oxides and are associated with calcic-iron-alkali alteration. The largest deposit on Earth is the world-cla...
