Abstract
Studies of the morphology and other properties of the gold particles in the fossil placer gold deposits of the Witwatersrand provide fascinating glimpses of the conditions under which they were formed. In particular they indicate that in some areas primitive plant life on the deltas on which the gold was deposited acted not only like the legendary golden fleece in concentrating fine gold particles, but probably also reacted biochemically with these particles to determine the forms in which gold is observed in the carbonaceous remains of this plant life today.
