This Open-File report is complemented by a poster-size geological map of the world, Open-File report 4893: Gold deposits and gold districts of the world, showing locations and sizes of all gold deposits and gold districts spread across the globe. It also displays enlargements of key goldproducing areas (such as the Abitibi Belt and Western Australia) and detailed economic figures current to at least the end of December 2002. 
These products are companions to the Open-File report 4896: Gold deposits of Canada, a database comprising referenced and detailed geological, geographical and economical information on 128 gold deposits, and to the Open-File report 4894: Gold deposits and gold districts of Canada, a poster-size map of Canada showing the location and size of all important gold deposits, as well as enlargements of key gold districts.

The distribution of gold in the lithosphere bears critically on models for gold ore deposits. One group of workers advocates derivation of gold from large masses of rock through fluid-rock reactions in the deep crust (Kerrich, 1983; Groves and Phillips, 1987; Colvine et at., 1988) while others stress the importance of relatively restricted petrogenetic groups of rocks termed source rocks that concentrate gold above the norm (Viljoen et al., 1970; Keays, 1984). It is therefore important to know the average gold contents for rock types of the lithosphere, and what concentrations are potentially indicative of mineralization. Tilling et at. (1973) noted that unaltered igneous rocks generally have less than 5 parts per billion (ppb) gold and that 10 ppb is exceeded only rarely. A survey of more recent data presented here confirms that statement. As ore deposits may concentrate gold 104 times the rock background, gold contents of only a few tens of ppb may indicate ore-forming processes.

Gold, a chemical element with the symbol Au, is a highly sought-after precious metal, having been used as money, in jewelry, in sculpture, and for ornamentation since the beginning of recorded history. The metal occurs as nuggets or grains in rocks, in veins and in alluvial deposits. Gold mining consists of the processes and techniques employed in the removal of gold from the ground. There are several techniques by which gold may be extracted from the Earth. Since the 1880s, South Africa has been the source for a large proportion of the world’s gold supply, with about 50% of all gold ever produced having come from South Africa. Other major producers are the United States, Australia, China, Russia and Peru. The world's oceans also hold a vast amount of gold, but in very low concentrations. At current consumption rates, the supply of gold is believed to last 45 years. This book will present current research on gold mining including methodologies for discovering new deposits of gold as well as economic and environmental issues. <...>
