Placer gold deposits are abundant in Mongolia and form through endogenic and exogenic processes. Deposits are classified into four major genetic types: (1) eluvial-weathering zone, (2) deluvial, (3) proluvial, and (4) alluvial. The most economic deposits are often sourced from upper Cretaceous rocks and formed in late Cenozoic alluvial fans (Liskun and

Editor’s note: Smimov uses the weathering definition of eluvial, meaning “an accumulation of rock debris produced*in-place by decomposition or disintegration of rock; a residue.” Two other terms in Smimov’s classification are not in common usage in North America nor in North American placer classification schemes By Russian definition, diluvium is an ...

Placer deposits provided early man with the first samples of gold and thereafter have accounted for a large production of the metal. If we include the Witwatersrand and other quartz-pebble conglomerates as fossil placers or modified placers, the placer type of auriferous deposit has provided more than two thirds of the world’s store of gold, about 80 ×
