Gold deposits in the sialic belts are divided into the orogenic and intrusion-related from this time. Epithermal Au-Ag mineralization is added to these two types, since the Middle Paleozoic, and most abundant in the Late Mesozoic - Cenozoic. This evolution is the result of differentiation of the mineral composition of orogenic gold deposits in time. For example, tourmaline is a common mineral ...

Gold in Minerals and the Composition of Native Gold

GOLD IN MINERALS AND THE COMPOSITION OF NATIVE GOLD By ROBERT S. JONES and MICHAEL FLEISCHER ABSTRACT Gold occurs in nature mainly as the metal and as various alloys. It forms complete series of solid solu­ tions with silver, copper, nickel, palladium, and platinum. In association with the platinum metals, gold occurs as free gold as well as in solid solution.
