A large variety of hydrothermal ore deposits, such as porphyry Cu-Mo-Au systems and lode gold deposits, are characterized by extensive potassic alteration in the form of K-feldspar and mica-group minerals (Sillitoe, 1972, Sander and Einaudi, 1990, McCuaig and Kerrich, 1998).This widespread alteration indicates the abundance of K + in the ore-forming fluids of …

Copper is the metal most commonly alloyed with gold. Manufactures express the proportions of gild in an alloy by: (1) karats or (2) fitness. The karat system, which is usually used for jewellery and ornaments, divides the alloy into 24 parts.
