Orogenic Gold And Geologic Time A Global Synthesis

Orogenic Gold And Geologic Time A Global Synthesis

Abstract. Orogenic gold deposits have formed over more than 3 billion years of Earths history episodically during the Middle Archean to younger Precambrian and continuously throughout the Phanerozoic. This class of gold deposit is characteristically associated with deformed and metamorphosed mid-crustal blocks particularly in spatial association with major crustal structures.

The Process Mineralogy Of Gold The Classification Of Ore

Abstract. The principal gold minerals that affect the processing of gold ores are native gold electrum Au-Ag tellurides aurostibite maldonite and auricupride. In addition submicroscopic solid solution gold principally in arsenopyrite and pyrite is also important. The main causes of refractory gold ores are submicroscopic gold the Au-Ag tellurides and very fine-grained gold 10 m locked in sulfides.

Extracting Gold Howstuffworks

Feb 23 2009 Smelting which results in nearly pure gold involves melting the negative terminals in a furnace at about 2100 degrees F 1149 degrees C. When workers add a chemical mixture known as flux to the molten material the gold separates from the metal used to make the terminals. Workers pour off the flux and then the gold.

Two explanations have been offered for this timing 1 because orogenic gold deposit formation requires accretionary tectonics the major periods of formation coincided with periods of continental growth Goldfarb et al. 2001 and 2 during the Phanerozoic increased ocean oxygenation facilitated uptake of gold in biogenic and diagenetic pyrite which became the gold source during later accretion
