Late-orogenic gold deposits of Egypt
Egypt belongs to states developing its mineral resource base. Gold-bearing territory of Egypt is located within the Nubian-Arabian shield in the Neoproterozoic collision zone of transverse thrusts.

A review of the localities in continental rocks where H2-rich gases have been reported, showed that they are mainly located near orogenic gold deposits.

Attempts to geochemically distinguish between metamorphic-hydrothermal systems that form orogenic gold deposits and both reduced and oxidized magmatic-hydrothermal systems using isotopes or metal associations have proven ambiguous, particularly for ...

The Metallogenic Setting of Terminal Orogenic Gold Deposits
This thought project is focused on the time and place of gold concentration within orogens, the most complex of the tectonic settings resulting from plate interactions.

Metabasalts as sources of metals in orogenic gold deposits
Although metabasaltic rocks have been suggested to be important source rocks for orogenic gold deposits, the mobility of Au and related elements (As, Sb, Se, and Hg) from these rocks during alteration and metamorphism is poorly constrained. We investigate the effects of increasing metamorphic grade on the concentrations of Au and related elements in a ...

Trace elements in pyrite from orogenic gold deposits: Implications for metallogenic mechanism
Pyrite, one of the most important sulfides, is widely spread in various types of gold deposits, and its trace element geochemistry is extensively useful for revealing the physicochemical conditions of ore-forming fluid, and thus constraining the ore ...

Prospectivity analysis of orogenic gold deposits in Saqez-Sardasht Goldfield, Zagros Orogen, Iran [PDF]
Abstract Diverse deposit-types or mineral systems form by diverse geological processes, so translation of knowledge about the controls of mineralization acquired from the 4D geological modeling into 2D spatial predictor maps is a major challenge for prospectivity analysis.
