LATE-OROGENIC GOLD DEPOSITS IN EGYPT

Mining science and technology, 2018
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. Granitoid massifs are widely developed within this tectonic zone.

Mayum: an orogenic gold deposit in Tibet, China

Ore Geology Reviews, 2009
Abstract Located in western Tibet, China, the Mayum orogenic gold deposit was discovered in 2002 with estimated resources of > 80 tonnes gold. The gold mineralization is hosted by Neoproterozoic–Cambrian schists, and is controlled by nearly parallel E–W trending bedding-concordant fracture zones.

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

A Database of Low‐Temperature Thermochronology in East Asia

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
Spatial distribution of low‐temperature thermochronology samples in East Asia. ABSTRACT The low closure temperature of the dating system in low‐temperature thermochronology allows shallow crustal movements to be recorded. In recent decades, this approach has been used extensively in studies of orogenic belt exhumation, sedimentary basin evolution, and ...
