Formation of orogenic gold deposits by progressive movement of a fault-fracture mesh through the upper crustal brittle-ductile transition zone [PDF]
Scientific Reports, 2022 Orogenic gold deposits are comprised of complex quartz vein arrays that form as a result of fluid flow along transcrustal fault zones in active orogenic belts.

Minerals of bismuth and antimony in original deposits of zarmitan gold zone, located in granitoid intrusion (Uzbekistan) [PDF]
E3S Web of Conferences, 2023 Modern methods of nanomineralogy (electron microscopy, electron probe microanalysis) were used to study the ores of one of the largest industrial facilities of Uzbekistan - the Zarmitan gold zone, which includes the Zarmitan, Urtalik, Guzhumsay deposits,

Lithospheric conductors reveal source regions of convergent margin mineral systems
Scientific Reports, 2022 The clean energy transition will require a vast increase in metal supply, yet new mineral deposit discoveries are declining, due in part to challenges associated with exploring under sedimentary and volcanic cover.

Lower crustal resistivity signature of an orogenic gold system
Scientific Reports, 2021 Orogenic gold deposits provide a significant source of the world’s gold and form along faults over a wide range of crustal depths spanning sub-greenschist to granulite grade faces, but the source depths of the gold remains poorly understood.
