What is an orogenic gold deposit

[mkjuk]

all i know is that it is some kind of gold mine

Please help

Orogeny is the process of mountain formation, especially by a folding and faulting of the earth's crust.

This will explain more

Orogenic gold deposits are typically adjacent crustal shear zones which themselves are devoid of significant mineralization. Mapping of fluid flow using oxygen isotopes and 3D modeling of transport and reaction show that the crustal shear zones were hydraulic drains across a low permeability crustal layer. The crustal shear zones draw gold-bearing hydrothermal fluids from the network of smaller shear zones that host mineralization.

put simply....

Rapid plate convergence events will bury a pile of volcano-sedimentary rocks causing a short-lived pulse of metamorphic fluid to rise along zones of transient permeability. This results in a fluid wave that propagates upward carrying gold to the mineralized area. Earthquakes along crustal shear zones cause dilation near jogs that draws fluids and deposit gold in an interconnected network of shear zones

put even more simply...

its a huge hole in the earths crust filled with gold.

lol good luck finding one....
