Orogenic deposits are the source of much of the world’s gold. Here is a look at the components that make up orogenic deposits.
Orogeny, or mountain formation, is the result of intense upward displacement of the Earth’s crust. Formed more than 3 billion years ago, orogenic gold deposits — also known as mesothermal deposits — are characteristically associated with deformed and metamorphosed mid-crustal blocks; more specifically, they are in spatial association with major crustal structures. Such deposits are the source of much of the world’s gold production.
Here is a look at the components that make up orogenic deposits:
