Editorial: Orogenic gold deposits.

This article is an editorial on orogenic gold deposits, which are found in metamorphic terranes and contribute to approximately one-third of the world's total gold production. The research topic focuses on understanding the geological processes involved in the formation of these deposits, including the source of metals and fluids, alteration of mineral assemblages, and the role of different geological terranes. The papers in this research topic cover a range of topics, from detailed mineralogical analysis to regional-scale synthesis. The article acknowledges that there is still debate surrounding the models explaining the sources of metals and fluids in orogenic gold deposits. [Extracted from the article]
