They argue that gold mineralization is synmetamorphic, and ore-forming fluids are metamorphic fluids related to metamorphism in a regional orogenic process. On the other hand, many researchers do not agree with this model because the age of gold mineralization in Murauntau is about 287.5 ± 1.7 Ma, which overlaps with the …
