May 01, 2018· Good correlation between the timing of mesozonal shear zone-hosted vein-type gold deposits and times of widespread orogeny has long been recognised and formed the base for their classification as "orogenic-type" (Goldfarb et al., 2005, 2001).Notably, the largest peak in the age distribution of orogenic gold production (in terms of tonnage) is …
Orogenic lode gold deposits range in age from Archaean (such as the Barberton district in South Africa) to Mesozoic–Tertiary (such as the Mother Lode district). There remain a number of theories for their origins, but all seem to be associated with major accretionary orogenic events (plate collisions) and occur near major translithospheric structures …
