摘要：

Gold deposits were formed during two different geodynamic evolution stages of the Lesser Caucasus, starting with Mesozoic arc construction along the Eurasian margin, and followed by Cenozoic subduction-related to post-collision magmatism and tectonics during final Arabia Eurasia convergence and accretion. Gold deposits are of the low-, and intermediate- to high-sulfidation type, with the latter ones being associated with porphyry deposits. Some deposits could be analogous to transitional VMS-epithermal systems in the Late Cretaceous Bolnisi district and during nascent Jurassic arc evolution along the Eurasian margin, but require further investigation.
