Abstract

The Allšar Au-Sb-As-Tl mineral deposit, Macedonia, occurs in the southern part of the Vardar zone. The deposit carries Carlin-type of mineralization hosted by calcareous sedimentary complex. Mineral assemblages and alterations display characteristic zonal distribution. According to the fluid inclusion data, mineral deposition occurred as a result of cooling, dilution and neutralization of the ore-bearing fluids. Neogene magmatism (4.6 to 5.8 Ma) served as the heat source responsible for driving convective hydrothermal circulation at the Allšar deposit.
