  Abstract:  The Baia Mare metallogenetic district is one of Europe''s major metallogenic provinces and includes both gold and base-metal mineralization. Ores are associated with calc-alkaline Neogene volcanism. The calc-alkaline volcanism and associated metallogeny are related to an underlying pluton, (Borcoş et al., 1998). According to Giuşcă et al. (1973), metallogenetic activity corresponds to three distinct phases during the Sarmatian-Pontian. The ore deposits in the Baia Mare district are mainly epithermal, of low sulphidation type. They are predominantly base-metal, but distinct Au-Ag and Cu types also occur. The higher levels of the Cu and base-metal ores contain important quantities of Au and Ag. The most important deposit in the district is Baia Sprie one.
