Factors contributing to the formation of carbonated mineral water systems in Serbia [PDF]

open access: yesGeološki Anali Balkanskoga Poluostrva, 2012
There are more than 65 occurrences of carbonated mineral water (CMW) within the territory of Serbia. More than 93 % of these systems are found in the geotectonic unit referred to as the Vardar Zone and on the fringes of nearby units. To the east,
