✦ Synopsis

The Muratdagi region is rich in antimony deposits having the following common characteristics: post Miocene age, location on the down-thrown blocks next to normal faults, in the vicinity of active or fossil thermal springs, and in contact with carbonate rocks. The isotopic composition of -7%o. SMOW of the mineralizing fluid calculated from the measured 6tso of quartz and the fluid inclusion microthermometry, is indicative of meteoric water origin. The 613C of the inclusion CO 2 of -19.1 to -25.4%0 PDB is indicative of interaction with organic material-graphite. The 634S of stibnite -3.6 to -0.7%0 is, in view of the mineral assemblage, indicative of magmatic origin of the sulphur. A tightly confined set of structural, lithological, hydrological and geochemical features define a sequence of geochemical processes; formation of acid and reducing fluid, leaching and transport of antimony complexes and precipitation of stibnite within defined lithological units. The set of processes seems to have taken place within a space of 5000 m lateral and 1000 m vertical extension.
