Relationship Between Geological Setting ,and Genesis of Antimony Deposits

Abstract: Antimony deposits, among many other sulphide deposits, generally occur as vein type ,and found in closevicinity of volcanic areas. However, it is usually the case that the vein type of mineralization is related to volcanism,strata-bound type of mineralizotion is also expected to be formed in the same area. Subsequent geological events may causemobilization of antimony in .both types ,and change the original setting of the mineralization.Petrofabric analysis of stibnite ores, fluid inclusion studies ,and radiometric age determinations at the MurchisonRange, (South Africa) antimony deposits, revealed that the mineralization is contempereneous with the sediments ,andvolcanics. On the other hand, petrochemical analysis of stibnite ores ,and country rock at Niğde, (Turkey), antimonydeposits, showed that the ore was mobilized from a strata-bound source.
