Abstract: The study of the redissolution phenomenon of native gold from the ores of the Mazhala gold-antimony deposit in southern Xizang shows that the ore-forming matter from the gold-antimony deposit have been subjected to later low-temperature hydrothermal reworking. The later low-temperature hydrothermal activities are relatively weak,and not favourable for the enrichment of ore-forming matter. On the contrary,they would decrease the coloration of the mineral gold.
