Abstract
Abstract The 40Ar-39Ar age method is employed in this work to analyze fluid inclusions of quartz in the ore bodies from the Kuo'erzhenkuola and Bu'erkesidai gold deposits in the Sawur gold belt, northern Xinjiang. The results show that the main mineralization occurred in 332.05±2.02–332.59±0.51 Ma and 335.53±0.32 Ma-336.78±0.50 Ma for the Kuo'erzhenkuola and Bu'erkesidai gold deposits respectively, indicating that the two deposits are formed almost at the same time, and the metallogenic time of the two deposits are close to those of the hosting rocks formed by volcanic activity of the Sawur gold belt. This geochronological study supplies new evidence for determining the timing of gold mineralization, the geneses of gold deposits, and identifies that in the Hercynian period, the Altay area developed a tectonic-magmatic-hydrothermal mineralization of the Early Carboniferous period, except the two known mineralization periods including the tectonic-magmatic-hydrothermal mineralization of the Devonian period and Late Carboniferous-Permian period.
