Comparative Study on Typical Deposits in the Muruntau-Sawayardun-Kumtor Gold Belt

The gold belt in Southern Tianshan is an important gold resource, where a number of very large gold mines have been found. These deposits are similar in tectonic setting, ore-bearing rock series, host rocks, ore-controlling structures, ore body, ore type, main metallic minerals, gold-bearing mineral, metallogenic epoch and pattern of metallogeny. However, further analysis found that there had been some differences among them, such as structural location, material composition and wall rock alteration. Analyzing some basic metallogenic characteristics of this district, we believe that the formation of the gold belt is closely related to the formation and evolution of the southern Tianshan orogenic belt. The main mineralization is the Variscan hydrothermal mineralization related to the activities of granite, and therefore the deposits should be veinlet-disseminated type gold deposits. This is an important gold type with great prospecting potential in southern Tianshan.
