Geological Characteristics and Prospecting Marks of the Sarbulak Gold Deposit in Fuyun, Xingjiang

Sarbulak gold deposit is situated in northwest Sarbulak-Akhtarskaya fault zone of northeast Moledierbasitaofu syncline, which lies in the Karatongk island arc belt on northeast part of Junggar Basin. The ore body is dominated by a secondary fault i.e. Sarbulak ductile shear zone, which is obviously controlled by formation lithology and tectonics. The ores of the deposit are altered rocks with major alterations as arsenopyritization, pyritization and silication. Comprehensive analysis has shown that in the early stage, the gold deposit was metamorphic hydrothermal protore, and after many phases of geothermal events, underground hydrotherm experienced multiple alteration superpositions to form the gold deposit. This paper has also summarized the prospecting marks from four aspects, including strata lithology and tectonics, limonite gozzan, surrounding rock alteration, and geochemical anomaly.
