Abstract

The Altai region of Xinjiang represents one of the most significant gold metallogenic belts in China. In recent years, an increasing number of gold deposits have been identified as intimately associated with intermediate-acidic intrusive rocks, particularly granites. The Altai region extensively exposes multi-episodic, multi-source granitic plutons exhibiting distinct spatiotemporal distribution characteristics, which are closely related to gold mineralization. Based on a systematic review of previous research findings, combined with the orogeny, magmatism, and tectonism of the Altai orogenic belt, this paper classifies four representative gold deposits that exhibit close spatiotemporal relationships with granites in the Altai region. The primary characteristics of orogenic-type, low-temperature epithermal-type, and subvolcanic-structural alteration rock-type gold deposits are summarized, aiming to provide theoretical references and practical guidance for exploration prediction of granite-related gold mineralization in Xinjiang.
