Relation between Shuiquangou Alkali Complex and Gold Deposits in Northwestern Hebei Province, P.R. China

摘要

The Shuiquangou alkali complex is one of representative example of concentration region of gold deposits in northwestern Hebei Province, which has the largest scale, the most rock types and the most complicated genesis. Through comprehensive analysis of the rock types, mineral composition, chemical constituents, genesis and formation age, the Shuiquangou alkali complex is the products of multiple magma reformation that is controlled by the Zhangjiakou-Xuanhua mantle branch structure. The diagenetic process of the Shuiquangou alkali complex is also the ore-forming process of Au that through activating, migrating and enriching.
