The Zhangjiapingzi gold deposit of Mianning County, Sichuan province is located in a set of green schist series, altered basalt and volcanic breccias containing metasomatic- altered dolomite of T 2-3. Gold mineralization occurs mainly in alteration zones due to the influence of the Jinhe- Chenghai fault. Through researches, the metallogenic materials of this deposit are derived from deeper part of the earth, which underwent intrusion of deep polymetal and Au-rich mantle fluid in Middie-Late Yanshanian period, resulting in metasomatism and enrichment of Au occurring at favorable structures. During the Himalayan Epoch, a hydrothermal process causing Au enrichment occurred again, which formed gold deposits at some favorable positions by enrichment further.
