Abstract: The comparative study of the mineralized horizons of the Boka, Xintian and Xiaoliukou gold deposits led us to conclude that the all the mineralized horizons should be assigned to the Pingdingshan Formation in the Tangdan Group. The Pingdingshan Formation as the host horizonsis has provided most ore-forming matter for gold mineralization. The Boka and Xintian gold deposits belong to the tectonically altered gold deposits. Particular attention will be drawn to stratigraphy, magmatic rocks, faults and alteration for future gold prospecting in the Pingdingshan Formation in the Huidong-Dongchuan region. The potential prospect areas comprise the Xintian gold deposit and its surrounding areas, the southern part of ore-controlled shear fractured zone of the Boka gold deposit, and Xiaoliukou-Renmin'ao-Yanziyan areas.
