Geological Characteristics and Ore-prospecting Potential of Gold-Copper Deposits in Bikou Area, Gansu Province

The Bikou area is located in the Motianling block of Gansu Province, which is an important copper-gold metallogenic prospective province and ore-centralization area in our country. Based on the geological setting and characteristics of the gold-copper deposit, the genesis, type and scale, and ore-bearing horizon, surrounding rock properties and ore features of typical mineral deposits have been analyzed. And then, the distribution of gold-copper deposits in Bikou area has been summarized in this paper, and the indicators and ore prospecting potential of the similar deposits have been pointed out.
