摘要: 碧口地区地处摩天岭地块,是中国重要的金铜成矿远景区、矿集区。笔者以甘肃碧口地区金铜矿成矿地质背景、矿床地质特征为基础,结合典型矿床剖析,重点从矿床成因、矿床类型、矿床规模、赋矿层位、围岩性质和矿石特征等方面,总结了矿床的分布特征及规律,并提出了同类矿床的找矿标志和找矿潜力。Abstract: 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.
