花坤铜多金属矿控矿条件与成矿规律浅析

Ore Control Factors and Metallogeny of the Huakun Cu-Polymetallic Deposit

花坤铜多金属矿区地处华北地台北缘燕山台褶带东部辽西台陷西侧朝阳穹褶断束中段,该穹褶断束呈北北东向展布,是辽西地区十分重要的构造—岩浆岩成矿带。在分析区域地质背景、矿床地质特征及主要控矿条件的基础上,总结了该区的成矿规律、找矿标志及找矿方向。通过综合分析认为在矿区具备矿源层—构造—岩浆岩"三位一体"的成矿条件较好的地段,找矿前景极佳,并经过钻孔验证,发现在花坤地区多处具有较好的找矿空间,如在和尚沟东山花岗斑岩与白云质灰岩接触带上48m处见矿。

The Huakun Cu-polymetallic deposit lies in the middle section of the Chaoyang dome-fold-fault beam as an important tectonomagmatic belt on the northern margin of the North China platform. The present paper has a discussion on regional geological setting, geological features, ore control factors and ore criteria of the deposit. There is good metallogenic geological condition and prospecting potential where three-in-one of source bed, structure and magmatic rock coincide.
