辽宁花坤金-银多金属矿地质特征及找矿标志

Geologlcal characteristics and prospecting indicators of Huakun gold silver polymetallic ores in liaoning province

辽宁花坤金-银多金属矿成矿条件优越,控矿因素复杂,矿化分布普遍,矿床类型较多,是辽西地区重要的找矿远景区。为了使该区的找矿勘查更有所突破,通过对已往的找矿成果资料进行全面的收集、整理及研究,总结得出,花坤金-银多金属矿的赋矿地层为蓟县系雾迷山组碳酸盐岩建造;控矿构造为独特的“莲花状旋卷构造;成矿与燕山晚期花坤杂岩体具有明显的时空关系和成因联系;矿区具备矿源层-构造-岩浆岩“三位一体”的成矿地质条件。找矿前景十分广阔,有望成为中-大型找矿勘查基地。

Hu＇akun area is an important prospect in west Liaoning province where the ore controlling factors are complicated with widespread mineralization and various deposit types and the ore forming conditions for the Huakun gold-silver polymetallic deposit are superior. In order to make an even bigger breakthrough in ore prospecting, a summary was made through comprehensive accumulation, analysis and research of the existing prospecting data. It is concluded that the ore bearing strata of the Huakun gold-silver polymetallic deposit are carbonate rock formation of Wumishan Group of Jixian Series; ore controlling structure is a unique lotus flower shape rotational structure; Mineralization showsclear time-space relationship and genetic association with Later Yanshanian Period Huakun complex; There is ＂three in one＂ namely ore source layerstructure-magmatite ore forming geological condition. The area is very prospective for ores prospecting, and expected to become a middle to large pattern exploration base.
