摘    要:利国矿区是江苏省重要铁矿基地之一,矿区位于秦岭一昆仑纬向构造带东延的南侧与新华夏构造体系第三隆起带的交接复合部位。铁矿床主要产于燕山期闪长玢岩杂岩体与下奥陶统碳酸盐地层的接触带及其附近灰岩中,矿体呈似层状一透镜状等,产状与围岩一致,具层控矿床的特征。笔者主要从成矿地质特征着手,分析总结了该区铜、金矿化特征及主要成矿规律,指出了利国矿区铜(金)矿的找矿方向和有望靶区。

关 键 词:铜(金)矿  成矿条件  找矿方向  利国  江苏

Abstract:The Liguo mining area, one of the important mining bases for iron deposits in Jiangsu Province, locates in the junction of southern side of east-extending Qinling-Kunlun latitudinal structural zone and the third uplift belt belonging to Neocathysian tectonic system. Most orebodies of the iron deposit occurred in the contacting zone between Yanshanian dioritic porphyrite complex and Lower Ordovician carbonate strata as well as limestones near the aforesaid contacting zone. The orebodies in quasi-lamellar lens-like shapes occurred parallely with the wall rocks, and presented some characters of strata-bound deposit. According to the geological characteristics of the studying area, the author has analyzed and concluded Cu, Au mineralization characteristics and major ore-forming rules of this area, as well as pointed out the prospecting direction and hopeful target areas for Cu (Au) deposits in Liguo mining area.
Keywords:Cu (Au) deposit   ore-forming conditions   prospecting direction   Liguo   Jiangsu
