摘要
辽宁抚顺"红透山式"铜矿产在浑北太古宙绿岩带内,宏观上受控于太古宙红透山岩组绿岩建造.红透山铜矿所处的浑北太古宙绿岩区,活动历史漫长,演化过程复杂,经受太古宙3幕韧性变形过程,形成多样式变形形迹组合.鞍山期韧性变形阶段的多期褶皱及其相伴形成的韧性断层对红透山式铜矿具有控、容矿作用.红透山式铜矿受构造的叠加、改造和控制特征明显,其构造控矿属性可以作为重要的找矿标志。
The ＂Hongtoushan type＂ of copper deposits in Fushun, Liaoning Province, occurred in Hunbei Archean greenstone belt, is macroscopically controlled by the Hongtoushan greenstone formation. The Hunbei Archean greenstone belt is characterized by long period of movement and complex evolution, with three episodes of ductile deformation and varied assemblages of deformation. The multistage folds and accompanying ductile shear faults, which formed in Anshan ductile deformation phase, are significant control and hosts for the ＂Hongtoushan type＂ of copper deposits. The structural control to the copper deposits is so obvious that it can be regarded as an important ore guide for such type of deposits.
