辽宁红透山太古宙块状硫化物型铜-锌矿床经历过高角闪岩相变质作用。矿石结构研究表明,矿床中的磁黄铁矿主要是海底喷流沉积后受到变质退火和重结晶的产物。在进变质过程中形成的磁黄铁矿的变形结构绝大部分已被峰期变质作用所清除,目前所见到的变形结构和矿石糜棱岩主要是退变质阶段的产物。流体的存在促进了磁黄铁矿的变形和退火。退变质流体以较高的氧逸度为特征。
The Archean block polymetallic sulphide copper-zinc deposit in Liaoning Hongtoushan experienced over amphibolite facies metamorphism. Ore structure studies show that the pyrrhotite in the deposit is mainly the product of metamorphic annealing and recrystallization after submarine jet deposition. The deformation structure of pyrrhotite formed in the process of metamorphism has been largely eliminated by the peak metamorphism. The deformation structure and ore mylonite currently seen are mainly the product of metamorphism. The presence of fluid promotes the deformation and annealing of pyrrhotite. Degenerated fluids are characterized by higher oxygen fugacity.
