摘要
胶西北红布金矿在焦家金矿田独具特色,它不同于一般意义上的构造蚀变岩型金矿,是发育在断裂带两侧花岗(闪长)质岩石中受密集节理裂隙带控制的细脉、网脉状金矿。构造解析表明红布金矿体主要形成于主断裂发生右行走滑的构造应力环境,其主压应力方位大致为SWW－NEE,主压应力轴近水平,含矿裂隙表现为张剪性质。
Honghu gold deposit, a special deposit type different from structure - controlled alteration rock type gold deposit, is a veinlet - netted veingold deposit which is controlled by joint fissure zone and occurred near main fault in granitoid rocks. According to results of structure analysis, Hongbugold deposit was formed in such structure stress setting that main fault took placed right - lateral sliding, that the main pressure stress direction was SWW- NEE, and that main pressure axis was near horizontal. The mineralizing fissure expressed tenso - shear structure.
