太行山北段金矿研究表明,金的成矿物质主要来自深源,部分萃取自迁移途中的围岩。成矿具有明显的成矿集中期和集中区,这种时间、空间分布特征与地幔热柱多级演化密切相关。含金的深源流体随地幔热柱多级演化向上迁移,当其迁移到幔枝(变质核杂岩)外围主拆离滑脱带及其上盘裂隙扩容带时,由于物理、化学条件的改变,使其聚集沉淀成矿,并可表现出斑岩脉型、隐爆角砾岩型、大脉型、网脉型等多种矿石类型为一体的系列成矿。硫、铅、氢、氧等同位素测定值亦表明含金流体主要来自深源,其上升过程中有部分壳源流体和大气降水混入,因此,构造变形是成矿控矿的主导因素。本文还进一步探讨了构造成矿控矿作用,归纳出了成矿模式。
Gold deposits in the northern part of the Taihang Mountains show that the metallogenic materials of gold are mainly derived from deep sources and partly from the surrounding rock during migration. Mineralization has obvious concentration of mineralization and focus area, the temporal and spatial distribution characteristics of the mantle plume is closely related to the multi-level evolution. Gold-bearing deep-source fluids migrate up the multistage evolution of the mantle plume and migrate upward into the main detachment stripping zone and its upper plate fracture expansion zone at the periphery of the mantle branch (metamorphic core complex). Due to changes in physical and chemical conditions , Making it accumulate precipitation mineralization, and can show a variety of ore types of porphyry veins, cryptoexplosive breccia type, vein type, network pulse type as a whole series of mineralization. Sulfur, lead, hydrogen, oxygen and other isotope measurements also showed that the gold-bearing fluid mainly from the deep source, the rising process of some of the crustal source fluid and the precipitation mixed with precipitation, therefore, tectonic deformation is the dominant factor of ore-forming ore. This article further explores the role of tectonic ore-controlling and summarizes the metallogenic model.
