以吉林和山东地区大型、超大型金矿为例 ,从运动学和动力学角度 ,系统研究其成矿作用的起点 (岩石—岩浆—流体间的物理化学作用 )和终点 (矿富集于断裂复合处或交汇部位 ) ,以及成矿流体在运动中的渗透、振荡、气—液态交替、流速的突变及多层次循环流体的萃取、沟通等多方面的共同作用。结果表明 ,巨量金质来源和富集的关键取决于各层次流体循环系统间的沟通 ,地幔富 C-H-O流体循环系统、中—下部地壳富硅流体循环系统、浅—表部 (主体位于浅部地壳和主体位于海底 )富硫流体循环系统3个层次的流体相互沟通、混合 ,导致流体循环持续时间增长 ,萃取围岩有用元素增多 ,成矿元素丰度升高 ,并最终形成金矿集中区。
Taking the large and very large gold mines in Jilin and Shandong as an example, the starting point of mineralization (the physicochemical interaction between rock and magma-fluid) and the end point Complex or intersection), as well as the interaction of ore-forming fluid during movement, oscillation, gas-liquid alternation, abrupt change of velocity and multi-level circulating fluid extraction and communication. The results show that the key to the source and enrichment of massive gold depend on the communication between the fluid circulation systems at all levels, the circulation system of mantle-rich CHO fluid, the silicon-rich fluid circulation system in the middle and lower crust, the shallow- The crust and the main body are located at the seafloor). The three levels of fluid in the sulfur-rich fluid circulation system communicate and mix with each other, resulting in the increase of the fluid circulation duration, the increase of useful elements in the extraction surrounding rock, and the increase of metallogenic element abundance, .
