同位成矿作用系指在同一成矿空间内,循时间序列,伴随地质演化的进程,某种元素、元素组合的多期富集成矿、叠加和定位作用过程的总称。以铜多金属矿床为例,初步厘定了同位成矿作用的类型(异时单期同位成矿、异时多期同位成矿、同时多型同位成矿)、剖析了同位成矿作用的边界条件(丰富的成矿物质和成矿流体、稳定且长期活动的热中心及迁移通道、优化的成矿系统结构和局部适宜的沉积环境),并从理论上阐述了同位成矿作用与区域地幔成分的不均一性、地幔喷流柱的关系和同位成矿作用的机制
Orthomorphism refers to the general term of multi-period enrichment and mineralization, superimposition and localization of certain elements and elemental assemblages in the same metallogenic space, along time series and accompanying geological evolution. Taking the copper polymetallic deposit as an example, the types of isotopic metallogeny (heterogeneous single-stage isotopic mineralization, multi-stage isotopic mineralization at the same time and multi-type isotopic metallogeny) were initially determined, and the boundaries of isotopic mineralization were analyzed Conditions (abundant ore-forming materials and ore-forming fluids, stable and long-term thermal activity centers and migration channels, optimized metallogenic system structures and locally suitable depositional environments) and theoretically elucidated the relationship between isotopic mineralization and regional mantle The heterogeneity of the composition, the mantle-jet column and the mechanism of isotopic mineralization
