同位成矿是指在同一空间范围内，同时代与不同时代，同矿种与不同矿种，同类型与不同类型相对稳定的成矿作用及其成矿规律的总称。提出了同位成矿是大型—超大型金属矿床（矿田）形成的宏观机制；讨论了同位成矿的边界条件，只有在边界条件以内才有可能形成大矿；阐述了同位成矿的某些特点；划分了同位成矿的类型。并指出同位成矿可能与幔流柱活动密切相关。
Isotope mineralization is the general term for the metallogenic process and its metallogenic regularity that are relatively stable in the same space, contemporaries and different ages, with the same type and with different types of minerals. It is proposed that isotopic mineralization is a macroscopic mechanism for the formation of large-super-large metal deposits (ore fields). The boundary conditions of isotopic mineralization are discussed. It is possible to form large mines only within the boundary conditions. Some of the isotopic mineralization Characteristics; Divided into the type of ore-forming. It is pointed out that isotopic mineralization may be closely related to mantle flow column activity.
