同位成矿概论

An Introduction to the Isospatial Metallogenesis

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。

The isospatial metallogenesis would be defined as follows:within the same particular location,during a certain peried or a-mong different periods,the same type of deposits or different types of deposits relatively stable multi-stage superposed mineralize。The paper consists of four parts:(1)based on the isospatial metallogenesis, the ore-forming mechanism of large-super-large de-posoits has been explained;(2)the marginal conditions of the isospatial metallogenesis,these conditions are favourable to the form-ing of large-superlarge deposits;(3)the characteristics of the isospatial metallogenesis;(4)the classification of the isospatial metal-logenesis.Finally,the relation of the isospatial metallogenenesis to the mantle plume is discussed。
