摘要
含ＰＧＥ黑色岩系可根据黑色岩系中有无火成岩，将其分为：①与火山作用或岩浆活动无关的黑色岩系；②与火山作用或岩浆活动有关的黑色岩系。不同地质背景下，富金属黑色岩系的特征及其ＰＧＥ的分布特征既有相似之处，又各具特点，反映出两者ＰＧＥ的地球化学演化过程有所差别。有关ＰＧＥ比值不仅可以反映出元素的地球化学行为，亦可区分或指示不同环境下ＰＧＥ地球化学演化的规律性。
On basis of geological features, PGE-bearing black rock series can be divided into two types, (1) no relationship to volcanic action or magmatism; (2) relationship to volcanic action or magmatism.Under the conditions of variant geological underground, there are some similar features of geological PGE distribution, but there are also some differences.PGE ratios can not only show the geochemistry action of platinum-group element, but also explain the geological evolution rules of PGE in different environment.
