文摘 综述了当前对基性-超基性岩床和层状岩体的边缘反转现象的传统解释模型,包括围岩混染、岩浆多期注入、岩浆分层、过冷却、晶体沉降、流动分异、结晶和成分对流以及逐渐减少的颗粒间熔体量。详细论述了这些模型的优缺点,认为Soret效应是目前对边缘反转现象比较合适的解释,讨论了中国峨眉山大火成岩省朱布岩体的Soret成矿现象。
其他语种文摘 This paper reviews the conventional models for the formation of marginal compositional reversals,including wall-rock contamination,multiple injection,compositional stratification of magma,high degree of supercooling,crystal settling of phenocrysts,flow differentiation,compositional convection and upward decrease in amount of intercumulus liquid.All these models have shortcomings to explain the marginal compositional reversals,so the current proper model for the marginal compositional reversals is Soret effect,although it is controversial in petrogenesis of the marginal reversals.The success in explaining the petrogenesis and metallogenesis of the Zhubu intrusion provided additional evidence for the Soret effect in petrology.
