| 摘 要： | 经过岩石学、热力学及熔体结构等方面的详细研究。笔者认为黄山杂岩体第二侵入体的3个岩相带是岩浆液态不混溶作用的结果。3个岩相带(橄榄岩相、二辉岩相、辉长岩相)分别由相应的3种岩浆形成,岩相内部的岩性变化则是分离结晶作用的结果。该文仅从岩石学角度对上述观点进行论证。

| Abstract: | On the basis of detailed reserch on petroilogy, thermodynamics and structure ofmelts, thethree lithofacies of the second stage of Huangshan complex arc considered as theresult of immiscibility of magma.The three lithofacies: olivinfels, Pyroxenolite and gabbrowere formed by threerelevent magma. The changes of lithological characters in everylithofacies were controlled by fractional crystallization.This paper demonstates the abovementioned points of view only on the basis of petrological study. |
