MEp which crystallized earlier than biotite or hornblende in the magma, can not be used as a barometer, but be useful in caculating the ascent speed of magma.
作为早期结晶的矿物,绿帘石不能作为压力计来反映岩体侵位深度,因为在绿帘石晶出时,岩浆中液相体积在50%~80%,这样岩浆可能会有快速侵位的过程,但它的地质意义在于能够对岩浆上升速率做出估算。

The first method is not related to petrogenesis, but welcomed by its benefit in field work and basic petrology research; the second method reflects magma sources and tectonic environment, which has always been considered to be very important since proposed, especially a steady flow of A-type granite result in recent years; the third method, often used by researchers, consists of information about mineralogy, petology and magma source; the last method is characterized for its simple and uniform classification criterion, as well as strong operability.
矿物学-岩石学分类不涉及成因信息,比较适用于野外工作以及最基本的岩石学研究;ISMA分类的标准反映的是岩浆源区和构造环境,自提出后备受重视,尤其是A型花岗岩的研究成果近来大量涌现;Barbarin的综合性分类包含了矿物学、岩石学和岩浆源区的信息,也受到一定的推崇;Frost的地球化学分类标准统一,具有很强的操作性。

The sinking rate of the spherical heavy solid in static liquid is in accord with Stocks formula.The plutonic inclusions in igneous rocks which formed as a result of solidification of magma have the same relation as magma.
静态流体中的球形固体重物的沉降速度服从Stocks公式,岩浆岩是由岩浆上升冷凝而成,在形成时与其中的深源包体也是这种关系,只是包体没有沉下去,反而随岩浆上升,说明岩浆上升速度大于最重最大包体的下沉速度,据此可确定该岩浆岩形成时岩浆流体上升的最小速度并推导出计算公式。
