摘要
通过对邯邢地区燕山期角闪闪长岩系岩石的岩相学、岩石化学和矿物化学的研究,认为岩浆的演化机制是矿物分离结晶作用,以角闪石为主的矿物分离结晶是影响岩浆成分变异的主导因素。
The data of petrography, petrochemistry and mineral chemistry of the rocks from Hb-diorite series in Han-Xing district indicate that the evolutionary mechanism of the magma is the mineral fractional crystallization. The hornblende-dominated fractional crystallization is mainly responsible for the changes of the composition of the magma during the magmatic evolution.
