| 摘 要： | 新疆诺尔特地区花岗岩分布广泛 ,主要为加里东晚期 ,华力西中、晚期及燕山期花岗岩。文章选取各期花岗岩中的主要岩体 ,应用斜长石粒度体视学方法研究了花岗质岩浆的演化。结果表明 ,区内花岗质岩浆的演化受对流分异作用控制。研究结果同时表明了斜长石粒度体视学在花岗质岩浆演化研究中的可行性

| Abstract: | The granites formed at late Caledonian stage,middle Hercynian stage,late Hercynian stage and Yanshanian stage are widely exposed in the Nurt region,Xinjiang. The typical granite bodies at each stage have been selected and the evolvement of granitic magma is studied by using the plagioclase crystal size stereologic method.The results show that the evolvement of granitic magma is controlled by the convective fractionation. The results also show that it is feasible to study the evolvement of granitic magma by using the plagioclase crystal size stereologic method. |
