东天山卡瓦布拉克地区低压麻粒岩地质温度计

摘要

据卡瓦布拉克地区环状熔融岩系电子探针分析成果,运用薄片域相邻稳定共生平衡矿物组合原理及高级变质岩中矿物组合相系压力理论,对该区麻粒岩中二辉石、二长石矿物对的摩尔分数数据进行计算,取得二辉石平均温度为840℃,二长石矿物的平均温度为647℃,压力小于0.4 GP的科学数据.%EPMA was conducted on the samples from ring melting rock series of Kawabulake,calculated the mole fractions of pyroxene and feldspar from granulite, according to the principle of the adjacent and stable mineral combination in the area of thin section and the theory of phase pressure about mineral combination in metamorphic rock, acquired some scientific data in the end.
