| 摘 要： | 本文简要讨论了花岗岩中常用压力计的应用限制条件和误差.对于钙碱性花岗岩推荐使用角闪石全铝压力计；对低压矿化岩体建议使用黑云母全铝压力计即可；奥长环斑花岗岩中可应用富铁斜方辉石-铁橄榄石-石英组合压力计；存在两种长石和石英平衡共结的花岗岩可利用Q-Ab-Or-H2O相图获得它们的共结压力.花岗岩矿物中流体包裹体的内压可以... |

| Abstract: | This paper briefly and critically discusses several common geobarometers applied to granitic systems,especially the specific rock types,and their limitation and error analysis.The Al-in-hornblende barometer can be applied to calc-alkaline granites and is suitable for low-pressure mineralized granitic pluton.The Fe-rich orthopyroxene-fayalite-quartz assemblage barometer can be used to calculate the crystallization pressure condition of rapakivi granites,and the crystallization pressure of coexisting alkali f... |
