摘要
石榴石是山西岚县袁家村一带 -娄烦县出露的吕梁群地层中主要的特征变质矿物 ,其次为黑云母、十字石等 ,对这些特征变质矿物进行电子探针的成分分析及其相关计算 ,并利用不同采样点的矿物对估算该点变质温度和压力 ,最后得到石榴石的成分变化与变质程度之间的关系 。
Garnets are widely distributed through the layers in Lan county of Shanxi province,the electronic probe analysis shows that garnets in different spots have different composition,even in different zone of the same grain,with the estimated calculation of temperature and pressure based on the mineral assemblages,we come to conclusion that composition of garnet is related to the degree of metamorphism and further gives indications of the condition of metamorphism.
