兴城台里地区含石榴子石结晶岩系的成因和特征

The causes and characteristics of crystalline rock series containing garnet in Taili,Xingcheng

兴城台里地区主要出露经过变质作用的结晶岩系,前人主要对该地区结晶岩脉侵入的新老关系做了研究,但对于含石榴子石结晶岩的形成和特征没有严格的阐述与定论,作者通过对辽宁兴城台里地区含石榴子石的结晶岩系地区进行实测填图、野外采样、标本分析和薄片观察等研究工作,来研究该地区含石榴子石的结晶岩系的成因和特征。结合相关资料综合分析,得出该地区含石榴子石的结晶岩系为早期侵入的花岗细晶岩通过岩浆期后局部变质的结论,石榴子石的规则排列是由于残浆溢出时冷凝和交代作用形成的,同时验证了该地区石榴子石的主要类型为红色的镁铝榴石的结论。

The author through the study of the measured mapping, field sampling, The specimen analysis, thin section observation on Taili Xingcheng Liaoning which has the garnet crystalline rock series. To research the garnet crystalline rock series, causes and characteristics of garnet. Comprehensive analysis combined with related information, come to the conclusion that the garnet crystalline rock series are the early invasion of aplite granite by regional metamorphism magmatic period, the regular array of garnet residual come from the magmatic condensation when overflow and metasomatism. And it is verified that the main types of garnet is red pyrope.
