变质岩

2The studies on the appearance typomorphism, physical typomorphism, inner structure typomorphism and chemical typomorphism of the zircon and garnet, and the result of U-Pb isotopic age dating of zircon indicate that the zircons are meta-morphogenic genesis but two or three of them are magmatic genesis and most meta-morphogenic zircons have a basic magmatic zircon core which was generated in Stage of Yanshand and Indo-Chinese epoch. The genesis and origin of the garnet is very complicated. The garnets are main almandine with high Fe and Mg content and were proposed their souce rocks are mostly regional mid-degree-metamorphic rocks.

2研究锆石和石榴石的形貌标型、物性标型、内部结构标型以及成分标型特征和锆石U-Pb同位素测年结果表明，锆石除少数几个为岩浆锆石外，绝大多数是变质锆石，且中间多有形成于燕山-印支期的基性岩岩浆锆石残核；石榴石的成因及来源是比较复杂的，以铁铝榴石为主，且铁铝榴石中Fe、Mg的含量较高，推测其源区母岩主要以中级区域变质岩为主。
