The first stage was mixing of gabbroic and granitic magmas, which formed dioritic rock;
第一期为辉长质与花岗质岩浆混合，并生成闪长质岩石；

In the Cathodoluminescence (cl) images the zircons extracted from the dioritic gneiss show good crystal morphology and clear oscillatory zoning, as is the case of magmatic zircon.
在阴极发光图像中，片麻岩中的锆石具有较好的晶形，并显示出清晰的岩浆锆石韵律环带结构。
