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.

According to the experimental results of Watson (1978), and Ryerson and Hess (1980), pertaining to the distribution of trace elements between basic and acidic liquids in the temperature above magmatic liquidus, and the investigation of Webster (1997) on the melt inclusion in pegmatitic quartz from Ehrenfriedersdorf ore district, Germany, it should be drawn that there probably exists the liquid immiscibility in the early stage of pegmatitic evolution, due to the perphosphorus content in the magmatic systems. The perphosphorus feature of the melt is of great impact on the petrogenesis and matellogenesis of pegmatites.
