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.

The results indicated that the zircon phase is the major phase for the as-gained waste forms although containing 20mol% Eu3+. The alteration of 10-5~10-4 nm magnitude in the crystal cell parameters was measured (cf the standard XRD card of zircon). The equilibrium concentration of Eu3+ in HCI lixivium (pH=6.5) is less than 0.4μg/L.

The original Seluohe Group contains at least four parts: Late Archean metamorphic rocks (zircon SHRIMP protolith ages 2517~2534 Ma), Late Paleozoic metamorphosed volcanic-sedimentary strata (zircon SHRIMP 252 Ma), Permian gneissic granitic complex (zircon SHRIMP 260 Ma), and Jurassic mylonitized granites (zircon SHRIMP 168 Ma).

The zircon was dated by using the technique of single-zircon stepwise evaporation-deposition with a thermal ion mass spectrometry (Bernd Kober, 1986 and 1987). The zircon ages are 2.60-2.54 Ga for biotite-leptynite, 3.36-2.62 for mimatized leptite, and 3.53-3.08 Ga for quartzite from the iron formation.

The feldspars of topaz-lepidolite granite in Yashan late stage are P-rich albite and Kfeldspar, and the phosphorus goes into feldspar structure in the form of PAlSi〓 substitution. The phosphorus contents of feldspars vary according to their crystal habitus. In general, the feldspars of later generation have the higher average phosphorus content than that of earlier generation, and the albite contains higher phosphorus than the K-feldspar in the same generation. The zircon is highly rich in Hf, U, P and Al. The phosphorus enters the zircon structure mainly by the form of〓P〓〓Si〓, Al〓P〓Si〓 or P〓Al〓Si〓, Zr〓 substitution. The P-rich zircon is the production of the highly evolved magma, and it might be one of the important characteristic minerals of the high-P subtype granite. The manganocolumbite, manganotantalite, wodginite and titanowodginite are the main niobium and tantalum minerals.
