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.
