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.

雅山晚阶段黄玉锂云母花岗岩的长石矿物是富磷长石，磷以PAlSi〓替换方式进入长石结构中，并且在长石中的分布很不均一，一般是晚结晶的长石比早结晶的长石的磷含量高，同期结晶的钠长石比钾长石的磷含量高；锆石矿物为高度富铪、铀、磷和铝的锆石，磷主要以(Y， HREE， Fe)〓P〓〓〓Si〓〓、Al〓P〓Si〓〓、P〓Al〓Si〓〓Zr〓〓等替换方式进入锆石晶格中，富磷锆石是岩浆高度演化的结果，是高磷花岗岩的特征矿物之一；雅山含有丰富的磷锂铝石，是高磷花岗岩的主要磷酸盐矿物；铌—钽矿物主要有铌锰矿—钽锰矿、锡锰钽矿—钛锰钽矿、细晶石等。

Bassed on many kinds of characteristics of the alkaligranite, the paper establishes a complex genetic model of A-type granite in wulungu alkali-granite, that is" activity of mantal material+partial melting of hydrous-absent saclic source rock+differentiation of granitoid magma+tensional geological envioment".

Meanwhile the SHRIMP zircon U-Pb age of the fine-grained monzonitic granite is (131.4±1.6) Ma. These precise dating results represent the ore-forming period of this molybdenum deposit, the main dominant geological events and suggest its close relationship with buried Yanshan fine-grained monzonitic granite.

文章通过采集WZK1钻孔211.2~214 m细脉浸染状矿石的辉钼矿纯样，获得辉钼矿的等时线年龄为(134.1±3.3) Ma，并对比了矿区细粒二长花岗岩的锆石SHRIMP年龄(131.4±1.6) Ma，两者基本一致，表明矿床的形成主要与隐伏的燕山期细粒二长花岗岩有着密切关系。
