AndLeptochlorite in Goutouling mine, chamoisite in Bailashui mine and brunsvigite inWuchangping and Shanmenkou mines are concluded by Electron-probe analysis .The content ofFe is richer in this field, which demonstrates forming environment is relatively acid andFe/ of different stages of mineralization is regular.

对其电子探针分析表明，绿泥石的种类分别是狗头岭矿区的鳞绿泥石、白腊水矿区的鲕绿泥石、山门口和白腊水屋场坪矿区的铁镁绿泥石和辉绿泥石，说明芙蓉锡矿田中绿泥石都为富含铁的绿泥石，铁取代镁，铁含量增大，表征其形成于相对酸性环境，且不同成矿期Fe/有一定规律性。

According to geologic settings, distribution regularities of ore deposit and major metallogenesis in metallogenic belts, it was thought that typical deposits in metallogenic belt of North of Eastern Kunlun is Kendekeke SEDEX-hydrothermal diplogenetic Co, Bi, Au deposit and Baiganhu hypothermal W, Sn deposit, that in metallogenic belt Middle of Eastern Kunlun is Wulonggou orogenic gold deposit, that in metallogenic belt South of Eastern Kunlun is Tuolugou SEDEX Co deposit, and that in metallogenic belt of A'nyemaqen-Bayan Har is Dachang orogenic gold deposit.

The discriminant analyses,of 28 granitic intrusives distributed in the periphery of the stanniferous granite bodies,by using the Keluo-Lazi diagram,SiO2-Al2O3+Na2O+K2O-CaO+MgO+FeO diagram,Fe-Na+K-Mg diagram and K-Na-Ca diagram,,indicate that the four diagrams can be applied to...

对分布于含锡花岗岩类岩体外围的28个可能含锡岩体进行科勒-拉兹图解、S iO2-A l2O3+Na2O+K2O-CaO+MgO+FeO图解、Fe-Na+K-Mg图解和K-Na-Ca图解判别后发现，壳源酸性花岗岩类完全可以用四图解进行含锡性判别，并且完全符合实际地质特征，大部分都有希望找到伴生壳源型锡矿床；而幔源中基性花岗岩类的含锡性却不适用上述四个图解进行判别。
