云英岩化

个旧矿区的热液活动及热液蚀变作用很突出，花岗岩中的热液蚀变有：碳酸盐化、绿泥石化、云英岩化、绢云母化、钠长石化。

Hydrothermal alterations in granitic rocks include carbonatization , chloritization , greisenization , sericitization and albitization .

矿区围岩蚀变强烈，与成矿较为密切的主要有云英岩化、矽卡岩化、硅化和碳酸盐化。

Wallrock alteration of mining area is strong , including greisenization , skarnization , silicification and carbonatization , which are closely related to mineralization .

断裂构造、云英岩化与成矿关系密切，花岗岩应是成矿母岩。

Fracture , Yunying paleokarstification is related closely to mineralization , granite should be mineralization source rocks .

围岩蚀变发育，类型多样，其中云英岩化、黄玉化、萤石化和褐铁矿化是重要的找矿标志。

Greisen-lithify , topaz-lithify , fluorite-lithify , and limonite-lithify are important mark in seeking mine with alteration wall rock development and type variety .

燕山构造旋回控制的晚期岩浆，随着构造演化产生云英岩化、石榴子石化等岩浆自交代而锡铌钽矿物结晶富集成矿；

The Yanshanian magmas in late phases , gave rise to sericitization and garnetization , and then Sn , Nb and Ta were enriched due to magmatic-authometasomatism .

这种类型的矿床由许多的锡、钨矿化脉（包括石英一云英岩脉，云英岩脉、硫化物石英脉、云英岩化长石脉等）和石英&白云母云英岩化的矿化花岗岩所组成。

This type of deposit consists of many mineralized veins of tin and tungstun which include quartz-greisen , greisen , sulfide-quartz , greisenization feldspar erc and mineralized granite of quartz-muscovite greisenization .
