greisenization

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

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。

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

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。

Research indicates that the main ore-controlling factors are intrusion of granitic magma , multiple activities of regional faults and greisenization .

研究认为花岗岩浆的侵位、区域性断裂的多次脉动作用及蚀变作用是区内钨锡矿形成的重要控制因素。

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 .

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。
