albitization

钠长石化

Secondary feldspar was related to the albitization process of feldspar, the albitization of plagioclase began at the early stage of diagenesis, and the albi. 次生长石与长石的钠长石化过程有关,斜长石钠长石化始于成岩早期,而钾长石的钠长石化则需较高的成岩条件才能进行。

The hydration-hydrolysis and dissolution rock fragments and feldspar and albitization of feldspar make many ions free from their framework and go into pore-water. 长石的钠长石化作用和长石、岩屑的水化水解作用、溶解作用,导致了不稳定组分的转变以及大量离子游离于孔隙水中,同时导致大量的自生矿物沉淀。

Therefore, the albitization of plagioclase is shown in the early stage of diagenesis and albitization of potash feldspar appears only in the late stage of diagenesis. 因此，斜长石的钠长石化可见于成岩早期，而钾长石的钠长石化只发生于成岩晚期。

The ore body and the mineralization occurs in the SN-trending fault.The hydrothermal alterations related to the mineralization are sericitization,silicification,pyritization and albitization. 产于太古宇建平群小塔子沟组片麻岩中,受生金皋断裂控制,矿体和矿化体产于近SN向断裂内,与矿化有关的热液蚀变有绢云母化、硅化、黄铁矿化、钠长石化等。
