鈉長石化

Secondary feldspar was related to the albitization process of feldspar, the albitization of plagioclase began at the early stage of diagenesis, and the albi. 次生長石與長石的鈉長石化過程有關(guān),斜長石鈉長石化始于成巖早期,而鉀長石的鈉長石化則需較高的成巖條件才能進(jìn)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. 長石的鈉長石化作用和長石、巖屑的水化水解作用、溶解作用,導(dǎo)致了不穩(wěn)定組分的轉(zhuǎn)變以及大量離子游離于孔隙水中,同時導(dǎo)致大量的自生礦物沉淀。

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，斜長石的鈉長石化可見于成巖早期，而鉀長石的鈉長石化只發(fā)生于成巖晚期。

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. 產(chǎn)于太古宇建平群小塔子溝組片麻巖中,受生金皋斷裂控制,礦體和礦化體產(chǎn)于近SN向斷裂內(nèi),與礦化有關(guān)的熱液蝕變有絹云母化、硅化、黃鐵礦化、鈉長石化等。
