The average contents of phosphrus in alkali feldspars in both comb zone and the first intermediate zone are high, in the range of 0.42-0.22wt%, and gradually increase from 0.21wt% to 0.50wt% as the magma evolves from the third intermediate zone to the core zone. The abnormally low content of phosphrus (＜0.10wt%) in alkali feldspar from the saccharoidal albite zone is considered due to the crystallization of apatites, which gives rise to extreme depletion of phosphrus in residual melt.

阿尔泰3号伟晶岩脉梳状结构带和Ⅰ带的碱性长石具较高P含量(平均值分别为0.42wt％和0.22wt％)，随着岩浆的演化进行，从Ⅲ带到核部带，碱性长石中P含量逐渐增大(平均值由0.21wt％增至0.50wt％)，而Ⅱ带碱性长石中异常低的P含量(平均值为0.08wt％)是该带大量磷灰石矿物饱和结晶，导致残余熔体相中P极度亏损所造成的，而不是晚期出溶的岩浆热液交代形成的。

The feldspars from the γA1 and γAIIa show many clear metasomatic alteration features; the- refore, the authors genetically consider the albitized protolithionite granite and the albitized zinnwaldite granite to be metasomatic altered granites.

花岗岩中长石具有清楚的交代特征，晚期岩体中的钾长石的An和Ab组份十分低，斜长石中的An和OI组份也很低，说明钠长石化黑鳞云母花岗岩和钠长石化铁锂云母花岗岩为交代蚀变花岗岩。

本文通过对刘家洼杂岩体角闪石、长石矿物化学的研究，揭示岩体形成时的温度为 73 0～ 81 0℃，而结晶压力变化于 6.6× 1 0 8～ 2 。2× 1 0 8Pa之间，表明在该岩体形成过程中，经历了明显的剥露作用。

The low homogenization temperatures indicate that the petroleum is encapsulated at the cooling stage of the diabases that have intruded in the Es3 strata when the interaction between ground water and the feldspars resulted in alteration.

测得其中部分粒径较大的石油包裹体的均一温度 th=79～ 82 ℃，表明这些石油包裹体是辉绿岩体侵入 Es3地层冷却以后受地层水作用在发生的多种蚀变反应的过程中长石的节理、裂隙愈合带封存了渗入的烃类物质而形成的。
