In the high-grade metamorphism and anatexis process, in which sapphirine was formed, the multistage crystallization of minerals resulted in the complexity of the mineral association, such as the differentiation of leuco-and melano-components. Generally, the mafic-rich minerals formed earlier, and the differentiation of magnesio-and iron-components is responsible for the earlier presence of ironrich minerals, i.e., magnesio-rich minerals crystallized later, thus the successive associations of multistage occurred.

在形成假蓝宝石的高级变质-深熔作用过程中，岩石矿物组合的变化主要是多阶段变质造成的，如浅-暗色组分发生了分离，其中含镁铁组分多的矿物较早结晶，而镁铁组分的分离使得相对富Fe的矿物较早结晶，即晚期形成的镁铁质矿物更富Mg组分，并形成递进演化的不同阶段的组合。

The author creates the AutomaticallyDiscriminational Model for the Classification of Sandstones System, thatis to say, people can complete the vastly sample s classification of sandstonesaccurately and swiftly, meantime, diminish the possibility of mortal mistake. Based on the study of the basic sandstone component before embedding, the typeof authigenic mineral, and the forming mechanism of porosity in Upper Paleozoicreservoirs in Ordos basin, the author selects the reasonable experiment objects forWater-Rock Interaction modeling study, designs the relatively reactant and resultantduring the diagenesis period, builds the solid-liquid thermodynamics model with theprinciple of thermodynamic phase equilibrium for kinds of primary minerals (potashfeldspar, albite, anorthite, and pyroxene, hornblende) which dissolve in acidic media,and forms the corresponding thermodynamics test database.

在对鄂尔多斯盆地上古生界储层砂岩埋藏前组成、自生矿物类型和孔隙构成研究的基础之上，确定合理的沉积盆地水—岩相互作用模拟研究的实验对象，设计了埋藏成岩过程有关反应的反应物和可能的生成物，并通过热力学相平衡原理，建立了碎屑岩在埋藏成岩过程中各种骨架颗粒(钾长石、钠长石、钙长石以及铁镁暗色矿物中的辉石、角闪石等)在酸性介质条件下发生溶解的固体—流体相化学反应热力学计算模型，并获得了相应的热力学数据库，在此基础上对储层砂岩中主要造岩矿物(钾长石、钠长石、钙长石以及铁镁暗色矿物中的辉石、角闪石等)在埋藏成岩过程的酸性介质条件下发生溶解的热力学习性进行了论述。

As a result, the author discusses the thermodynamics habitus for the minerals either. With the calculation of the thermodynamics modeling, we run the dissolutionmodeling experiments for primary minerals (potash feldspar, albite, anorthite, andpyroxene, hornblende), which is under the conditions of organic acidic and 20 varietytemperature and pressure. The dissolution modeling experiments include 4 anorthitedissolution experiments, 8 pyroxene dissolution experiments, 8 hornblendedissolution experiments. We catch the records on the X ray diffraction, chemistryanalysis, SEMphotos, and the PH parameters. By theway, we discuss the dissolution habitus for the minerals either.

在热力学模拟计算的基础之上，进行20个不同温度和压力条件下，以有机酸作为溶解介质的储层砂岩骨架颗粒(钾长石、钠长石、钙长石以及铁镁暗色矿物中的辉石、角闪石等)的水—岩相互作用的溶解模拟实验，包括：4个钙长石的溶解实验、8个辉石的溶解实验和8个角闪石的溶解实验，获得了溶解模拟实验前后全部参与实验矿物的X射线衍射分析、化学全分析数据、扫描电镜照片，以及介质流体在实验过程中化学参数pH值的检测，在此基础上讨论了铁镁暗色矿物、长石等铝硅酸盐矿物在埋藏成岩过程中酸性介质条件下的溶解习性。

Calculation on phase equilibria in the KFMASH and NCKFMASH systems indicates that the phase relations of ferromagnesian minerals are controlled by the KFMASH.

在模拟泥质岩石的KFMASH体系和NCKFMASH体系中的相平衡计算表明，NCKFMASH体系中铁镁矿物的相平衡关系受KFMASH亚体系中矿物相平衡关系的控制，但KFMASH亚体系中固相线位置要比实际的高50-60℃。

It is found that there is a mineral association, micro-crystal muscovite and phengite, in this deposit. The mineral assemblage contains about 80% micro-crystal muscovite and about 20% phengite. Their crystallinity is very high and their polytype is 2M1. Both of them are dioctahedral because the d and b of micro-crystal muscovite and phengite are 0.1502 nm, 0.9012 nm and 0.1505 nm, 0.9030 nm, respectively. For their d and b are larger than those of common muscovite, the reason why Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+) are high in the ore is that Al(superscript 3+) in the octahedron is replaced by Fe(superscript 2+)+Fe(superscript 3+) and Mg(superscript 2+), and this is a phengite series mineral association formed through isomorphic replacement.

该矿物组合中的微晶白云母和多硅白云母结晶度高，多型为2M1，其含量分别为80%和20%左右；二者都属二八面体型白云母类矿物，但d060和b值偏大，微晶白云母的d060=0.1502nm，b=0.9012nm，多硅白云母的d060=0.1505nm，b=0.9030nm；微晶白云母矿铝含量较低、铁镁含量较高，其原因是白云母晶体铝氧八面体中的Al离子被Fe、Mg等离子所取代，这一矿物组合是通过矿物类质同象作用所形成一种多硅白云母系列矿物。

The rework of peak composition in core of garnet far away from biotite and other Mafic minerals is much slighter than those surrounded by biotite.
