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.

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.

On the basis of petrography and mineral chemistry of the xenoliths, the amphiboles in them can be subdivided into four kinds of occurrences ,i.e., 1 the early amphibole inclusions within garnet, being maganesio-hornblende; 2 the primary amphiboles equilibrated with omphacite and garnet in eclogite, belonging to pargasite and pargasitic hornblende; 3 the retrograde amphiboles around garnet and clinopyroxene, mainly being edenitic and actinolitic hornblendes; and 4 the exsolving amphiboles within clinopyroxenes, mainly being edenite, edenitic hornblende and/or ferroan pargasitic hornblende.

对该类捕虏体的岩相学和矿物化学研究表明，其中的角闪石具有4种产状：1位于石榴石中的早期角闪石包裹体，为镁质普通角闪石；2与榴辉岩中矿物平衡存在的原生角闪石，为韭闪石或韭闪石质普通角闪石；3位于石榴石和单斜辉石周边的退变角闪石，主要为浅闪石质和阳起石质普通角闪石；4沿单斜辉石解理分布的出溶角闪石，主要为浅闪石、浅闪石质角闪石和含亚铁韭闪石质普通角闪石。

For the sample consisted of plagioclase, clinopyroxene and hornblende, rheological behaviors are controlled by plagioclase and clinopyroxene when the content of hornblende is less than 10%, however, the role of hornblende could become significant for deformation of samples when the content of hornblende is higher than 10%.

由斜长石、单斜辉石和角闪石组成的样品中，当斜长石和单斜辉石含量接近，而角闪石含量低于10％，斜长石和单斜辉石控制了岩石的流变；如果样品中有超过10％的角闪石参与流变，角闪石在变形中所起作用非常显著。

For the sample with major mineral of plagioclase, quartz and hornblende, rheological behaviors are dependent on plagioclase and hornblende when content of quartz is less than 10%, but when plagioclase content is near 70% it will decide the deformation behaviors of the samples. In contrast to that, quartz could completely control the creep of samples when its content is higher than 20%.

由斜长石、石英和角闪石组成的样品，当石英含量小于10％而斜长石和角闪石含量接近时，斜长石和角闪石控制了岩石的流变；当斜长石含量达到70％时，样品变形更接近长石特性；如果石英含量超过20％时，石英在变形中起到主要作用。

This paper also shows the distribution of the fluorine in sediments of the area is mainly controlled by the chemical composition of the material from the surrounding islands, and the element seems to be incorporated by the hornblende at the most extent, thus the correlation between the element and the hornblende amount in the sediments can be expressed statistically as following: F=217+lnVh.

研究结果表明，测区沉积物中氟含量分布主要受周围岛屿风化基岩的化学成分制约；沉积物中主要含氟矿物：萤石/磷灰石、黄玉、黑云母等含量极低，氟在沉积物中赋存的矿物相主要与角闪石[AX_2Y_5Z_8O_(22)_2]有关。氟含量与碎屑矿物中角闪石的体积比间的关系式可大致表示为：氟含量=217+361nV_H；间隙水中的低氟主要由测区化学风化不发育及氟的钙盐沉积所致。
