As a result, if the iridescence is produced by thin-film interference, not only the thickness of lamellar structure must be defined within a certain nanometer, but also the refractive index need to be different between lamellar structure. In other words, the chemical composition, refractive index and thickness of exsolution lamellae need form to trinity, such as labradorite, albite, andradite and orthoamphibole. If the iridescent color is produced by grating-diffraction, the lamellar structure just needs to be arrayed regularly, the spacing of the edges of lamellar structure needs to be regular and narrow, but not necessarily within the range of the wavelength of visible light, such as shell of abalone, pearl and opal.

薄膜干涉式晕彩不仅要求宝石内部结构层的厚度必须在一定的纳米范围内，而且结构层内部的折射率也必须有所差别，也即，当结构层由两相组分出溶而成，其化学成分、折射率和结构层厚度形成三位一体时，符合薄膜干涉式晕彩，如拉长石、钠长石、石榴石和角闪石；而光栅式衍射晕彩则仅要求结构层排列规则，边缘狭窄但不需要窄到可见光波长范围内，能使入射光的振幅或位相，或两者同时产生周期性空间调制的结构即可，如鲍贝壳、珍珠和欧泊。

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.

According to the phase relationship in the reaction system felsic melt＋ small amount of peridotite, we suggest that assimilation of the mantle clinopyroxene ＋ olivine ＋ spinel as well as the fractional crystallization of sodic amphibole and clinopyroxene is an important process which modifies the composition of adakites and cause the Na depletion in adakites..
