成岩共生组合I由长石颗粒溶解、次生加大石英和自生高岭石组成，该组合形成于酸性成岩环境；成岩共生组合II由自生伊利石、自生钠长石、自生石英与高岭石溶解、白云石、铁白云石、铁方解石组成，该组合形成于碱性成岩环境；其次，露头砂岩还包括由长石颗粒溶解、高岭石、地开石、褐铁矿组成的第III种成岩共生组合，该组合形成于地表酸性成岩环境。

Anorthite and albite are important calcium-containing feldspars.

钙长石与钠长石是重要的含钙长石。

The anorthite component of plagioclase from Kela 2 reservoir was dissolved so completely by the pore fluid that the dissolution made great contribution to the pore volume, and the albite component suffered partially dissolution; by contrast K-feldspar did not dissolved in the ground water at all.

克拉2 气田中斜长石骨架颗粒中的钙长石组分基本上遭受了彻底的溶蚀，对次生孔隙的贡献较大，钠长石溶蚀程度有限，而钾长石基本上不被溶蚀。

Labradorite which is a plagioclase feldspar of the triclinic class is well known for the striking iridescence which it exhibits. What is the material which is responsible for the iridescence of labradorite and why is it present?

上世纪七、八十年代，拉长石的晕彩成因引起了人们的广泛关注，普遍认为拉长石的晕彩色并非因其晶体内部的杂质或包裹体所致，更可能是因拉长石内部的周期性层状结构对光的干涉作用所致。

Feldspar can be divided into two large group, the potassium feldspar includes orthoclase and microcline

长石可以分为钾长石和斜长石两大类，钾长石中包括正长石和微斜长石

Recently, the Gem Testing Laboratory of Jaipur from India has encountered three aventurine feldspar samples which have been primarily proved belonging to the potassium feldspar rather than the oligoclase.

最近，印度斋浦尔宝石检测实验室检测了3颗具砂金效应的长石样品，经过初步证实其可能属于钾长石而不是奥长石。

Secondary feldspar was related to the albitization process of feldspar, the albitization of plagioclase began at the early stage of diagenesis, and the albi.

次生长石与长石的钠长石化过程有关，斜长石钠长石化始于成岩早期，而钾长石的钠长石化则需较高的成岩条件才能进行。

The tectonic rocks along the fault zone are composed of cataclastic rocks and mylonites formed in higher, middle and lower temperature. Respectively, both of structural features and rocks have the features of multiple phase's of deformation. The deformation features of main minerals in the high temperature mylonites show that: the quartz has the form of long single crystal and the fabric feature of point maximum near X axis; the feldspar has the form of recrystallization assemblage, They present a high amphibolite-granulite facies with temperature ＞600℃ and depth ＞20km. The deformation features of mylonites formed in middle temperature show that: the quartz has the form of polycrystal banding and the fabric feature of point maximum near Y axis and small circle girdle with Y rotational axis; the feldspar has the form of a coremantle structure, They reflect a high greenschist-lower amphibolite facies with temperature from 400℃ to 600℃ and depth from 15km to 20km.

其中，高温糜棱岩主要矿物变形特征组合为：石英为长矩状或长条状单晶、组构为近X轴的点极密，长石为几乎完全重结晶的集合体，形成温度＞600℃，相当于高角闪岩—麻粒岩相，形成深度＞20km；中温糜棱岩主要矿物变形特征组合为：石英为多晶条带、组构为近Y轴点极密和以Y轴为旋转轴的小圆环带，长石发育核幔结构，形成温度为400～600℃，相当于高绿片岩—低角闪岩相，形成深度为15～20km；低温糜棱岩主要矿物变形特征组合为：石英发育核幔结构、组构特征为近Z轴点极密，长石以碎裂为主，形成温度＜400℃，相当于中低绿片岩相，形成深度为8～12km；碎裂岩则主要代表了地表浅层的变形。

The results showed that the sintered dielectric was a kind of glass-ceramics. The crystals in the dielectric included Hexacelsian and Celsian. Celsian would affect the insulation properties of the dielectric seriously.

研究结果表明，烧结后的介质层是微晶玻璃，主要有六方钡长石(Ba[Al_2Si_2O_8])和单斜钡长石两种晶相，单斜钡长石的存在严重影响了介质层的绝缘性能。

Though stating sandstone thin-section's clastic constituents of outcrop sandstones and core sandstones,collecting sandstones' clastic constituents datas from Jican1 core、Ji3 core、XijiD2 core and JiD6 core,it's judged to the roke type be detritus feldspar sandstone and feldspathic detritus sandstone of outcrop sandstones and core sandstones in studied layer, the mostly roke being detritus feldspar sandstone.

通过统计46块露头砂岩和13块西风井砂岩薄片的碎屑组分，结合收集的鸡参1井、鸡3井、新鸡D2井和鸡D6井9块砂岩碎屑组分含量数据，判断出研究目的层露头砂岩和岩芯砂岩的岩石类型为岩屑长石砂岩和长石岩屑砂岩，主要为岩屑长石砂岩，两种砂岩的岩石学特征基本一致。
