斜长石

The petrogenesis of intrusive rocks is discussed in this paper according to the equilibrium of minerals. It is suggests that in the Shigujian pluton, the designations of plagioclases are 15 - 25, the plagioclases are all oligoclase; the biotites are Mg-biotites, and most of the amphiboles are edenitic amphiboles or edenite; paragenetic ...

结果表明：（1）石鼓尖侵入岩中，斜长石成分较稳定，共生角门石和黑云母为岩浆平衡结晶的矿物；（2）天堂寨和九资河侵入岩中，部分斜长石和黑云母可能为熔蚀残留矿物，角闪石属于火成岩区的新生矿物，可能为斜长石和黑云母发生熔融反应所形成；（3）三个侵入体的岩石均为岩浆成因。

The microstructure and chemical composition of melt formed in process of plastic deformation of gabbro are studied using the transmission electron microscope. The result shows that initial melt occurs at 950～1000℃ in a filmlike shape along the boundary between two plagioclase grains or in the tubules of triangle between three plagioclase grain section.

采用透射电镜对辉长岩塑性变形过程中产生的熔体进行了研究，结果表明，在950～1000℃时出现初熔，初熔熔体呈薄膜状分布于两个斜长石边界，或者呈三角形状分布于3个斜长石之间。

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。

The first type, kamafugite, is plagioclasefree, consisted of Tirich phlogopite, melilite, leucite and nephelite. They have lower contents of SiO2 and Al2O3, but have high TiO2, CaO, MgO contents and K/Na and Mg# ratio whereas the second type, potassic trachybasalt, is abundant in plagioclase and contains no phlogopite, melilite, leucite and nephelite. They have higher SiO2, Al2O3,(Na2O+K2O), and lower TiO2, CaO, MgO, and K/Na and Mg#, in comparision to the first type of rocks.

钾霞橄黄长岩是一种不含斜长石，但普遍含有高钛金云母、黄长石、白榴石、霞石的岩石，全岩化学成分具低SiO2和Al2O3，富TiO2、CaO、MgO和高K/Na、高Mg#值的特征；钾质粗面玄武岩含有大量斜长石但是缺乏高钛金云母、黄长石、白榴石和霞石，全岩化学中SiO2、Al2O3明显高于前者，而TiO2、CaO、MgO、K/Na和Mg#值要比钾霞橄黄长岩低。

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

The study shows that almost all the feldspar in the alkali-granite is perthite, the host-crystal is microcline, the chadcrystal could be either albiter or oligoclase. The Alkali-amphibole is either manganese-magnesia-arfvedsonite or arfvedsonite, and all the alkali-pyroxene is aegirine.

结果表明，该区富碱花岗岩几乎所有的长石均为条纹长石，主晶为微斜长石或高微斜长石，客晶为钠长石或更长石，碱性角闪石为含锰镁质钠铁闪石或钠闪石，碱性辉石均为霓石。

The relationship between the ratio of Ca to Si with shrinkage value was needed to be studied further.The strength of M-AAS was comparatively high, but the flexural strength was regressed in the long term. The compressive and flexural strengthes of 3 days were able to surpass 8MPa and 78MPa, respectively, and compressive strength of 90 days were all around 100MPa, but compared to flexural strength of 28 days, the flexural strength of 90 days was regressed by 19.0%. The high strength property of M-AAS associated with its hydration products and Interfacial Transition Zoo. The main hydration products of M-AAS were microcline and CSH, no calcium hydroxide was found. The coexistence of microcline and CSH worked as micro-aggregate by each other, and no weak ITZ, both resulted in its high strength. The regression of its strength was related to its high shrinkage property, because the crazing caused by shrinkage would decrease the strength, especially the flexural strength.

M-AAS强度较高，但长期抗折强度倒缩。3天抗折和抗压强度分别可超过8MPa和78MPa，90天抗压强度在100MPa左右，但90天抗折强度比28天抗折强度相比低19.0％。M-AAS的高强特性与其水化产物和界面过渡区有关，M-AAS的水化产物主要为微斜长石和CSH凝胶，没有氢氧化钙，微斜长石与CSH凝胶相互填充和配合共同起到强度的作用，M-AAS砂浆中几乎没有发现界面过渡薄弱区。M-AAS的强度倒缩现象与其收缩值较大有关，收缩会引起M-AAS硬化体内部出现微裂缝，使强度下降。

These two ores have contrasting mineral associations: anthothyllite + plagioclase + rutile + magnesiohornblende + alkline fledspar for red ore and anthothyllite + phlogopite + epsode + Rutile for black ore.

根据岩相学观察，认为红色金红石矿中存在如下方向的反应：镁角闪石+碱性长石→直闪石+／-斜长石+／-金云母，斜长石很可能只是过渡相，反应最终将形成直闪石+金云母。

The Chengzihe Formation in Zhangxin area of Jixi basin,Heilongjiang Province is intruded by the algorite sill. The mafic rocks are pure, porphyritic and contain no xenolith.

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
