钙长石

Dark colored, fine-grained, and composed primarily of the feldspar mineral Calcic Plagioclase and the amphibole mineral Pyroxene.

深色，细粒度，主要组成为长石矿物类的钙斜长石和闪石矿物类的辉石。

Other equilibrium phases contain-ing CaO may be monticellite and anorthite.

在渣蚀带内层，反应产物为六铝酸钙和钙铝黄长石。

Parisite is associated with secondary minerals, such as quartz, carbonate minerals, arfvedsonite, albite, chlorite, epidote and clay minerals and has intrinsic relation with reservoir.

氟碳钙铈矿常与石英、碳酸盐、钠铁闪石、钠长石、绿泥石、绿帘石、粘土矿物等次生矿物共生，并与天然气储层有着一种内在的联系。

Actually, the term feldspar refers to a group of closely related minerals which have generally similar composition and characteristics.

严格地说，长石这个名称指的是成分和特征大体相似的一组有密切关系的矿物，它们是钠、钾、钙的铝硅酸盐类。

The garnets in the granitic gneisses from southern Dabie mountain were characterized by riching in Fe and Mn, and pooring in Mg, differing from the garnets in the UHP gneiss and eclogite, which relatively riching Mg. But the plagioclase in the granitic gneisses from the northern Dabie mountain was relative high Ca contenents, their An is 25.2-27.9, within the oligoclase field.

石榴石总体以贫Mg富Fe和富Mn为特征，明显不同于榴辉岩及高压片麻岩中石榴石相对富Mg的情况；而北大别英云闪长质片麻岩中斜长石的钙含量相对较高，An为25.2-27.9，位于奥长石范围内，角闪石中Mg的含量较高，具有壳幔混合源的特征。

In this paper, the petrology, mineralogy and geochemistry of basic-ultrabasic volcanic rock, granite and skarn related to the Sn-Cu skarn-type ore and the vein-type ore in Laochang ore field have been researched systematically, some conclusions are summarized as follows:In Gejiu tin-polymetallic district, the middle Triassic volcanic rocks belonging to calc-alkaline basalt-tholeiite serie, mainly consist of pyroxene, hornblende, feldspar, chlorite and phlogopite; All the granites are peraluminous granites related to the Yanshanian collision-orogeny. Laoka granite closely related to the tin-polymetallic deposits emplaced in the post- orogenic.The metal elements show obviously vertical zones with the variety of skarn types in dimensional extension; The occurrence of garnet skarn and diopside skarn alternately developed in the horizontal zones of the contact between granite and carbonatite are mainly related to two factors: one factor is the infiltration metasomatism of post-magmatic hydrothermal solution, the another is the metrical strata of marble and calcic-dolomite developed in country rocks.

本文重点以老厂矿田中的接触带锡铜矿床和脉状矿床为研究对象，采用化学分析、ICP-MS、X射线粉晶衍射分析、电子探针等测试手段，对本区与成矿相关的基性-超基性火山岩、花岗岩、夕卡岩、电气石-石榴石等进行了系统的地质地球化学研究，研究表明：个旧矿区中三叠纪个旧组地层中的火山岩为钙碱性玄武岩-拉斑玄武岩系列，岩石为辉石-角闪石-长石-绿泥石-金云母组合；本区的花岗岩为过铝质花岗岩，主要与燕山期碰撞造山作用有关，锡多金属成矿与形成时代最晚、分异较好的花岗岩关系密切；本区夕卡岩中的有用共生组份随着夕卡岩类型及其矿物组合的不同具有明显的分带性。

For example, to CaSiO〓, wallastonite and cyclowallastonite could be found simultaneously in glazes between the temperature range of 1125℃±10℃, only wallastonite came out below the range, and only cyclowallastonite appeared above the range. Similarly, melilite structure and clinopyroxene structure connected with crystallization temperature. Usually, higher crystallization temperature contributes to forming melilite with simple structure and lower crystallization temperature contributes to clinopyroxene with complex structure.

如钙的偏硅酸盐，硅灰石、环硅灰石的转变温度区域为1125℃±10℃，组分适当的特定釉熔体，高于此温度出现环硅灰石，低于此温度出现硅灰石晶体结构；同样的，黄长石、辉石的出现也与温度有密切的联系，通常，晶体生长的温度较高有利于晶体结构简单的黄长石出现，晶体生长时温度较低有利于稍复杂的辉石结构的出现。

The hydrates of plain CAS glass are mainly gehlenite hydrate and CSH gel:and the preponderant hydrates or the mixture of CAS glass and gypsum are ettringite and CSH gel.

纯CAS玻璃相的水化产物主要为水化钙铝黄长石晶体和CSH凝胶：而掺有适量石膏的CAS玻璃相的水化产物则为钙矾石晶体和CSH凝胶。

Crystal structure of melilite is limited by MgO content of glazes, also restricted by O/Si ratio. Because of differences of ionic radius and ionic polarization capacity between Ca〓 and Mg〓, suitable O/Si ratio for melilite is influenced by content of CaO and MgO to a certain extent.

结晶釉中黄长石结构的出现，除了和MgO含量相关外，还受O/Si比值的限制；而Ca〓和Mg〓离子半径和离子间的极化能力的差异，使钙镁含量对形成黄长石结构的O/Si比值具有一定的影响。

The adsorption behaviour of chemically different superplasticizers, such as melamine formaldehyde sulphite polycondensate,β-naphthalene sulfonate formaldehyde polycondensate and polycarboxylate, on early hydrating cement phases was studied. For this purpose, pure ettringite AF(subscript t, monosulfate AF(subscript m and syngenite were prepared. The adsorbed amount and zeta potential of early hydration products were measured.

制备了钙矾石AF(下标 t、单硫型硫铝酸钙AF(下标 m和钾长石类单矿物，并研究了三聚氰胺磺酸盐甲醛缩聚物、β-萘磺酸盐甲醛缩合物及聚发酸盐等几种化学成分不同的超塑化剂在其早期水化颗粒表面上的吸附行为。
