  component activity
The design and experimental data on component activity in binary silicate melts are provided.
      
The obtained experimental data are described mathematically in terms of the Wilson equation, and parameters characterizing the concentration dependence of the component activity coefficients are calculated.
      
A representative array of data was obtained, including more than 1600 component activity values at various compositions and/or temperatures.
      
Component activity term is used to determine the boundary of stable areas.
      
Although isoproterenol caused an increase in Δ12-terminal component activity with decreased Δ12-terminal component activity, dexamethasone reduced these isoproterenol-mediated activity changes.

The granite of Mesozoic in Nankou-qian of Fushun is a remelting one, mainly from the deep part of the earth's crust. Through the pulsing and going for many times, the granitic, magma forms the complex with the telescoping structure. In the course of forming and evoluting, the gold ore forms through the activa-ting, migrating and concentrating of gold element caused by the activity of the magmatic evaporating composition.

抚顺南口前中生代花岗岩是重熔型花岗岩,成岩物质源自深部地壳。花岗质岩浆经过多次脉动和涌动形成具有套迭式构造特征的杂岩体。在花岗质岩浆形成和演化过程中,由于岩浆挥发组分的活动,使金元素发生活化、迁移和富集而形成金矿床。

The Ce and Nd isotopic components of five whole rock samples of khongalite from the Huangling area of western Hubei province are reported. Two samples of graphite bearing biotite plagioclase gneiss and one sample of garnet bearing biotite quartz schist have negative ε ce ( t ) values ( -2.5 , -2.1, -1.7) and low negative ε Nd ( t ) values (-0.5, -1.3, -1.6), showing much mantle derive components included in these rocks; A sample of garnet sillimanite quartz schist has a positive...

The Ce and Nd isotopic components of five whole rock samples of khongalite from the Huangling area of western Hubei province are reported. Two samples of graphite bearing biotite plagioclase gneiss and one sample of garnet bearing biotite quartz schist have negative ε ce ( t ) values ( -2.5 , -2.1, -1.7) and low negative ε Nd ( t ) values (-0.5, -1.3, -1.6), showing much mantle derive components included in these rocks; A sample of garnet sillimanite quartz schist has a positive ε ce ( t ) value (+1.6) and higher negative ε Nd ( t ) value(-2.4), suggesting a relative stable sedimentary setting of its primary rocks; A sample of biotite granulite has similar Ce and Nd isotopic components to those of the basement gneiss in this area with ε ce ( t )=+2.2, ε Nd ( t )=-7.7 and Nd model age of (3169±19) Ma. So, the so called "khongalite" in this area might include proto proterozoic Al rich metasedimentary rocks and Archean basement gneiss.

测定了黄陵背斜核部被称作“孔兹岩系”的 5个全岩样品Ce、Nd同位素组成 ,5个样品分别代表该岩系不同层位与岩性。其中两个含有石墨的黑云斜长片麻岩和一个含榴黑云石英片岩样品的εCe(t)都是负值 (分别为 - 2 5、- 2 1和 - 1 7) ,εNd(t)值相对高 (分别为 - 0 5、- 1 3和- 1 6) ,揭示了岩石中含有较多幔源组分 ,原岩沉积环境不稳定 ;一个石榴石矽线石石英片岩的εCe(t)值为 +1 6,εNd(t)值是 - 2 4 ,指示原岩的沉积环境符合形成孔兹岩的地质条件 ;黑云变粒岩的所有特征与基底片麻岩相似 ,εCe(t)和εNd(t)值分别为 +2 2和 - 7 7,Nd模式年龄为 (3169± 19)Ma ,表明它可能不属于古元古代。总之 ,黄陵地区古元古代的沉积构造环境并不全是稳定的 ,在岩系沉积开始阶段和中间某个时期有明显的海底幔源组分活动 ,因此 ,符合孔兹岩形成条件的沉积 -构造环境只在其中一段时间里存在 ,另外有一些地层可能属于太古宙。

Garnet amphibolite, comprising garnet-bearing biotite-amphibole schist,epidote-amphibole schist and plagioclase amphibolite, are present along the China-Pakistan highway section along the western Kunlun Mountains. The medium-grade garnet amphibolites are interleaved with the low-grade biotie-epidote-chlorite schist on both megascale and microscale. Combined with the observation of rock associations and deformation features in the field and the analysis of mineral textures, metamorphic assemblages and reaction...

Garnet amphibolite, comprising garnet-bearing biotite-amphibole schist,epidote-amphibole schist and plagioclase amphibolite, are present along the China-Pakistan highway section along the western Kunlun Mountains. The medium-grade garnet amphibolites are interleaved with the low-grade biotie-epidote-chlorite schist on both megascale and microscale. Combined with the observation of rock associations and deformation features in the field and the analysis of mineral textures, metamorphic assemblages and reaction relations, the authors have deduced that the formation of the high amphibolite facies garnet amphibolite is related to local superposition upon the relatively low grade metamorphism, and this is most prominent in the central part of the shear zone. Fluid volatiles were involved in the presence of the garnet-amphibole-plagioclase assemblage. When the components became more mobile, the clinopyroxene-scapolite-plagioclase assemblage instead of garnet will occur. As to the activity of the components, the mafic component is more active than the felsic component. The protoliths of the garnet amphibolite can be either basic magmatic rocks, such as basalt and gabbro, or sedimentary rocks, like greywacke.

西昆仑中巴公路剖面上多处产出石榴黑云角闪片岩、帘石石榴角闪岩和含榴斜长角闪片岩 ,即石榴角闪岩。不论在宏观尺度还是在微观尺度上中级变质的石榴角闪岩均可与较低级变质的黑云母 绿帘石 绿泥片岩呈条带状相间排列。通过野外岩石组合 构造变形的观察 ,结合室内岩石结构、变质组合和反应关系的分析 ,认为该区石榴角闪岩的形成与较低级变质基础上的局部变质叠加有关 ,这种叠加在构造活动的中心部位最为显著 ,石榴角闪岩的产出表明变质已达高角闪岩相。石榴子石 角闪石 斜长石的形成与一定程度上的流体活动密切相关 ,当流体挥发分组分活动强烈时 ,石榴子石不出现 ,而代之以单斜辉石 方柱石 斜长石组合。在组分活性方面 ,镁铁质组分比长英质组分的活动更为明显。石榴角闪岩的原岩既可以是基性岩 ,如玄武岩或辉长岩 ,也可以是沉积岩如杂砂岩。
