片麻岩的

This thesis analyzed the basic geological characteristics, petrology, mineral deposit geology, litho geochemistry, and deposit geochemistry of the copper deposit, acquired the following results:(1) According to the metamorphic grade and the metamorphic types of the rocks, suggesting that the mixed granite, granitic migmatite, plagioclase gneiss and hornblende gneiss of the first lithologic member and the second lithologic member in the first sub-formation of Aerbishimaibulake Formation in upper silurian-lower Devonian series belong to Xingxingxia group in proterozoic.

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。

Ion microprobe U-Pb dating of zircons from the tonalitic gneiss and quartz dioritic orthogneiss yielded statistically distinguishable 206Pb/238U crystallization ages of 58.5±0.7 Ma and 63.5±0.8 Ma, respectively.

对2颗片麻岩中的锆石进行了离子探针U-Pb测年，测得英云闪长质和石英闪长质片麻岩中的锆石206Pb/238U结晶年龄分别为58.5Ma±0.7Ma和63.5Ma±0.8Ma。

Hengshan oval-typed gneisses are the augen, streak and striped gneisses, as a result of the dilatation structures of the parallel shear zone boundary, that is the adding of the mafic intrusive rocks of the mantle materiel, and the part melting and auto differentiation of rocks themselves.

恒山卵形片麻岩区，以平行剪切带边界的扩张构造，即地幔物质镁铁质岩席的添加、岩石自身的熔融和自分异形成的眼球、条纹和条带状片麻岩为特征。

This paper proposed that "group complex-formation complex-lithomember" and "gneissic suite-gneiss" in Tecto-lithostratigraphic units belong to mid-types of units between "group-formation-member" or "superunit-unit" and "complex".

Almost no UHP metamorphic minerals survived; granoblastic texture occurs locally to result in a kind of metatexite migmatites due to dehydration melting without considerable escape of felsic melts from the host gneiss.

此外，在组II片麻岩中几乎没有发现特征的超高压变质矿物；尽管没有明显的深色体和浅色体，但在片麻岩内部发现了由细粒矿物组成的长英质细脉。

The banded gneisses underlying the mine field are, as a rule, micaceous, the amount of biotite determining mainly the shades of the bands.

本矿区的带状片麻岩照例富含云母，黑云母的多少决定片麻岩条带的色调。

In the khondalite series in Daqingshan area, Inner Mongolia, Di gneiss association is a independent lithostratigraphic unit characteristic of calcsilicate rocks overlying a Ga-Bi gneiss association and being overlain by a marble association.

在内蒙古大青山地区的孔兹岩系中，透辉片麻岩岩组以钙硅酸盐岩为特征的岩石组合作为一个独立的岩石地层单元产于榴云片麻岩岩组之上、大理岩岩组之下。

Thise granitic gneisses also lack those typical texture that can reflect had undergone UHP metamorphism which are common in paragneisses ,such as biotite reaction rim of phengite.

同时花岗片麻岩中缺少副片麻岩中常见的一些能反映经历过超高压变质作用的特征性结构，如多硅白云母周围的黑云母反应边结构。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
