Colourless albite, black and white nephrite and yellow polycrystalline quartz, can be distinguished bymeans of testing their Raman spectra.

现相同的拉曼谱图，但是其他例如钠长石、黑色软玉和黄色多晶质石英等的相似石拉曼谱图则有

He drew up a geological map containing all information he could gain during his field investigations, such as outcrops of limestone and of cherty material ("chert formation"), overburden, dip and strike of strata, etc.

该地质学家绘制了一份地质图，图中包含其在实地考察期间收集的所有信息，例如石灰石和石英质的突岩层、覆岩层、地层倾向和走向等。

The rock of the shear zone is quartz mylonite which is rich in plastic microstructure.

剪切带岩石以石英质糜棱岩为主，具有丰富的塑性变形显微构造特征。

Fluviatile sands deposited by delta distributaries are quartzose.

三角洲分流中沉积的河流砂是石英质的。

Combined with available data, it is comidered that the sourcerock of biotite--leptynite might be intermediate-acid volcanic material of ca.2.7 Ga, and that of migmatized leptite and quartzite might come from granitic crust older than 3.0 Ga. The iron formation was formed on the continental crust base at about 2.7 Ga, and was immediately metamorphosed for the first time.

结合已有的研究资料可以认为，黑云变粒岩的原岩来自2.7 Ga左右的中酸性火山物质，浅粒岩和石英岩的原岩来自3.0 Ga以上的花岗质地壳物质；含铁建造形成于陆壳基底之上，形成时间约2.7 Ga，并于2.5—2.7 Ga之间发生首次变质作用。

Fluvi tile sands deposited by delta distributaries are quartzose.

In this paper,the basic features of quartz and the theoretic basis for quartz to be taken as a tracer for material source are summarized,and the material source tracing methods to use scanning electron microscope,mass spectrometer,electron spin resonance and cathode luminescence and the feasibility of these methods are introduced in detail.

综述了石英的性质和它作为有效指示剂来示踪物源的理论基础，进而详细介绍了使用扫描电镜、质谱、电子自旋共振和阴极发光等仪器对石英矿物的表面微结构、氧同位素比值、形成年龄和阴极发光颜色等特征进行研究来追踪物源的方法以及这些方法的可行性。

The invention discloses a method for treating the quartz beach sand which is polluted by spilled oil.

本发明公开了一种受溢油污染的石英质海滩砂粒的治理方法。

Cold places like cold stone substrate, transparency, quality nourish, low hardness, gloss strong line better varieties; soft ground nearly frozen to substrate, but the lack of transparency; just manner, then the hardness high, often with quartz quality of sand screw; hard the worst quality, hardness, opacity, gloss weak, often more impurities, and rock in the gravel. 3, defects, including impurities and cracks in the stone.

冻地的底质似冻石、透明度高、质细润、硬度低、光泽强，系较佳品种；软地的底质接近冻地，但透明度不足；刚地，则硬度偏高，常含石英质砂钉；硬地的品质最差、硬度大、不透明、光泽弱，常有较多杂质和围岩中的砂砾。3、瑕疵，包括石中的杂质和裂纹。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
