华北地区自早元古代结晶基底形成以后的沉积盖层发育演化可划分为五个阶段：拗拉槽克拉通边缘（Pt2Pt3）；

In northern China , evolution of the sedimentary sequences since formation of the early Proterozoic crystal basement can be divided into five stages , i.

Te、Se主要富集在与碱性岩浆活动有关的金矿中，Cd主要富集在火山热液型金矿和古老结晶基底内的糜棱岩型金矿中，而Tl则在卡林型金矿中富集。

Te and Se are enriched in those deposits which relate with alkali-magma activities , Cd in those deposits which occur in crystalline basement mylonite , and Tl in Carlin-type gold deposits .

阿尔金造山带上地壳的平均Q值较高（约500），这可能由于结晶基底埋藏较浅，基岩出露，因此地震波在此处传播能量衰减较慢所致。

The upper crust of the Altun orogenic belt has a high average Q value ( about 500 ) . It is likely caused by shallow depth of crystalline basement , outcrop of basement rocks , and slow attenuation of seismic wave .

本文从Au的原始浓集程度、区域浓集程度、Au与有关元素的相关关系、金矿围岩类型分析等方面，研究了辽宁结晶基底Au的分布特征。

In the paper , Au distributing character of Liaoning crystalline basement was discussed on the points of primitive and regional concentration degrees , the correlation relations of elements concerned with Au and analysis on Au country rock types .

南澳的EYRE半岛位于GAWLER克拉通南部，包含了GAWLER克拉通太古界至中元古界结晶基底的主要部分。

The Eyre Peninsula , South Australia , makes up the southern part of the Gawler Craton . It contains a major portion of Archean to mid Proterozoic crystalline basement province of the Gawler Craton .

认为R1界面不仅是结晶基底之顶界的反映，而且STD可能沿着R1界面展布，也即R1界面同时是一条沉积盖层和基底之间的拆离层。

It is suggested that the interface R1 not only marks the top of the crystalline basement but also represents the possible one , along which STD is spreaded , i. e. the R1 interface at the same time is a detachment between the sedimentary cover and the basement .

最终的模型显示塔里木盆地主体的地壳厚度为38～46km，而且塔里木南缘的Moho界面南倾，与结晶基底南倾的角度大体一致。

The final model indicates that the thickness of the main part of Tarim basin varies in the range of 38 ~ 46 km . The model also reveals that the Moho dips southward beneath southern Tarim basin at an angle in concordance with the angle of the crystalline basement .

鉴于白垩纪花岗岩的钕模式年龄（tDM）均集中于古元古代（1.8～2.2Ga），表明花岗岩的源区应限于核杂岩中构成原中地壳下部的古元古代结晶基底岩层。

The source area was proved to be composed of the Paleoproterozoic crystalline basement rocks at the lower part of the original middle crust by the dominantly Paleoproterozoic Nd model ages of the granite and from the comparison with the crustal structure-constitution in East Qinling .
