On the contrary,the second type of peridotite,which contains metamorphic tectonic fabric,highly depleted incompatible elements(e.
其中,第Ⅱ类橄榄岩的化学成分非常局限,高度富集Co,Cr,Ni,贫乏Ti,V,Cu,Y;亏损不相容元素(K+Na,Al。
In this paper, the distribution, abundance and occurrence states of U in mantle xenoliths are studied by ~(235)U fission track method, and the movement of mantle fluids is revealed by means of U-tracer, which is a representative of incompatible elements in the mantle.
在此基础上进一步把铀作为不相容元素群的示踪剂(tracer),指示地幔流体在深部地幔岩中的活动轨迹。
On the contrary,the second type of peridotite,which contains metamorphic tectonic fabric,highly depleted incompatible elements(e.
其中,第Ⅱ类橄榄岩的化学成分非常局限,高度富集Co,Cr,Ni,贫乏Ti,V,Cu,Y;亏损不相容元素(K+Na,Al。
The problems under consideration include methods for the investigation into the deep crustal compositions, the chemical compositions (and particularly Nb, Ta, Zr and Hf) of the upper crust, and the lateral variation and element compatibility in the crustal chemical compositions.
结合作者对中国东部的研究,探讨了有关大陆地壳化学组成研究中存在的若干问题,包括深部地壳组成的研究方法、上地壳组成(特别是Nb,Ta,Zr,Hf)、地壳化学成分横向不均一性和元素相容性等问
The fractionation and evolution of some incompatible elements in pegmatite veinNo.
对三号伟晶岩脉某些不相容元素的分异与演化进行了研究,结果表明,岩浆作用中的不相容元素Nb、Ta的不相容性在花岗伟晶岩浆演化过程中已大大减弱,Nb、Ta独立矿物如铌钽铁矿、细晶石等能形成于伟晶质熔体的各个演化阶段。
It is pointed out that the metasomatism,melting of the previously formed minerals,and fill-in action of the mantle liquid rich in incompatible elements resulted in the formation of several new kinds of minerals existing in kimberlite in China and South Africa,including yimengite series,mathiasite series,K-Cr priderite,ar.
指出富含硅酸盐不相容元素的地幔流体交代、熔融先期形成的矿物以及充填作用,形成了近年来我国和南非金伯利岩中发现的多种新矿物相,包括沂蒙矿系列、蒙山矿系列、K-Cr柱红石、阿玛科矿、Zr-Ti氧化物(锆钛矿)、REE-Ti氧化物(铈钛矿)等。
