金伯利岩

Mafic granulite and gabbro xenoliths are also found in the same kimberlitic pipes from the Eastern-North China platform, and suggest that multi-accretion events took place. The gabbro was formed lighly earlier with the host kimberlite. The underplating of the mafic magmas was related to the continental orogeny in the late middle-Ordovician Period.

金伯利岩中强烈变质的基性麻粒岩以及变质不彻底的粗粒辉长岩在同一岩管中共存，表明华北古老岩石圈地幔所发生的多次增生作用事件，特别是后者的变质不彻底变质作用暗示其形成时代与金伯利岩相近，这种基性岩浆的底侵作用与华北地台中奥陶世晚期的造陆抬升有关。

The name comes from Kimberley, the place in South Africa were diamonds were found in the nineteenth century.

这种原岩叫金伯利岩，这个名字来源于南非的一个叫金伯利的地名，十九世纪人们在这里发现了钻石。

From 1970's,there are 111 kimberlite veins or pipes to have been found.As much as half of Chinese original diamond reserves are located there.

从20世纪70年代发现金伯利岩以来，该区已发现111个金伯利岩脉，原生金刚石矿储量占全国总储量的一半以上。

The mine, established in 1903, is one of 30 or so kimberlite diamond mines in the world, and is believed to be still the world's second-most-valuable diamond resource.

自从1898年汤玛斯库里南爵士在这里发现可能富含钻矿的金伯利岩石以来，小镇就依赖钻石生意生存发展。1903年建成的库里南钻矿是世界上约30个金伯利岩钻矿之一，在世界上最有价值的钻石资源中仍居第二位。

In the near term, the factory will treat four million tons extracted from the Catoca region, which is regarded as the world's fourth largest kimberlite

近期，该工厂将处理400万吨从卡托卡地区开采的金伯利岩。卡托卡地区的金伯利岩储量世界排名第四。

From 1945, the Soviet Union I in the Siberian Platform for diamond prospecting survey, after 10 years of work until 1954, along daldyn River with pyrope as a symbol of placer minerals recourse, discovered the first kimberlite Yan Bin -"Flash"...

从1945年开始，苏朕在西伯利亚地台进行金刚石普查找矿，经过10年的工作，直到1954年沿达尔登河用镁铝榴石作为标志矿物进行重砂追索，才发现第一个金伯利岩岩筒-"闪光"。。。

Www.ebigear.com 更好的英语互动平台(1) This is good news for the mine's 1,000 or so employees and for the town, which has depended on the diamond business since Sir Thomas Cullinan discovered a prospect there in 1898 that contained kimberlite, a rock that can be rich in diamonds.

这对于这个矿的1000名左右的雇工以及这个小镇来说是个好消息，这个小镇从1898 年Thomas Cullinan爵士发现该矿含有金伯利岩(可能富含关关的一种岩关)后，就一直依赖关关生意存活。

Natural diamonds often exist in the Kimberlite pipes of the mantle, where often contain the inorganic elements--- sulfur. So the inclusions of natural diamonds are always carbonate minerals and sulfide. Undoubtedly, the study of the additive sulfur action in the course of synthesizing diamond will further our understanding the reason of natural germ formation.

天然金刚石多产生于地壳中的金伯利岩和钾镁煌斑岩，该岩层中含有非金属元素硫，天然金刚石中的包裹体通常为硅酸盐矿物和硫化物[41]，因此研究添加剂硫在合成金刚石中的影响是认识天然金刚石成因的重要方面。

The difference between the lithosome shape, distribution of kimberlite and the physical natures of adjacent rock decides the size, intensity of anomaly and the reflecting degrees. The anomaly range of elements Cr、Ni 、Nb has the direct corresponding relationship with the shape of kimberlite pipe or vein.

综合物化探异常与矿体吻合较好；金伯利岩岩体形状空间分布与围岩的物性差别，决定了异常大小强弱、反映明显程度； Cr、Ni 、Nb的元素异常范围与金伯利岩管的形状有直接的对应关系。

Heat flows derived from garnet, chromite/chromium-spinel and pyroxene of xenoliths, xenocrysts in Mengyin and Fuxian kimberlites are higher than 40mW/m〓 calculated from the pyroxene inclusions in diamonds, and the range of pressure is 20～40kb (equivalent to 65～130km). Metasomatism (as indicated by yimengite and lindsleyite in Mengyin) is very strong in this depth range. Lherzolite, wehrlite, and diamond-free high-Ca harzburigite around the world are derived from this depth also. The observation suggests that the low-Ca harzburigitic environment for diamond stability had been changed significantly when the kimberlitic magmas erupted. This resulted from fluid interaction with harzburigite. The geotherm of the Cenozoic lithospheric mantle beneath Eastern-North China platform is higher than oceanic one. The temperature from the interior of the Tan-Lu faults is higher than that from apart off the fault.

除金刚石中的辉石温压投点落于40m W/m〓占地温线上外，捕虏体及捕虏晶中石榴石，铬尖晶石及单斜辉石的投点均偏离该地温线，显示较高的地温特点，而且捕虏体及捕虏晶的压力范围多在20-40kb(相当于65-130km)间，该深度范围内地幔的交代作用特别发育，如蒙阴大量发育的沂蒙矿、钛钾铬石等就发育于该深度范围，世界范围内不含金刚石的高钙方辉橄榄岩、二辉橄榄岩、异剥橄榄岩也分布于该区中，一方面表明捕虏体的主要取样位置已不在金刚石稳定区中，另一方面也表明金刚石稳定的橄榄岩环境，在金伯利岩侵位并捕虏他们时已发现了明显的改造，这种改造作用主要是通过长期的熔流体与先存的橄榄岩相互作用的结果。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
