The khondalite series within Kongling Group in Yichang City, Hubei Province are composed of aluminum-rich schists-gneisses and garnet-sillimanite-quartzites, leptynite and mafic granulites, its protoliths are clay, sandstones-greywacke and marlite. REE distribution patterns of aluminum-rich gneisses incline NASC, Eu show negative abnormity and Ce displays no abnormity in chondrite-normalized REE distribution patterns.

湖北宜昌崆岭群孔兹岩系由富铝片岩－片麻岩及榴线英岩类、长英质岩类及镁铁质麻粒岩类组成，其原岩分别为黏土岩、砂岩－杂砂岩和泥灰岩，富铝片麻岩的稀土元素分配型式接近北美页岩组合样，Eu显示负异常，而Ce基本无异常。

The growth of C. japonica grow well in the Limy dolomite, then in quartz sandstone, sandstone and shale with coal, purple sandstone and metamorphic sandstones, but poor in the quaternary clay.

日本柳杉在灰质白云岩上生长最好，在石英砂岩、煤系砂页岩、紫色砂岩、变质砂岩上居中，而第四纪粘土生长较差。

Marrella is one of the most common fossils in the Burgess Shale, and was probably the first soft-bodied organism noticed by Walcott.

Marrella 是一种最常见的化石布尔吉斯页岩，并可能是第一次软健全的有机体注意到了沃尔科特。

This Marrella example uses reflected light, making the fossil look light-coloured against the dark shale/slate background.

这 Marrella 例如使用反射光，使化石期待浅色的深色页岩/板岩背景。

The sedi mentary formation formed in the stage was predominantly composed of marine sandstone, siltstone, shale and lime stone.

在此阶段内形成的地台构造层主要以海相砂岩、粉砂岩、页岩和灰岩构成。

A green, gray, or red metamorphic rock, similar to slate but often having a wavy surface and a distinctive micaceous luster.

千枚岩，硬绿泥石一种绿色、灰色或红色变质岩，与页岩相似，只是表面通常起伏不平，有明显的云母光泽

Oil shale is an important potential energy,which has huge reserves.If converting it into calorific capacity,the reserves would be ranked the second in fossil fuel in China,just following coal.If converting it into shale oil,the reserves of oil shale in the world is about 475 billion tons,almost 5 to 4 times of minable reserves of native oil in the world.

油页岩是一种重要的潜在能源，储量巨大，若折算成发热量，它的储量在化石燃料中仅次于煤而列第二位；若折算成页岩油，世界上油页岩储量约为4750亿t，相当于目前世界天然原油探明可采储量的5.4倍，因此油页岩的勘探与开发已成为世界性新能源开发的课题。

Therefore, palaeoclimate, palaeogeographic conditions, sedimentary environment and tectonic action jointly contributed to the formation and effective production of shale gas in North America.

因此，古气候、古地理条件以及沉积环境、构造作用等因素的综合，使得北美页岩气资源形成并不断得到有效开发。

For the sake of getting over the trouble of the manufacture of soft rock specimens, it developed a kind of equivalent material whose original components are paraffine, marble sand and vaseline etc .

为了克服软岩试件加工成型的困难，研究了一种以石蜡、大理石砂和凡士林等为原料的软岩相似材料，该材料与自然界泥页岩等较软弱岩类具有十分相似的力学性质，适合于作软岩的流变试验研究。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
