Among them, the black shale is rich in graptolite whose thickness is between 20~ 120 m and organic carbon content 0.4%~1.6%, and it mainly has type I organic matter, strong hydrocarbon generation capacity and high thermal evolution degree almost evolved to overmature stage.

四川盆地寒武系底部和志留系底部各存在一套良好的高成熟度、高有机质丰度、类型好的烃源岩，所生成的天然气均为腐泥型有机质形成的油型气，均可作为页岩气的勘探目标。

Most source rocks of the large marine oil-gas fields in domestic and overseas are graptolite shale, oil shale and marl with great amounts of clay mineral, which formed in the deepwater slope environment transferred from tableland to trough.But the carbonate rock is formed in the shallow water environment under good exchanging condition with atmosphere, which causes the low abundance of organic matter and poor-type kerogen.

国内外海相大油气田的烃源岩多为黏土矿物含量较高的泥页岩、油页岩和泥灰岩，形成于由台地向海槽过渡的深水斜坡环境，而碳酸盐岩形成于与大气交换条件较好的浅水环境，是有机质丰度低和干酪根类型差的根本原因。

The carbonate rock-argillaceous rock, limestone-siliceous shale and sea-bottom clastic rock developed from east to west in Pingliang Formation of the western Ordos Basin,which shows the lithological sequence of marine sediment resulted from increasing water depth. The graptolite shale and marl with high-abundance hydrocarbon are formed in the palaeogeographic environment of deepwater slope.

鄂尔多斯盆地西缘中奥陶统平凉组自东而西发育的碳酸盐岩—泥质岩、灰岩—硅质页岩和海底碎屑岩反映了海相沉积因水深变大而形成的岩性序列，含有机质丰度高的泥质和泥灰质烃源岩形成于深水斜坡相的古地理环境中。

Among them,the chitinozoan succession in the Fenxiang Formation in West Hubei is the most complete Early Ordovician (Late Tremadocian to Early Arenigian) chitinozoan succession which have been not ever found in the world so far. The result on the precise subdivisions and corelations of the chitinozoan and graptolite and conodont biozone of Dawan Formation at Huanghuachang strongly supports the Huanghuachang section as the Global Stratotype Section and Point for the base of Middle Ordovician.

其中，有关在鄂西地区分乡页岩中所发现的连续保存的几丁虫序列是目前世界上早奥陶世晚特里马道克世-早阿伦尼克世最完整的几丁虫序列；宜昌黄花场奥陶系大湾组几丁虫、笔石和牙形石精细生物地层划分和对比的研究成果，为宜昌黄花场剖面最终竞争成为全球中奥陶统底界界线层型剖面和点奠定了坚实的基础。

This article provide four usual rocksgranite, limekiln, purple gritstone and red sandstone--that are incline to water and soil loss and reasons of water and soil loss.

本文提出了华南地区常见的4种产生水土流失的岩性(花岗岩、石灰岩、紫色砂页岩和红色砂砾岩)，并在分析了其产生水土流失原因的基础上，提出了治理每种岩性水土流失的具体措施。

They are clay, mud shale, gravel, oil shale, mudstone, schist, basalt, limestone, gritstone, dolomite, breccia, granite, and quartzite. We give the feature curve and distribution feature equation of these rocked landslide.

本论文分别对不同滑体岩性，包括从软到硬的粘土、泥页岩、砾类土、油页岩、泥岩、片岩、玄武岩、灰岩、砂岩、白云岩、角砾岩、花岗岩、石英岩十三种具有代表性的岩土体的滑坡推力和剩余抗滑力进行了模拟分析，给出了它们的滑坡推力和剩余抗滑力分布特征曲线，分布特征方程。

Obviously, many modifications and variations of the invention as hereinbefore set forth may be made of starch at a temperature in the range of from about 75℉.

有些恶化，分散性的结果是控制泥页岩证明了这点增加的产量和10分钟的凝胶强度values。

The Igneous rock is mainly diabase constrution in Luo151 area of Zhanhua Sag, and petrologic types include carbonaceous slate, hornfels, and diabases.

沾化凹陷罗151地区的火成岩油藏主要为辉绿岩建造油藏，岩石类型有碳质板岩、角页岩、辉绿岩等。

The ichthyosaur remains are found in marine shales deposited about 190 million years ago.

人们在黑色的，含沥青的海洋页岩中发现了约 19，000 年前沉积下来的鱼龙化石。

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。
