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。

For Goupitan Hydropwer Station on Wujiang River,over 1 200 anti-uplift anchor pile s are arranged in the water cushion pool to anchor the non-uniform soft rock strata composed of shale,clay rock,silty clay rock,thin layer of marlite and less medium-fine calcareous sandstones etc.

乌江构皮滩水电站水垫塘部位布置了1200多根抗浮锚桩，对页岩、粘土岩、粉砂质粘土岩，及夹薄层泥灰岩和少量中细粒钙质砂岩等不均质软岩层软岩进行锚固，原设计锚桩的间距为2.2m，为了优化设计，缩短工期，在施工前进行了4根锚桩原位抗拔试验，根据锚桩在抗拔过程中周边一定范围内岩体变形沿径向的分布规律，及破坏时裂隙的扩展形态和范围，确定了锚桩的间距，在此基础上提出了锚桩间距的优化方案，并应用于工程施工。

In these limestones, thin layers of limestone are interbedded with mudstones.

对新疆柯坪地区中奥陶统灰岩和泥岩交互沉积地层中的结核状灰岩的沉积环境和形成机制进行了研究。

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。

Buried hills of high density crystalline rock appear as positive anomalies and even outcropping conglomerates will show higher values than surrounding claystones and marls.
