沉积岩

Source material of the gold deposit has close connections with the ultrabasic rocks, albite porphyritic dikes, thick|layered dolomite and clastic sedimentary rocks.

金矿的物质来源与矿区的超基性岩体、钠长斑岩脉、厚层状白云岩及各类碎屑沉积岩有密切的关系。

Most foreign scholars believed that T_2 cutoff value of sandstone cores was about 33 ms and domestic scholars generally believed that T_2 cutoff value of domestic sedimentary reservoirs cores was less than 33 ms. In majority study abroad most T_2 cutoff value of carbonatite cores distributed between 90 ms and 100ms, and never saw author relevant reports yet about T_2 cutoff value of vulcanite reservoir cores.

国外研究中砂岩T_2截止值大多在33ms左右而多数碳酸岩岩心集中在90～100ms之间，国内学者普遍以为国内沉积岩储层岩心的T_2截止值要小于33ms，还未见到火山岩油气躲岩心T_2截止值的相关报道。

This paper reports the results of highly precise zircon SHRIMP U-Pb dating of quartz albitite in the volcanic-sedimentary series of the Tuolugou cobalt deposit, Golmud, Qinghai. Analyses of eight spots presented 206Pb/238U ages of 455 to 483Ma with a weighted mean age of 468±9Ma, which represents the timing of submarine volcanic exhalation in this area. Therefore, the age of the host rocks of the Tuolugou ore district is redefined as Ordovician, which implies that regionally the main part of the Naij Tal Group should be Early Paleozoic in age.

青海格尔木驼路沟矿区赋矿火山－沉积岩系中的石英钠长石岩样品锆石SHRIMP U-Pb精细测年结果表明，该岩石具有一组8个测点构成的455~483Ma的206Pb/238U年龄数据，加权平均年龄为468Ma±9Ma，应代表本区海底火山喷流作用的时间，因此重新厘定了矿区内含矿岩系的时代为奥陶纪，同时，这一年龄指示区域上纳赤台群主体的时代应为早古生代。

Recently, a nearly E-W-striking, over 10 km long albitite zone has been recognized for the first time in the Lower Silurian Meiziya Formation in a Lower Paleozoic lead-zinc ore deposit concentration area of the Xunyang basin, South Qinling. It shows a conformable contact and gradational relationships with the country rocks and has thick-bedded and massive, banded, brecciated structures and fine and very fine equigranular and intraclastic textures. It is chemically characterized by enrichment in SiO2, Al2O3 and Na2O and is rich in the trace elements Fe and Mn and poor in the trace elements Co, Ni and Cu. Its ∑REE, LREE and HREE are lower than those of the country rocks and exhibit pronounced Eu depletion.

最近，在南秦岭旬阳盆地下古生界铅锌矿集区内的志留系梅子垭组地层中首次识别出一条近东西方向延伸长达10余千米的钠长石沉积岩带，与地层整合产出，渐变过渡，厚层块状，条带状，角砾状构造，均粒微-细晶结构，内碎屑结构；其化学成分以富含SiO2，Al2O3及Na2O为特征，富Fe，Mn，贫Co，Ni，Cu等微量元素；该钠长石岩的∑REE，LREE，HREE均较围岩偏低，具明显Eu亏损的特征。

The sharp difference suggests that they have different origins: the former comes from allochthonous sapropel-type organisms of the lower strata and is the remains of crude oil, and the latter is autochthonous humic-type organic matter of sedimentary rocks between the basalt layers.

玄武岩中铜矿石沥青的δ13CV-PDB为-27.3‰～-33.2‰，平均-31.97‰，沉积岩中铜矿石碳质的δ13Cv-PDB为-20.2‰～-23.2‰，平均-22.11‰，表明二者无明显成因联系，前者属腐泥型，为石油的遗迹，来自下部地层；后者为腐植型，来自原地沉积的陆生高等植物。

Toppling failure always occurs in anaclinal slopes of layered rock mass, such as thin-bedded sedimentary rocks, foliated metamorphic rocks and those of one single joint set.

倾倒破坏通常发生於层状岩体之逆向坡，如薄层沉积岩、叶理状变质岩及其它含有单组节理之岩石。

The Lazhulong-Jinshajiang ophiolites occurred at archipelagic ocean that opened in Late Permian to Early Triassic and closed until Late Triassic that is a epeirogenic process characterized by "soft collision" that show lentiform and faulting ophiolites, folding marine strata, and accretionary wedge.

该蛇绿岩形成于晚二叠世至早三叠世多岛小洋盆环境，并在晚三叠世末期随古特提斯的闭合而构造侵位，这是一个以软碰撞为特征的造陆过程，伴生蛇绿岩体透镜体化和构造肢解、海相沉积岩褶皱变形和增生楔逆冲作用。

In the early chasmic stage of Luliang Movement, rift-type volcanic-sedimentary rocks of Luliang Group and associate Gaijiazhuang gneissic granite formed. The Gaijiazhuang gneissic granite with age of 2364?

吕梁运动早期阶段为裂陷阶段，形成裂陷型的吕梁群的火山和沉积岩系，相伴产生了盖家庄片麻状花岗岩，形成于2364？

The application of detrital geochemistry to determining tectonic setting and provenance attribute is an important means for basin analysis and also a helpful supplementary or verification method in using coarse detrital rocks to judge the background of provenance.

利用碎屑岩地球化学特征判断沉积盆地的构造背景和物源属性是盆地分析的重要手段，也是对利用粗碎屑沉积岩的组分统计判断盆地源区背景的有益补充和验证。

The sediments are detrital and largely of greywacke facies.

沉积岩为碎屑质，大部分属于杂质砂岩相。
