The alternative explanation—that the Neoproterozoic carbonates underwent the same processes of lithification and metamorphism observed in Phanerozoic carbonates—is a simpler explanation for these data, and does not require extraordinary and anomalous behaviour of the C cycle specific to the Neoproterozoic.

新元古代碳酸盐经历了一些成岩或者变质作用，这种变质或者成岩作用与显生宙发现的一致或者基本一致，如果尝试使用这种理论来解释同位素的漂移，我们就不需要特殊和异常的情况发生。

But the geological and geochemical analyses showed that there existed a set of high quality marine source rock in the platform slope facies of Middle Ordovician Pingliang Formation. The oil and gas generated from the source rock of Pingliang Formation was accumulated firstly in the central Palaeo-uplift and its surrounding regions. The thermogenic asphalt in palaeo-uplift carbonate reservoir indicated that oil accumulation completed transition from oil to gas in the Lower Crataceous. Along with the palaeo-uplift axis convection and the formation of westward monocline in the Late Crataceous, gas from the palaeo-reservoir was finally accumulated in the weathering crust of Majiagou carbonate reservoir.

地质和地球化学分析证实，盆地西、南缘台缘深水斜坡相的中奥陶统平凉组存在优质海相烃源岩，其形成的油气最早富集在中央古隆起及其周围；伴随着中央古隆起带轴部的向东迁移和早白垩世末盆地西倾大单斜的定型，平凉组烃源岩在早白垩世生烃高峰期生成的天然气和早期古油藏裂解气，由中央古隆起带向北东方向发生二次运聚，最终在盆地中部奥陶系马家沟组风化壳中聚集成藏，即形成靖边大气田。

So the Late Palaeozoic group in NE China has tremendous potential for oil and gas resources, and should be an important new area for deep hydrocarbon exploration.

鉴于晚古生界潜在的烃源岩发育和叠合盆地特点，东北地区晚古生界具有巨大的油气资源潜力，应成为深部油气资源勘探的重要新层系。

The area reversed intensively in Late Cretaceous and Paleocene, so as to form a series of fault basins, which created a two-layer structure in the upper crust of the Lower Yangtze area.

这是造成下扬子地区海相古生一中生界油气地质勘探高复杂性、高难度性和高风险性的根本原因，也造就了下扬子区海相烃源岩的二次生烃和晚期成藏的优势。

With the exception of rare, relatively well-preserved Phanerozoic shells, this happens to all carbonates.

排除那些稀少的，相对保存完好的显生宙shells，这种所谓的岩化过程基本会发生在所有的碳酸盐岩中。

Through several years' field observation and through the comprehensive analysis on fossils identification, rock geochemical test result and rock property, it is shown that the late Paleozoic radiolarian silicalite and its rock combination are a suite of oceanic basin abyssal facies deposition, and the Bazukeng Formation of Dengshan Group is a suite of early Paleozoic neritic continental shelf bathyal facies deposition.

经数年野外多次观察和对室内化石鉴定、岩石地球化学测试结果以及岩石学特征的综合分析表明，所发现的含晚古生代放射虫硅质岩及其岩石组合是一套洋盆深水相沉积；登山群拔竹坑组，是早古生代的一套浅水陆棚-深水陆棚-半深海相沉积。

Pearl River Mouth Basin, an epicontinental sea and marginal sea basin, is one of depositional basins abundant in oil and gas in China.

该沉积组合反映了张性边缘海盆地的演化特点，盆地演化与资源效应表现在裂陷期、热沉降期及断块升降期的生储盖配置，故勘探目的层段为热沉降阶段所形成的三角洲碎屑岩与陆棚碳酸盐岩。

Aimed at these problem, this paper taked 63 well drilling's rock mineral document and logging document as main analysis object, combined reservoir sedimentology, sequence stratigraphy, logging geology together to research sedimentary system, sequence stratigraphy, lithofacies paleographic, sandbody distribution three dimensional visualization, reservoir character and reservoir sandbody comprehensive evaluation, it offers reference and criterion for Changbei gas field gas reservoir's exploration and development.

针对目前所存在的地质问题，本论文以63口钻井的岩矿资料和测井资料为主要分析对象，运用储层沉积学、层序地层学、测井地质学等多学科交叉的综合研究方法，对长北气田上古生界二叠系山西组2段进行沉积体系、层序地层、岩相古地理、砂体展布三维可视化、储层特征以及储集砂体综合评价和有利区预测等方面进行系统和深入的研究，为更有效地勘探开发长北气田提供科学依据。

Thickish and dead colour mudstone in Nenjiang layer can generate huge amounts of oil and gas. Qingshankou layer is as good as Nenjiang layer, from which oil and gas can be moved to So-layer reservoir.

喇嘛甸嫩江组一段巨厚的暗色泥岩，可以生成大量的油气，因此为喇嘛甸油气自生部分油气，青山口组巨厚的暗色泥岩，也可以生成大量的油气，并可以运移到萨零油层。

The three kinds of associated minerals have implied the characteristic mineral combination of volcanic tuffaceous alteration, which illustrated the reliable deposition of the contemporaneous palaeovolcano events and signified the diagenetic epigenetic alteration records in the volcanic tuffaceous matters transiting from the acidic environment to the alkaline environment.

这三种矿物共生构成火山凝灰质蚀变的特征矿物组合，是同生期古火山事件的可靠沉积和成岩后生蚀变记录，也是火山凝灰物质成岩后生条件由酸性过渡到碱性的古环境转变的标型记录。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
