自生矿物

Quantitative Estimation of paleoaltitude is the objective that geologistes have always sought.The research history of paleohypsometry which uses oxygen and hydrogen isotopic composition of authigenic mineral is overviewed. This method has much more potential to be applied to older periods than Cenozonic.

定量恢复高大地形的古高程是地质学家一直以来追求的目标，将自生矿物中氢氧同位素用作古高程计的历史不长，这种方法还有很大的应用潜力，可用到比新生代更古老的时期。

Carbonate cements are the most abundant authigenic minerals in the Palaeogene sandstones of Lishui sag, East China Sea basin .

碳酸盐胶结物是东海盆地丽水凹陷古近系储层砂岩中最为重要的自生矿物，主要类型为铁白云石和方解石。

The unique geographic position of shelf and marginal sea causes the material supply of seafloor sediments plenteous and the material sources of them diverse. As terrigenous materials being input into the sea continually and a great deal of authigenous minerals coming into being, the sediments can be used to study the change of sea level and the meterail and energy exchange between the sea and the land.

陆架和边缘海独特的地理位置决定了海底沉积物物源的充足与多样性，陆源物质源源不断地通过河流输入到海洋中，同时大量的自生矿物在海洋中生成，因此研究陆架和边缘海海底沉积物，可以为研究海平面变化、海陆之间物质和能量的交换等作用提供信息。

The research on sedimentary facies and diagenesis of the reservoir combined with analyses of diagenesis effect of low permeability resevoir on the reservoir property and with division of diagenesis stages indicates that the genetic mechanism of the low permeability reservoir in this area is the filling and cementation of autogenetic mineral during diagenesis.

该项研究是建立在储层沈积相、成岩作用研究的基础上，通过分析低渗透储层成岩作用对储集物性的影响及成岩作用阶段划分，认为造成本区储层砂岩渗透率较低的主要原因是成岩期各种自生矿物的充填和胶结作用。

It is particular if the supply of detrital materialwas low, when the magnetic susceptibility was mainly controlled by the content ofauthigenic minerals.

特别当陆源物质供应低时，磁化率曲线变化和海平面变化相一致，磁化率主要由自生矿物的种类决定。

While associations consisted principally of zeolites not only can improve the reservoir performance for their diffluent properties, but also form lithological trap incorporated with sealing of areas without corrosion at the margin of sand body.

以浊沸石为主的沸石类自生矿物组合不但易溶能改善储集性能，而且与砂体边缘未被溶蚀区配合遮挡可组合成岩性圈闭。

On the basis of isotope Sr variation, integrated with lithologic association, authigenic mineral assemblage, sedimentary structure and paleontologic evidence, the Shenglihe oil shale is classified into two major sedimentary environments such as tidal flat one and lagoon one.

依据Sr同位素的变化特征，并结合例面的岩性组合特征、自生矿物组合、沉积构造以及古生物标志，将胜利河油页岩划分为潮坪和澙湖两种沉积环境。

The purpose of paper is to describe the petrology character of outcrop sandstones and core sandstones and judge their roke type, compare the similarities and differences of autogenetic mineral、diagenesis types、intergrowth sequence、diagenetic facies、diagenetic phase of outcrop sandstones and core sandstones, provide academic precondition condition for studying better reservoir in studied region.

本次论文的研究目的是描述露头砂岩和岩芯砂岩岩石学特征并判断其岩石类型，比较露头砂岩与岩芯砂岩在自生矿物、成岩作用类型、共生序列、成岩相、成岩阶段以及成岩流体演化方面的异同，为研究区有利储层的研究提供理论前提条件。

From the middle to the south in the research area, the compaction, the pressure dissolves the function and the structure disruption intensity enlarges gradually, the silicon nature agglutinates the content to increase gradually, and the corrosion function intensity reduces gradually. The diagenesis stage is carried on according to the division standards of secondary enlargement degree, pellet contact type as well as porosity type, the authigenic mineral characteristic, agglutinates, the diagenesis of Xujiahe formation is thoughted degree to be intense, which already entered the late diagenesis stage A sub-stage.

从研究区中部向南部，压实、压溶作用和构造破裂作用的强度逐渐加大，硅质胶结物含量逐渐增多，溶蚀作用强度逐渐降低；并根据成岩作用类型、自生矿物特征、胶结物的次生加大程度、颗粒接触类型以及孔隙类型等划分标准，对须家河组进行了成岩作用阶段划分，认为研究区须家河组成岩作用程度强烈，已经进入晚成岩作用阶段A亚期。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
