海拉尔盆地乌尔逊-贝尔凹陷的构造特征及其对油气成藏的影响

海拉尔盆地乌尔逊-贝尔凹陷是叠置于内蒙-大兴安岭古生代碰撞造山带的中新生代盆地,主要发育白垩系和第三系、第四系,其中以下白垩统为主。乌尔逊-贝尔凹陷在中新生代经历了多期变形作用,构造特征十分复杂,主要发育4个方向的构造带,其中北东向、北东东向和南北向断层带形成较早且长期活动;北西向断层带形成较晚,对上述三个方向构造主要起改造作用。研究区的构造不仅影响了烃源岩的分布、油气运移和聚集,而且影响了圈闭的形成和油气分布,是研究区有利的油气聚集带。     

Effect of pressurization positions on the consolidation of dredged slurry in air-booster vacuum preloading method

Abstract

Air booster vacuum preloading method is a useful method for strengthening dredged slurry. Though this method is improved effectively with the rapidly developed technology, the problem of inadequate reinforcement in deep layers of soil is still in existence. In view of the fact that the pressurizing system can effectively enhance the reinforcement effect. Therefore, this paper discusses the reinforcement effect of a new pressurizing system that put the booster pipeline at the bottom of soil. Meanwhile, another problem is found that the booster pipeline type was single at present, the action effect of different kind of booster pipeline is still uncertain. In this paper, laboratory experiments are performed to investigate the influence of two kinds of pressurization position and two types of booster pipeline on the treatment of five dredged slurry samples. The test results showed that though the vertical pressurizing system can be good to reinforce the middle soil layers, but the bottom pressurizing system can make the whole soil layer more homogeneous. Furthermore, the difference of the two kinds of booster pipeline on the reinforcement effect of soil is not significant. These results provide good guidance for practical application of air booster vacuum preloading in land reclamation project.     

湖北秭归庙河地区震旦系陡山沱组微化石的新发现

庙河地区震旦系陡山沱组燧石中的激化石，前人曾有过报道。但是，所报道的激化石组合与已知峡区的其他震旦系剖面陡山沱期微化石明显不同。具刺疑源类以ＭｉｃｒｈｙｓｔｒｉｄｉｕｍｔｌａｎｃｅｄｅｔｕｍＬ．Ｙｉｎ为主（样品号：Ｈｍ８０—１４—２，Ｙｉｎｂｏｒｎｉｎｇ，１９８５）。１９９２年作者等重新研究了庙河震旦系沿江剖面，系统采集了燧石样品。结果，并未在陡山沱组发现上述微化石组合，而在寒武系底界附近的燧石夹层中，发现了与其相同的微化石群，因而，对上述微化石组合出现的层位提出质疑。最近，作者再次对庙河地区陡山沱组燧石     

北太平洋柔鱼不同阶段角质颚微量元素含量差异及洄游路径推测的应用

大洋性鱿鱼的洄游路径能够给我们重要的信息,帮助我们了解其时空分布的变化。标记-重捕和电子标记方法在施行过程中仍存在一些问题。头足类的硬组织,如角质颚,有着稳定的形态特征和类似耳石的连续生长纹,同时包含丰富的生态信息,可以为我们研究物种的时空分布提供相关信息。本研究中,我们以北太平洋柔鱼为研究对象,基于不同角质颚生长阶段进行取样来重建鱿鱼的洄游路径。研究结果认为,通过电感耦合等离子质谱仪（LA-ICP-MS）取样,发现角质颚的喙端矢状平面（RSS）检测到9种微量元素。针对上述几种元素,发现不同生长阶段的磷（P）、铜（Cu）和锌（Zn）存在显著差异。利用钠（Na）、磷和锌与海表面温度（SST）建立线性回归模型。基于贝叶斯模型,计算出不同时期柔鱼出现的较高概率的海域。结合不同时期的高概率分布海域,建立起柔鱼的洄游路径,该结果与前人研究结果一致。本研究也证实了角质颚可以为研究大洋性柔鱼的洄游路径提供有效的信息。

Ripple/dune to upper stage plane bed transition: Some observations from the ancient record

In two Proterozoic sandstones, of the Indian shield cross-stratification and cross-lamination are observed to grade continuously into parallel-laminations often bearing parting lineations. These are interpreted as having resulted from a gradual transition from ripple/dune to upper stage plane bed structures. During the transition the inclination of the cross-strata diminishes and their shape changes from concave-up to sigmoidal. The sigmoidal cross-strata are characterized by well defined topsets, foresets and toesets and the topsets bear parting lineations. In the course of the transition sigmoidal cross-strata may give way either to horizontal parallel-lamination or inclined parallel-lamination. In the former the toesets of the successive sigmoidal cross-strata thicken and the thickness of the cross-strata beyond the brink point (the junction between the topset and foreset) tends to become uniform until a plane-bed state is reached and horizontal parallel-laminations are formed. In the latter the topset of the successive sigmoidal cross-strata increases in length at the expense of the foreset and toeset until the brink point ceases to exist so that only the topset laminations prevail and appear as inclined parallel-laminations. These transitions presumably result from a gradual increase in flow intensity beyond the stability limits of ripples/dunes. The progressive morphological changes of the cross-stratification over the transition are attributed to changing fallout patterns on the lee face of the bedforms in response to increasing flow intensity. Preservation of the records of such transitions suggests an abundant supply of sand grade sediments from suspension during the transition, shaping the sediment concentration profile over the bedforms and facilitating turbulence suppression. The variation in the pattern of transition from sigmoidal cross-stratification to parallel-lamination may be the result of different rates of sediment feed from the prevailing suspended sediment load in the two instances.
