陆表海

Based on studies of ore - bearing rocks and geochemistry, it is suggested that bauxite deposits in western Jiyuan were sediments in lake - environments after transgression when North China Block turned from peneplain in early Paleozoic to epeiric sea in late Paleozoic.

中文摘要：文章在对含矿岩系岩石组合、地球化学分析的基础上，认为矿区铝土矿形成于华北地块从早古生代准平原状态向晚古生代陆表浅海过渡时期，早期海侵之后的陆地湖泊环境中。

Therefore, Changning-Menglian ocean basin is a small-scale in tercontinental rift ocean basin, and formed by pull-apart and spreading on the basis of the epeiric sea after Caledonian movement.

因此，昌宁-孟连带洋盆为一宽度不大的小型陆间裂谷洋盆，是在加里东运动之后的陆表海基础上经拉裂扩张而成。

The rock types include limemud limestones, bioclast limestones, oolites, intraclast limestones and dolomites, indicating a typical set of epeiric sea carbonate platform or submerged platform deposits.

岩石类型包括泥晶灰岩、生物碎屑灰岩、鮞粒灰岩、內碎屑灰岩、白云岩等，为一套典型的臺地或沈没臺地型陆表海碳酸盐沈积。

Ga. This decline might be related to the formation of a stable epicontinental sea with a shallow water environment.

这一降低可能与在此阶段形成的稳定浅水陆表海环境有关。

4Ga. This decline might be related to the formation of stable epicontinental sea characterized by shallow water environment.

这一降低可能与燕山盆地进入稳定的浅水陆表海沉积环境有关。

Basing on the analysis of epicontinental sea carbonate platform sequence stratigraphy of Cambrian in north China, the paper puts forward 6 points which shall be noticed on the study of sequence.

根据对华北地台寒武系陆表海碳酸盐台地层序地层分析，提出了露头层序工作的方法以及应注意的六项问题。

The sedimentary formation can be summarized as epicontinental sea filling sequence, offshore debris lake basin sequence and inner continental lake basin sequence etc.

在此基础上，对沉积层序地层进行了探讨，划分出了陆表海、近岸碎屑湖盆和内陆湖盆等3个层序组以及18个沉积层序，建立了研究区层序地层学格架。

For example, the eastern North China tableland is Early Paleozoic restricted oceanic tableland, while the western is the Paleozoic epicontinental tableland.

如华北台地，其中东部为早古生代局限海台地，西部为古生代陆表海台地；四川陆表海台地；塔里木、江南和西藏陆缘海台地。

The rock formation and isochronic sequence stratigraphic correlation framework have been set up which shows the sedimentary sequence in both Luxi and Jiyang depression is similar to each other, being of the same sequence architecture of'duality structure'but a bit differences in sedimentary system.

以多重地层划分及层序地层学理论为指导，运用沉积学、古生物学、地球化学、地球物理学方法和资料对研究区石炭二叠纪陆表海聚煤盆地的沉积层序进行了综合识别分析。

During the development peroid of Doushantuo Formation source rocks, the areas studied belong to arenaceous pelitic facies, open platform facies. Until Dengying Stage, the area mainly belongs to restricted platform facies. During early Lower Cambrian, the areas belong to mesa-basin sedimentary facies and gradually developed to open platform-restricted platform facies. During Lower Cambiran, the areas belong to open sea shelf facies-open marine platform facies.

陡山沱组烃源岩发育时期，研究区处于近岸砂泥坪相区及开阔台地相区，至灯影期，主体处于局限台地相带；早寒武世早期，研究区主要处于台地—盆地沉积相带，逐渐演变为开阔台地至局限台地相带；下寒武统在区内以广海陆棚—开阔台地相为主；奥陶纪末—志留纪早期，经历了非补偿滞留还原海盆—正常陆表海/深水陆棚海—残留海—陆相沉积环境的变迁。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
