石炭纪

On the basis of a study of Carboniferous coal measures in the northern foothills of the Dabie orogenic belt and by using the microscopic and ultramicroscopic techniques, the structural coal is subdivided into brittle-deformed coal and ductile-deformed coal.

以大别造山带北麓地区石炭纪含煤岩系为研究对象，利用显微及超微分析手段，将构造煤划分为脆性变形和韧性变形两大类。

The oceanic basin was finally been closed to form a new unified continent in the end of Carboniferous, went through two periods of plate tectonic system and two times of main underthrust collision orogeny.

摘 要：甘肃、内蒙古北山地区从寒武纪初期在前震旦纪统一古陆壳的基础上发生裂解，到石炭纪末洋盆最终闭合形成新的统一大陆，先后经历了两期板块构造体制和两次主要的俯冲-碰撞造山作用。

The Late Carboniferous anomaly never completely closed, so unless the team assigned some Special Forces soldiers to guard it, more Arthropleura could potentially come through.

石炭纪后期的时空易界口并没有完全闭合，所以组织必须派特种部队驻守，否则还可能有更多的古马陆穿过易界口。

The alkline hot-fluid brecciated rocks belt along or in the vicinity of the synfault system are 400km long, which may have shown tectonic geographic location being the most extensively extension at the continental crust in the Qinling at that time.

沿其产出的碱性热流体角砾岩带长达400km，指示了石炭纪在深部地质作用参与下秦岭陆壳伸展最强烈的构造古地理位置。

The Carboniferous is a key period of the Phanerozoic reef evolution. There are mainly six common types of the Carboniferous organic reefs:(1) phylloid algal mounds,(2) stromatolic mounds,(3) coral reefs,(4) Waulsortian mud-mounds,(5) Chaetetes mounds,(6) microbial-algal mounds.

石炭纪是生物礁地史演化过程中一个非常关键的时期，发育的生物礁类型有：叶状藻礁丘；(2)叠层石礁丘；(3)珊瑚礁；(4)Waulsortian灰泥丘；(5)Chaetetes礁丘；(6)钙质微生物－藻礁丘。

The strata between the carbonate rocks of the Chaguoluoma Formation (Devonian-Early Carboniferous) and carbonate rocks of the Xiala Formation consist mainly of clastic rocks with limestone, which are marked by glaciomarine deposits in terms of sedimentation and mixing of Gondwanan and Tethyan faunas in terms of fossils.

古生物群混生的现象为石炭纪—二叠纪的特提斯生物区与冈瓦纳生物区之间的地层和古生物对比建立了一座桥梁。永珠组中上部地层中同时产有牙形石和腕足类，牙形石的研究表明其时代为晚石炭世莫斯科期，而腕足类的研究则表明其为早二叠世萨克马尔期。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
