Oil shale is an important potential energy,which has huge reserves.If converting it into calorific capacity,the reserves would be ranked the second in fossil fuel in China,just following coal.If converting it into shale oil,the reserves of oil shale in the world is about 475 billion tons,almost 5 to 4 times of minable reserves of native oil in the world.

油页岩是一种重要的潜在能源，储量巨大，若折算成发热量，它的储量在化石燃料中仅次于煤而列第二位；若折算成页岩油，世界上油页岩储量约为4750亿t，相当于目前世界天然原油探明可采储量的5.4倍，因此油页岩的勘探与开发已成为世界性新能源开发的课题。

According to the lithologic correlation,the feature of basic sequence,fossil assemblages and isotope assaying ,mass formation within Hercynian period in Hongliuhe area is composed of Hongliuhe Group made up of detrial and volcanic rocks of marine facies , carbonate and continental molasse.

据岩石组合、基本层序特征，结合生物化石鉴定和同位素测年结果，红柳河地区海西期物质建造由红柳河群海相碎屑岩、碳酸盐岩、火山岩建造和陆相磨拉石建造组成，主期变形形成主干褶皱———红柳河向斜及伴生构造，变形机制为纵弯褶皱作用兼具一定压扁特点，总挤压收缩率达 40 %～ 70 %，反映了造山后强烈陆内收缩变形特点。

On the base of mycotrophic status of different taxa, evolutionary stages and different ecophenotypes of pteridophytes, and refering to the relevant fossil materials and molecular evolution of VA mycorrhizal fungi , it could be concluded that

从不同分类群、不同进化阶段和不同生态类型的蕨类植物VA菌根营养状况以及有关的化石资料和VA菌根真菌的分子进化资料，可以初步得出

Nannoplankton Extinction and Origination Across the Paleocene-Eocene Thermal Maximum - Rare plankton became extinct when atmospheric CO2 levels rose abruptly 50 million years ago, whereas those sensitive to ocean acidification caused by the rise survived.

In this paper, the biological and organic geochemical methods were applied together to study the characteristics of thermal simulant products of calcifiied and noncalcified coccolithophore, fresh and dead Pediastrum boryanum, autotrophic and heterotrophic Chlorella protothecoides, as well as Synechocystis.

本论文综合利用了生物学与有机地球化学的分析实验手段，研究了钙化/非钙化颗石藻、新鲜/死亡盘星藻、自养/异养黄化小球藻和聚胞藻热模拟产物的地球化学特征，对比解剖了胜利油田孤南洼陷富含藻类化石的烃源岩的地球化学特征，探讨了藻类生源与烃源岩间不同生物标志物表现及对应关系，研究发现

To meet the growing energy demands of the global economy, all sources of energy — including conventional and nonconventional fossil fuels, renewable energy, and increased efficiency and conservation — will be needed.

为适应全球经济不断增长的能源需求，所有的能源-包括常规和非常规的化石燃料、可再生能源以及提高的效率和保存-都是必要的。

The octoradial Ediacaran macrofossil recently reported to be preserved as casts and molds in the Rawnsley Quartzite in South Australia was classified as belonging to the same taxon.

最新报道的南澳大利亚Rawnsley石英岩层中也发现相似的印痕化石，被归为同一类别，表明华南的&庙河生物群&与澳大利亚的&伊迪卡拉生物群&时代相当。

And whether is it necessary to redefine the geotectonic pattern in southern China? In 1993, the authors discovered firstly the late Paleozoic radiolarian silicalite in the "Shuangqiaoshan Group", which, as we know, is a block within the ophiolitic mélange. In 1996, the authors discovered again the late Paleozoic fossils in the other rocks of "Shuangqiaoshan Group" and "Zhitang Formation" of Lower Sinian Series in the ophiolitic mélange. At the same time, the authors discovered firstly the early Paleozoic chitinozoa fossils.

因此，再次将&板溪群&是否是前震旦纪的一个变质地层单位、江南古陆是否存在以及华南大地构造格局是否需要重新厘定等问题提了出来。1993年笔者于赣东北蛇绿混杂岩带内的&双桥山群&岩块中，首次发现了含晚古生代的放射虫硅质岩。1996年又在该混杂岩带多处的&双桥山群&岩块和&下震旦统志棠组&中找到了含晚古生代的放射虫硅质岩，还首次在&登山群拔竹坑组&中发现了早古生代的几丁虫化石。

Founded in 1963, the International Research Group on Ostracoda is an interdisciplinary, international organization of about 400 research scientists studying living and fossil Ostracoda.
