热河生物群

热河生物群的研究还具有很大的潜力，而对化石的科学发掘和保护的任务还十分艰巨。

The study of the Jehol Biota has a long way to go , while the scientific administration and protection of the fossil sites remains a pressing issue .

同位素测年技术的广泛应用，表明热河生物群属于早白垩世，在地球上延续了大约2千万年。

The applications of various isotope-dating techniques have indicated that the Jehol Biota belongs to the Early Cretaceous , living on earth for around 20 million years .

C阶段为火山活动间歇期和热河生物群的繁衍；

Stage C is " the dormant of volcanic activity and the development of Jehol biota ";

进一步研究发现，火山活动导致了古生态环境中As、Hg、S等有毒、有害元素异常的增高。热河生物群灾难事件的发生层位（如SYP1的39层）多是古生态环境的突变层位。

A comprehensive research confirms that the volcanic activity resulted in the high level of toxic element abnormal , such as As , Hg and S. The disaster beds of Jehol Biota correspond to the beds with paleo-environmental mutation .

A Holy Journey of the 20_ ( th ) Century & From a report about the Jehol Biota (ⅱ)

辽西地区是我国中生代陆相地层和热河生物群研究的经典地区之一，已有80多年的研究历史。

Western Liaoning has been one of the classic areas for studying the late Mesozoic strata and the Jehol Biota for over eighty years .

辽西地区早白垩世早期义县组以产出精美的热河生物群而闻名于世，热河生物群研究的每一个重要进展都引起国内外科学家的极大关注。

The Yixian Formation becomes world well-known by fancy Jehol bita fossils , each signify headway of bita research would bring both here and abroad scientists'attention .

通过地球化学异常分析发现，热河生物群的古生态环境曾出现过氧化-还原环境的剧烈变化以及湖盆盐度和水位的动荡。

The analysis of geo-chemical abnormal indicates that there were mutations of paleo-environment at the aspect of oxidation-reduction system , as well as the saltness and water level of the paleo-lake .

化石发掘和微量元素分析表明，热河生物群经历了集群死亡和快速掩埋，火山活动的有毒气体是生物灾难事件的主要因素。

Excavation and trace element analysis indicates : Jehol biota experienced mass mortality and rapid burial ; toxic gases of the volcanic activities are the main factors of biological catastrophic event .

内蒙古宁城县毗邻辽西、冀北，是热河生物群研究程度比较高的地区。

Ningcheng is in the southeast of Inner Mongolia , adjoins the west areas of Liaoning province and the north areas of Hebei province , which are famous for the Jehol Biota .

野外填图证实，四合屯及其周边地区热河生物群化石主要产于义县组下部的沉凝灰岩和中部的内陆湖泊相沉积岩之中。

Based on the field mapping , we recognized that " Jehol Biota " fossils occurred mainly in tuffite of the lower part and inner lake sedimentary beds of the middle part of Yixian F.

辽西地区丰富的热河生物化石群，尤其是带羽毛的恐龙及珍稀鸟类的发现，各种类动物大面积死亡而其化石又完整地被保存下来，引起地学界极大关注。

It causes domestic geoscientists ' great concern that the abundant biological fossil group of Rehe in western Liaoning was found , especially the dinosaur with feather and rare birds were discovered , with various animals ' large-area death but keeping remains intact .
