查询词典 Palaeocene

The studies have showed that some geological events, such as Late Palaeocene Thermal Maximum, had possibly related to the decomposition and outgassing of gas hydrate. Except the strong and abrupt methane releasing in the geological history,...

由于天然气水合物中甲烷逸出对全球气候影响的研究刚刚起步，还缺乏海洋沉积物和海水中甲烷传输的恰当模式，甲烷在海水中的溶解度、甲烷的氧化作用及上升流等因素对其的影响程度，以及它对大气甲烷和二氧化碳浓度变化的具体贡献等目前还很不清楚，亟需深化研究。

Also, the temperatures of surface waters during the Palaeocene/Eocene thermal maximum (approximately 55 Myr ago) appear to have been substantially warmer than previously estimated.

新世纪早期（55百万年前）水表温度比先前估计的也要高。

The study offers a "really big piece of evidence" to researchers trying to estimate Palaeocene climates, says Lisa Sloan, a climate scientist at the University of California, Santa Cruz.

这项研究提供了一个&很有说服力的证据&，这给研究者试着估计古新世的气候。丽萨说道--加利福尼亚大学气候科学家。

The heavy mineral located in sand between Palaeocene and Oligocene of 20 drilled wells in Tangyuan Rift are analyzed by relative analysis and polymer with Q type analysis and indicates that,in test areas,variation rules of heavy mineral combination are vertically controlled by structural factors,while horizontal distribution is influenced by source rock property in source areas.

采用相关分析及Q型聚类分析方法对汤原断陷20口钻孔古新世—渐新世的砂岩中重矿物进行统计分析，指出了研究区重矿物组合纵向上变化规律明显受构造因素的控制，横向上的分布受物源区源岩性质的影响。

There are four hydrocarbon source rocks, Palaeocene, Eocene, Oligocene and Miocene.

西湖凹陷发育古新统、始新统、渐新统及中新统四大烃源岩系。

Based on the relationshiphydrocarbon distribution between formation condition of S_(2+3) oil layer in the west slope region, the resultshows that hydrocarbon formation and distribution were mainly controlled by trap development,relationship trap between the room place of oil-gas migration pathway, convergence area of centrifugalflow and endocentric flow, etc. Oil-gas accumulation period is the end of Nenjiang formation sedimentation,Mingshui formation sedimentation and the early of Palaeocene.

根据西斜坡区萨二、三油层油气分布与油气成藏条件关系综合分析得到，西斜坡区萨二、三油层油气成藏与分布主要受圈闭发育、圈闭与油气运移路径空间位置关系、向心流与离心流交汇区等因素的控制，油气成藏时期除嫩江组沉积末期，还有明水组沉积末期—古近纪初期。

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.
