查询词典 Campanian

An early rift sequence is overlain by a large Late Cretaceous delta, which culminates with the mid-Campanian Rakopi Formation coal measures.

一个早期的裂谷层序上覆有一个较大的晚白垩纪三角洲，后者的顶层则是中坎佩尼阶拉科皮组煤系。

In this area seven microfacies in the Chuangde Fm. red beds can be separated. They are: 1 reddish foraminifera grainstone; 2 reddish microfossils packstone/wackestone; 3 reddish marlstone with microfossils; 4 reddish marlstone; 5 red to variegated floatstone ; 6 reddish shales; 7 reddish radiolarite/ radiolarian chert.In the Yamudok Cuo area, it can be distinguished six microfacies in the redbeds including 1 reddish foraminifera grainstone; 2 reddish microfossils marlstone; 3 reddish shales; 4 yellow-grayish floatstone ; 5 reddish radiolarian chert; 6 reddish chert with radiolaria. The depositional environment of the Chuangde formation can be interpreted from sediments composition, as is deep oceanic basin adjacent to continental slope/rise. The slope/rise setting is indicated by the occurrence of olistoliths and slumped pelagic/hemipelagic limestone, present near the top of the Chuangde Fm.

进一步资料对比研究表明，全球上白垩统海相红层具有以下特征：a上白垩统红层出现在北大西洋、阿尔卑斯、喀尔巴阡、土耳其，向东一直到特提斯喜马拉雅地区和澳大利亚西北角的Exmouth海底高原，横贯整个特提斯和北大西洋；b沉积环境以外陆棚-斜坡和盆地为主，在斜坡环境下多发育有浊流沉积，如Scaglia Rossa和Nietrental组；c有机碳含量普遍很低，0～0.3％之间；d盆地相仅发育红色泥质岩，而斜坡和远洋环境下不仅发育红色页岩，同时还有红色泥灰岩、红色灰岩和红色硅质岩；e北大西洋和地中海地区在Cenomanian-Turonian界线黑色页岩之后不久的Turonian早期就出现红色沉积，而藏南出现在Santonian早期，Exmouth出现在Campanian早期，红层出现似乎有&西早东晚&的趋势。

They not only occur in deep ocean basins such as in the central North Atlantic where they were deposited below CCD, but they extend up the continental slopes and rises, such as in the Alps, including the Gampu area , in the Carpathian Mountains (Austria, Slovakia, Poland, Romania), in Spain, in Turkey and in the Exmouth Plateau (Legs 122 and 123) in northwest Australia.The Upper Cretaceous reddish marlstones in Italy are particularly similar to the Upper Cretaceous Chuangde formation red beds in the Tibetan Himalayas. In summary, the Upper Cretaceous redbeds have several characteristic as follow:(1) very low TOC, only 0～0.3%;(2) wide distribution throughout the Neo-Tethys, from north Atlantic to the west, to Exmouth Plateau to the east;(3) Sedimentary environment of the red beds varied from oceanic basin, to slope/rise, to outer shelf. Most comment is pelagic and hemipelagic.

床得组泥灰岩〓含量0.26～5.62％，远远高于奥地利和意大利红层0.45～0.82％，并出现金属元素高含量，平均达926ppm，以高含量Ba、Cu、Zn、Cr、Ni、Th等元素为特征；2）床得组红层〓相对于定日地区同期海相碳酸盐〓整体负向偏移量达2.0‰，而在其床得组红层内部〓自下而上一直攀升，自-1.5‰～0.0‰之间上升到0.0‰～1.0‰之间；定日贡扎剖面相当于江孜床得组红层的Santonian-Campanian期，〓也出现一弱负向偏移，偏移量达-0.8‰；3）红层内锶同位素〓比值为最低值，同期定日地区也出现锶同位素低值；4）床得组部分层段的泥晶灰岩出现丰富的有孔虫，其中尤以浮游有孔虫最为繁盛，与江孜地区临近的浅海陆棚相的定日—岗巴地区此时期出现自Cenomanian-Turonian界线生物绝灭后的生物辐射期。

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。
