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。
