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。
