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。

It was revealed that the radiolarians in the pebbles dated from Tournaisian to early Visean in age.Geochemical characteristics of the pebbles implied that the radiolarian was deposited in a small oceanic basin,indicating that Kelamaili oceanic basin was closed in the late Early Carboniferous and a quick uprising occurred in the Kelamaili orogenic belt during early Jurassic.
关于两板块缝合的时代，地质学者存在较大争论，有早古生代、泥盆纪、早石炭世不同观点：蔡文俊(1986)根据放射虫研究认为缝合时代为早石炭世[1]，何国琦等(2001)认为克拉麦里造山带是由克拉麦里早古生代洋闭合形成[2]，舒良树和王玉净(2003)根据放射虫动物群对比认为克拉麦里蛇绿岩形成年龄为晚泥盆世法门期—早石炭世杜内
