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.
