Colourful Zhangye Danxia is Cretaceous stratum in Gansu, China. Which is folded reddish deposits. It is usually regarded as lake or river sediments. Due to its beautiful colour and unique landscape is known as Chinese "Danxia". In many places of China, the Danxia is a reddish Ca cemented sandstone or conglomerate. However this colourful reddish stratum, similar to Ter tiary Red Clay, is a soil sequence. Of which, many paleosol layers are still contain calcium nodules/or Ca layers underneath. Their pattern of particle size distribution are very similar to that of Quaternary loess and soil. Both sides of syncline shows different colour : one is colourful reddish, but another side of syncline is yellow-gray colour. These data and observation suggest that this Cretaceous stratum is unlikely to be lake or river sediments, but it was very likely a original soil sequence. As a result of the latter chemical weathering, the reddish colour was changed differently, due to theirvarious buried positions where underground water submerged situation.
