Black-white-red Climate Cycle and Coal-accumulating Environment
Regarding the coal-forming environment,most scholars believe that it develops in a warm and humid climate.However,modern sedimentary studies have yielded different insights,suggesting that a cold climate is more conducive to carbon sequestration.Resolving this contradiction holds significant scientific importance.Based on the characteristics of modern sedimentatry theory,this paper investigates the distribution patterns of peat,wetlands,and soil organic matter.By combining the distribution of coal across various geological eras,the relationship between coal development and climate as well as latitude is explored.The results indicate that coal,evaporite rocks,red beds,and bauxite,as climate-sensitive sediments,can respectively represent the cold temperate zone at high latitudes,the dry and hot climate at mid-latitudes,and the tropical rainforest climate at low latitudes,indicating different paleoenvironments or paleolatitudes.It is proposed that the development of coal is not related to oxygen deficiency,and the development of red beds and bauxite is not due to oxygen enrichment.The latitudinal shift of the cold temperate zone controls the distribution of coal.Using climate-sensitive sediments,a black-white-red climate cycle is established,and the coal-accumulating environment is defined.
