| Abstract: | Grey microstructure of microbanding in thin sections of stalagmite T9501 from Shihua Cave, Beijing was studied. The types
of grey and the morphologic features of organic material were classified. The signification of microbanding and annual layer
was discussed. The standard distinguishing the false annual layer and the multi-year layer is set up, which provides the theoretic
fundaments for paleoclimatic study.
