 Compared with other natural materials, speleothems have many superiorities, such as wide ranging distribution, long time span, sensitive to outside environment, full scale information, suitable for U series dating, and play the same important role as the sea deposits, ice core, tree rings do. In particular, Cave dropstones stalagmites offered us a kind of distinctive data source as continental paleoclimate archives. In this paper, the authors reviewed the advance in this field in detail from the stable isotope, stalagmite microbanding, trace elements geochemistry, petrology and crystallography of speleothems. For example, a pure temperature signal has been separated out from the records by utilizing speleothem delta function, and the history of changing vegetation has been traced by using the δ 13 C in speleothem calcite and the variation in the photosynthetic pathway of prairie plants compared to forest species. The advance has unfolded its importance in global change study.
