Abstract:
Chronological and climatic signification of laminated speleothems in North China. Speleothems from North China show that many of them have very fine micro-layer growth. Most of these layers have bi-optical characters that can be observed under fluorescent and transmitted light. Hydrological analysis and radio-isotopic dating demonstrate that those layers are annually laminated. A Holocene stalagmite from Shihua Cave in Southwest Beijing presents thousands of micro-layers which are very similar to tree rings. Based on the measurements of the thickness of annual layers, short-term climatic changes over the last 1,130 years in the Beijing area are discussed.
