One of the main advantage of speleothems in terms of paleoclimate reconstructions is the opportunity to date them very precisely. However, the presence of detrital material can hamper this precision a lot. In order to avoid this problem we tried a coupled approach of Laser Ablation and our standard U/Th measurements using a MC-ICP-MS in addition to the common approach used for years.
