The Speleothem collection has been made up by Sophie Verheyden. It contains speleothems from Belgian and foreign caves. Several speleothems are already dated. The collection has the goal to use the sampled material in an optimal way in order to avoid duplicate sampling in caves. Speleothems are used at RBINS to reconstruct ancient climate and environments. More information on each speleothem is available in the DaRWIN database.
