The session highlights the latest developments in the understanding of the sedimentology, petrography, isotopic and elemental composition, fluid inclusion composition, and growth dynamics of speleothems. It explores their relation with environmental and climatic proxies. Their integrated study leads to a better interpretation of time-series and provides chronologically well-constrained information on past climates and environments, rainwater composition, human occupation and specific events. Monitoring of the cave environment and study of the vadose zone above the speleothem site, as well as simple models of deposition processes or of surface-cave-speleothem transfer processes, are often crucial to robust interpretation of speleothem data. This session welcomes all studies from monitoring, modelling, and analysis of speleothems that advance our capacity to make paleoenvironmental reconstructions from speleothems. It also welcomes newest records or information retrieved from speleothems.
