Stalagmite is one kind of
secondary carbonates formed in limestone caves (speleothem). After cave water
droplets containing Ca2+ and HCO3- drip onto floor, carbonate in the water
might become supersaturated due to CO2 degassing under certain conditions,
resulting in the formation of stalagmite in a process year after year.
Stalagmite is one of important geological archives for paleoclimate research.
The advantages include wide spatial distribution, suitable for U-Th and U-Pb
dating, enriched in climate proxies, continuity, long time span, comparability
and lower sampling cost etc. This database contain all published records which
can be applied by all related researchers.
