SPLT-NP

Speleothems are geologic formations, which commonly accumulate in caves. This material is made of a stalagmite from Spain. Speleothems are useful climate archives of our most recent past (10.000-500.000 years).

Carbonates

Trace element concentrations in (bio) carbonates are used as proxies in paleo-climate research (foraminifera, corals, pteropods, mussel shells, red algae, stalactites, etc.), serve as proof of origin (corals, otoliths), etc.
