Speleothem is the general term for any secondary mineral deposit formed in a cave.
Here's a breakdown:
* Speleothem: The overarching category for cave formations.
* Stalagmite: A speleothem that rises from the floor of a cave, formed by dripping water depositing minerals.
* Stalagtite: A speleothem that hangs from the ceiling of a cave, also formed by dripping water depositing minerals.
So, while there is no specific scientific name for stalagmites, they are classified under the broader category of speleothems.
