speleothem
Let an agent identify speleothem types, explain how they form and what they record, relay conservation and cave access rules, and separate speleothems from other cave features and from mineral deposits outside caves.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

What it is Filled
A mineral deposit formed in a cave by the precipitation of minerals from dripping, flowing or pooled water, most often calcium carbonate: stalactites, stalagmites, columns, flowstone, draperies, rimstone dams, helictites, cave pearls and coralloids; speleothems grow slowly, record past climate in their layers, and are protected in many caves.
Why it exists Filled
Let an agent identify speleothem types, explain how they form and what they record, relay conservation and cave access rules, and separate speleothems from other cave features and from mineral deposits outside caves.
Distinguishing features Filled
- Secondary mineral deposits in caves
- Shape follows water movement
- Layered growth recording climate
- Fragile and slow to regrow
What robots and AI may and may not do Derived, awaiting review
May
- identify types from form and setting
- explain formation and growth rates
- explain their use as climate archives
- relay conservation and access rules
Note: Affordances listed as what may be done; prohibitions collected from the text.

Recognition required Filled
- Formed by mineral precipitation in caves
- Types by shape: stalactite, stalagmite, flowstone, helictite, pearl

- Contamination of climate records by poor sampling
Standards and interfaces required Filled
- Cave protection laws and national park rules

Context of use required Filled
- Not for anything; natural cave formations, valued for science and beauty.
- dripstone: stalactites, stalagmites and columns
- flowstone and draperies
- rimstone dams and pools
- helictites and anemolites
- cave pearls and coralloids
- shields and moonmilk

Open questions
- Should each speleothem type be a separate entry?
- How should cave protection law be linked by country?
- The registry entry has merged aliases naming specific types; should they be split off?
- Which entry fits the mineral?
- Which entry fits karst processes?
- Which entry fits palaeoclimatology?
