What it is Filled
A dark, fine-grained volcanic rock formed from rapidly cooled low-silica basaltic lava, the most common rock in the Earth s crust and ocean floor, rich in iron and magnesium minerals, with forms the registry aliases name such as mid-ocean ridge basalt, flood basalt covering vast areas, leucite basalt and named regional basalts, and the trade term bluestone; basalt forms lava flows, columnar joints as at the Giant s Causeway, and much of the seafloor, and it is quarried for aggregate and building stone. Some basalt dusts and fibres raise occupational health considerations.
Why it exists Filled
Let an agent explain basalt, relay formation, composition, forms and uses from geology sources, describe the named forms, and distinguish basalt from granite, gabbro as its intrusive equivalent, andesite and other volcanic rocks.
Distinguishing features Filled
- Dark and fine-grained
- Low silica
- Forms seafloor and columns
- Iron and magnesium rich
What robots and AI may and may not do Filled
Must not
- Recommend cutting or grinding basalt without dust control.
- Encourage collecting from protected geological sites.
- Misrepresent the origin of stone sold to customers.
- Direct people onto unstable basalt cliffs or columns.
Only with a human decision
- Quarrying or removing rock from protected sites.
May
- Describe basalt's formation, types and uses.
- Identify basalt from geological maps and samples, with uncertainty stated.
Moral aspects Filled
- Stone dust harms workers' lungs.
- Basalt formations are often protected landscapes and sacred places.
Who is affected
- Quarry and stone workers
- Visitors
- Local communities
Owners Filled
Steward
The owner of the land where it lies; geological surveys map it.
