What it is Filled
A clastic sedimentary rock composed mainly of sand-sized grains of quartz, feldspar and rock fragments cemented by silica, calcite or iron oxides, formed from deposits in rivers, deserts, beaches and seas, varying in colour from white and yellow to red and brown, and widely quarried as a building stone in named varieties such as Jacobsville sandstone, Warthau sandstone, Schmerikon sandstone, Reigate stone, Florentine pietra serena and the brownstone of New York; sandstone hosts groundwater and hydrocarbons and weathers into distinctive landscapes.
Why it exists Filled
Let an agent explain sandstone and its formation, relay classification, properties and named building stones from geological and heritage sources, describe uses and weathering, and distinguish sandstone from other sedimentary rocks.
Distinguishing features Filled
- Sand-sized grains
- Cement type variation
- Porosity
- Building stone tradition
What robots and AI may and may not do Filled
Must not
- Recommend dry cutting or grinding sandstone without dust control and respiratory protection.
- Advise cleaning or repairing historic sandstone with methods that damage it, without a conservator.
- Encourage removing stone from protected outcrops or monuments.
- Misidentify the source of building stone in heritage records.
Only with a human decision
- Any intervention on a listed sandstone building or monument.
May
- Describe how sandstone forms and how named varieties differ.
- Assess the condition of sandstone buildings from survey data for their owner.
- Distinguish sandstone from quartzite and siltstone.
Moral aspects Filled
- Silica dust from cutting sandstone causes silicosis in workers.
- Sandstone heritage buildings are irreplaceable and easily harmed by bad repairs.
Who is affected
- Stonemasons and quarry workers
- Owners of historic buildings
- Future generations
Owners Filled
Steward
The landowner holds the stone; quarries are licensed and heritage authorities protect listed buildings.

What else AI and robots need to interact with it Filled
Identity and identifiers required Filled
- Vercy registry: vr.tr.sandstone
- Wikidata: Q13085 (https://www.wikidata.org/wiki/Q13085)
Direct properties required Filled
- grain size: 0.0625-2 mm
- porosity: about 5-30 percent
- compressive strength: about 20-170 MPa - varies
Recognition required Filled
- Cemented sand-grain rock
- Quartz arenite, arkose, greywacke; named building sandstones
- Siltstone and shale are finer; conglomerate is coarser; quartzite is metamorphosed sandstone
- A granular rock of cemented sand grains, often layered and coloured by iron.
Capabilities and actions required Filled
- explain formation and classification
- relay properties and named stones
- describe uses and weathering
- distinguish from other rocks
Hazards and failure modes required Filled
- Weathering and salt damage of buildings
- Silicosis from cutting
- Confusing sandstone with quartzite or siltstone
Standards and interfaces required Filled
- Building stone testing standards such as EN 12440 and ASTM C616
- Quarrying and heritage regulations
- Silica dust exposure rules
Context of use required Filled
- Building stone, aquifers and reservoirs.
- quartz arenite
- arkose
- greywacke
- lithic sandstone
- named building sandstones such as Jacobsville, Warthau, Schmerikon, Reigate stone, pietra serena and brownstone
- sandstone aquifers and reservoirs
Sources Filled
- Wikidata item Q13085: sandstone - identity and sense of the item
- Wikipedia: Sandstone - general description of the item
Open questions
- Should arkose and greywacke be separate entries?
- How should geological references be linked?
- The registry entry has merged aliases naming specific quarry stones; should they be split off?
