What it is Filled

A coarse-grained intrusive igneous rock composed mainly of quartz, feldspar and mica, formed by slow cooling of magma deep in the crust; one of the most common rocks of the continents, quarried worldwide as dimension stone for buildings, monuments, kitchen worktops and paving, and named in the trade by quarry and colour.

Why it exists Filled

Let an agent identify granite and its varieties, explain its formation and properties, relay stone standards, quarrying and radon information from geological and industry sources, and separate true granite from other stones sold under the name.

Distinguishing features Filled

  • Coarse-grained plutonic rock
  • Quartz and feldspar dominant
  • Formed by slow cooling at depth
  • Trade name used loosely for hard stones

What robots and AI may and may not do Filled

Must not

  • Cut, grind or polish granite without the dust controls workplace rules require.
  • Present granite as free of radon emission without measurement.
  • Misrepresent the origin or type of a stone in sale.
  • Remove stone from protected landforms or heritage sites.

Only with a human decision

  • Opening or extending a quarry.

May

  • Identify granite from its texture and mineral content and describe its uses.
  • Report quarry, block and slab records for the operator.

Moral aspects Filled

  • Silica dust from cutting granite causes silicosis in workers.
  • Quarries change landscapes and lives of neighbouring communities.

Who is affected

  • Quarry and fabrication workers
  • Neighbours of quarries
  • Buyers of stone

Owners Filled

Steward

The landowner or quarry operator under a mining or planning permit.

What else AI and robots need to interact with it Filled

Identity and identifiers required Filled

  • Vercy registry: vr.tr.granite
  • Wikidata: Q41177 (https://www.wikidata.org/wiki/Q41177)

Direct properties required Filled

  • density: about 2.6-2.8 g per cubic centimetre
  • compressive strength: about 100-250 MPa
  • quartz content: about 20-60 percent - by definition

Recognition required Filled

  • Visible interlocking crystals
  • Quartz, feldspar and mica together
  • Gneiss is banded; basalt is fine-grained; many trade granites are other rocks
  • A speckled coarse-grained rock in grey, pink, white or red, with visible crystals of quartz, feldspar and mica.

Capabilities and actions required Filled

  • identify granite by minerals and texture
  • explain formation and properties
  • relay stone standards and testing
  • distinguish geological granite from trade granite

Hazards and failure modes required Filled

  • Silica dust exposure in quarrying and fabrication
  • Low-level radon emission from some granites
  • Cracking and staining in worktops
  • Misnaming other rocks as granite

Standards and interfaces required Filled

  • EN 12670 and related standards for natural stone terminology and testing
  • ASTM C615 for granite dimension stone
  • Quarrying and worker safety rules including silica dust limits

Context of use required Filled

  • Building and decorative stone; a common continental rock.
  • geological granite varieties by composition and texture
  • named commercial granites by quarry such as Baveno and Bianco Sardo
  • granitoids including granodiorite and tonalite
  • weathered and decorative forms
  • granite landforms such as tors and inselbergs

Sources Filled

  1. Wikidata item Q41177: granite - identity and sense of the item
  2. Wikipedia: Granite - general description of the item

Open questions

  • Should commercial granite names be separate entries?
  • How should stone standards be linked?
  • The registry entry has merged aliases naming quarry stones; should they be split off?
