  • 1. What is Natural Stone? BASIS OF STONE FORMATION• Sedimentary• Metamorphic• Igneous 1
  • 2. What is Natural Stone? SEDIMENTARY FORMATION 2
  • 3. What is Natural Stone? METAMORPHIC FORMATION 3
  • 4. What is Natural Stone? IGNEOUS FORMATION 4
  • 5. What is Natural Stone? STONE SPECIES Sedimentary Metamorphic Igneous Limestone MarbleCalcareous Travertine Serpentine Onyx SlateSiliceous Sandstone Granite Quartzite 5
  • 6. Natural Stone Types CALCAREOUS SEDIMENTARY: LIMESTONE• A sedimentary rock consisting chiefly of the mineral calcite, (CaCO3) with or without magnesium carbonate• Dolomite – Calcium Magnesium Carbonate CaMg(CO3) 2 6
  • 7. Natural Stone TypesCALCAREOUS SEDIMENTARY: LIMESTONE 7
  • 8. Natural Stone Types CALCAREOUS SEDIMENTARY: TRAVERTINE• A finely crystalline, massive deposit of calcium carbonate, of white, tan, or cream color, formed by chemical precipitation from solution in surface and ground waters, as around the mouth of springs, especially hot springs 8
  • 9. Natural Stone TypesCALCAREOUS SEDIMENTARY: TRAVERTINE 9
  • 10. Natural Stone Types CALCAREOUS SEDIMENTARY: ONYX• A compact, cryptocrystalline, and generally translucent variety of calcite, usually deposited in cold water solutions, often in the form of stalagmites and stalactites in caves 10
  • 11. Natural Stone Types CALCAREOUS SEDIMENTARY: ONYX 11
  • 12. Natural Stone Types CALCAREOUS METAMORPHIC: MARBLE• A metamorphic rock consisting of fine to coarse-grained re-crystallized calcite and/or dolomite• Varying levels of soundness – A, B, C, D (Ref: MIA Design Manual) 12
  • 13. Natural Stone Types CALCAREOUS METAMORPHIC: MARBLE 13
  • 14. Natural Stone Types CALCAREOUS METAMORPHIC: SERPENTINE• A rock group made up principally of the mineral serpentine (Mg, Fe)3Si2O5(OH)4. Serpentines have a greasy or silky luster, a slightly soapy feel, and a tough, conchoidal fracture; they are usually compact but may be granular or fibrous and are commonly a green or greenish gray. 14
  • 15. Natural Stone TypesCALCAREOUS METAMORPHIC: SERPENTINE 15
  • 16. Natural Stone Types SILICEOUS SEDIMENTARY: SANDSTONE• A classic sedimentary rock composed of grains of sand size (1/16 mm to 2 mm ø) set in a matrix of silt or clay and united by a cementing material, commonly silica, iron oxide, or calcium carbonate- the sand particles are commonly quartz 16
  • 17. Natural Stone Types SILICEOUS SEDIMENTARY: SANDSTONE 17
  • 18. Natural Stone Types SILICEOUS METAMORPHIC:SLATE• A compact, microcrystalline metamorphic rock, usually formed from shale deposits 18
  • 19. Natural Stone Types SILICEOUS METAMORPHIC: SLATE 19
  • 20. Natural Stone Types SILICEOUS METAMORPHIC: QUARTZITE• A metamorphic rock consisting mainly of quartz, formed by recrystallization of sandstone by regional or thermal metamorphism 20
  • 21. Natural Stone Types SILICEOUS METAMORPHIC: QUARTZITE 21
  • 22. Natural Stone Types SILICEOUS IGNEOUS:GRANITE• Geological Definition: A plutonic rock in which quartz makes up 10 to 50 per cent of the felsic components, and the alkali feldspar to total feldspar ratio is between 65 and 90 per cent• Commercially: Any holocrystalline quartz- bearing plutonic rock 22
  • 23. Natural Stone Types SILICEOUS IGNEOUS: GRANITE 23
