Transcript of Minerals
By Princeton Luz
Minerals are classified according to their hardness
Minerals are solids found in nature .
They are inorganic, have ordered atomic structures and have definite chemical composition.
Rocks vs. Minerals
Collections of minerals and non-minerals
Do not necessarily have a definite chemical composition
Collection of elements and compounds
Have a definite chemical composition
PROPERTIES OF MINERALS
Color of Minerals
Color is a physical property sometimes used to identify minerals

What are minerals?
Gypson, Soapstone and Calcite
Apatite and Feldspar
Quarts and Topaz
– color of finely powdered mineral
– tested by scratching the mineral with a white tile
– the plane where the crystals break
– along the weakest area of the mineral’s structure
– form thin layers (mica) or shape called rhombohedron (diamond)
– If the mineral does not have a weak spot it breaks by itself (quartz and copper)
– the way light interacts with the surface of the mineral (adamantine-diamond, metallic-galena, greasy, silky, dull, pearly, waxy, or vitreous/glassy-quartz)
Fluorite has a range of colors.
– the flat faces of the crystal are of different shapes
