Study Notes
Physical Properties of Minerals
- Minerals can be identified by their physical properties such as color, shininess, hardness, relative importance, taste, smell, and magnetism.
Chemical Properties of Minerals
- Chemical properties like reaction with acid and radioactivity also help in identifying minerals.
Common Minerals in Construction Materials
- Sand and stones used for construction are mainly composed of quartz and feldspar, which are tough minerals.
- Mica is also found in sand, and it is a relatively soft mineral.
Occurrence of Precious Gemstones
- Precious gemstones are found in combination with quartz and other elements in certain parts of the world.
Minerals Found in Mines
- Minerals like coal, silver, platinum, and copper are found in mines.
Diamonds
- Diamonds are found in the rocks of dormant volcanoes.
- Diamond is the hardest substance found naturally.
