Minerals and stones in Italy

  1. 1. THE EURORAINBOW OF SCHOOLS GREECE 18-23 MARCH 2012 STONES AND MINERAL RESOURCES IN SICILY
  2. 2. MINERAL RESOURCES IN SICILY • Central Sicily is famous worldwide for its mines of sulfur and splendid specimens, still unmatched in the world for their beauty, of sulfur, celestite and gypsum. • In the ‘700 development of the chemical industry in France and England with great demand for sulfuric acid for the production of soda, increased the demands of sulfur, stimulating research and the opening of new mines. It was used in medicine but also in the gunpowder weapons industry.
  3. 3. SULPHUR
  4. 4. Sicily is also famous for some zeolite to be found in the western part of the island • Zeolite is a strange material. If you spray water on it begins to radiate heat up to 80 degrees, then dry out and quickly return to the initial position, ready to heat up again. No wonder her name means "boiling stone".
  5. 5. CELESTITE • Celestite (or celestite) is a mineral consisting essentially of strontium sulphate (SrSO 4)is located in the limestone soils and sediments associated with gypsum, anhydrite, halite and sulfur. • It is s extracted to obtain strontium carbonate which is used as special glass screens for televisions and monitors.
  6. 6. GYPSUM
  7. 7. • Gypsum is a typical mineral which is formed by direct precipitation from supersaturated waters. • Gypsum, milled and dried, is used in construction, sculpture, stationery and, in the noble varieties of colored alabaster, as a decorative stone
  8. 8. OBSIDIAN • Obsidian is an igneous rock that is generated due to the rapid cooling of magma brought to the surface by volcanic eruptions. It is used to make necklaces and precious weapon points.
  9. 9. ROCK SALT
  10. 10. PUMICE STONE • Pumice is an igneous explosive rock,very light for the very high porosity. It is the only rock that floats in water. It is used in cosmetics (known as pumice stone) and in the industrial laundry (stone wash). The building industry uses it as an acoustic and thermal insulation
