Marble
Marble is a metamorphic rock derived from limestone , existing in a variety of colors, which may have veins or (veins and colors are due to inclusions of metal oxides, most often).
Some types of marble are given specific names, such as cipolin or cherry. Some marbles, such as antique green, composed of limestone and serpentine , are ophicalces.
The word comes from Latin Marmor History Long, the antiquity ( Pliny ) in the eighteenth century , it was thought that the marble was a living material which, itself, the excavations replugged careers and all the rocks for the sculpture were improperly called marbles. In the Antiquity , the careers of Pentelicus , overlooking Athens from Paros , the Proconnesus in the Sea of Marmara or Aliki on Thasos are most important. Their products are even exported at that time and found the sarcophagi or elements of the marble statuary in most ancient Greek colonies of the Mediterranean basin. In Roman times the famous quarries of Carrara marble in Tuscany are beginning to be exploited. Also at this time that the extraction begins in the fields of the Alentejo region of central Portugal. Although discovered in the same period in Belgium , more precisely in Wallonia , the famous marble black Belgian royal red and not know that their glory days later with Golzinne or Dinant. In France , we extract the marble in the Pyrenees , northern France has some deposits operated either by stones or in aggregate. Is extracted also in Italy and France in the Alps marble quarries green (or serpentine), particularly in the Valle d'Aosta (quarries Verrayes ) and in the valley of the Ubaye (former career Maurin). Since the highest antiquity , the use of marble is related to art and to the will of men. It is indeed a rare material, heavy, fragile and precious that only the masters know how to work. "Invented" by the ancient Greeks and initially carved idols rigid funeral by Cycladic civilization , it is then used in solid blocks for prestigious architectural religious (statues of deities, temples, tombs) or political (stages). The Romans who share the passion for this material systematize research and develop techniques for extracting and processing. The marble was then part of the treasures that bring back the victorious generals of the newly conquered provinces as well as precious metals, spices and slaves. The aura of prestige, exclusivity and luxury no longer leave this matter which will be illustrated in the architectural and artistic achievements of the most significant in human history (the Acropolis , the city of Rome , the Church of St. Sophia (Constantinople) , the David of Michelangelo, the Versailles of Louis XIV, temples Jains and the Taj Mahal in India, the Arche de la Defense in Paris, the Parliament Palace in Bucharest , etc.). Some pieces of rare marbles contain inclusions of fossils , including great lumps of ammonites found in England . Marble has been used experimentally in the nineteenth century for the preservation of meat. Deposit
