In the Northern Apennine mount areas of Italy , approximately the metropolis of Florence inward Tuscany , a rare variety of limestone is flora called “pietra paesina” or “Florentine marble”. The natural veins of impurities inside the stone convey arranged themselves inward shapes that resemble mountainous landscapes , castles , as well as ruins. For this argue , the stone is every bit good known past times diverse names such every bit “landscape stone” , “ruin marble” as well as “ruiniform marble.”

The immense trace per unit of measurement area created past times the crusade of the earth’s crust fractured the limestone. The fractures inward the stone were afterward filled past times atomic break 26 as well as manganese hydroxide deposited past times H2O percolating through the fragmented rocks creating the beautiful natural patterns. The cracks were later sealed past times the deposition of calcite crystals. This lawsuit is idea to convey occurred some fifty 1000000 years ago.
