WHAT IS MARBLE?
Marble is recrystallization grains of calcite (limestone) or dolomite rock under high temperatures and pressures. This feature of marble differentiates character of the rock as a metamorphic rock when compared to sedimentary limestone rock.
The word ‘’marble’’ derives from the Greek marmaros, ‘’shining stone’’ (OED). This stem is also the basis for the English word ‘’marmoreal’’ meaning ‘’marble- like’’.The Marmoros word also gave the name to this island due to the marble coming from Marmara Island.
