Marble is a metamorphic rock composed of recrystallized carbonate minerals most commonly calcite or dolomite marble is typically not foliated although there are exceptions in geology the term marble refers to metamorphosed limestone but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.

The following is a list of rock types recognized by geologists.
Then due to various conditions within the earth the existing rock was changed into a new kind of metamorphic rock.
As per wikipedia metamorphic rocks arise from the transformation of existing rock types in a process called metamorphism which means change in form the original rock protolith is subjected to heat temperatures greater than 150 to 200 c and pressure 1500 bars causing profound physical and or chemical change.
It is composed primarily of the mineral calcite caco 3 and usually contains other minerals such as clay minerals micas quartz pyrite iron oxides and graphite under the conditions of metamorphism the calcite in the limestone recrystallizes to form a rock that is.
