Marble is a metamorphic rock. It is formed from the metamorphism (recrystallization) of limestone or dolomite rock.
From Ftmmachinery's passage about marble facts (blog/what-is-marble-rock.html), I know:
- Under the intense heat and pressure deep within the Earth's crust, the minerals in the limestone or dolomite undergo a process of transformation, resulting in the formation of marble.
- This process causes the original minerals to recrystallize, creating the characteristic crystalline structure and unique patterns and colors found in marble.
