Are Marble Formed From Limestone. Limestone forms when shells sand and mud are deposited at the bottom of oceans and lakes and over time solidify into rock. Limestone used for centuries in the construction of door window sills headers and water tables to protect the building as well as garner its natural beauty. Siding sills water table with limestone.
The resulting marble rock is typically composed of an interlocking mosaic of carbonate crystals. During metamorphism the calcite limestone recrystallizes forming the interlocking calcite crystals that make up the marble.
Hence limestone gives birth to marble when transformed.
Marble on the other hand is a rock formed when limestone recrystallizes into marble during the mountain building process. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. During metamorphism this calcite recrystallizes and the texture of the rock changes. Before metamorphism the calcite in the limestone is often in the form of lithified fossil material and biological debris.
