Sea water high in magnesium flows through porous limestone and replaces some of the calcium with magnesium turning limestone into dolostone.

Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism.
Unlike terrestrial materials meteorites have a crust formed by the high heat generated by atmospheric friction and they usually look blacker than surrounding rocks.
In the formation of marble metamorphism causes variable recrystallization of the original carbonate mineral grains which results in interlocking mosaic of carbonate crystals.
