In the Makrana area, marble is found as five steeply-dipping bands. They form part of the Ajmer Formation of the Delhi Supergroup, which is a sequence of sedimentary rocks that was deposited in the Delhi Basin during the Proterozoic. About 1450 Ma these rocks were affected by the Delhi Orogeny, causing the metamorphism that transformed the original limestones to marble and the folding that caused the steep dip and the current outcrop pattern.
