Repository of stones used in Delhi and Agra UNESCO Sites

A comprehensive analysis reveals that the construction of five UNESCO World Heritage Sites in Delhi and Agra relies predominantly on three Precambrian age rocks: marble, sandstone, and quartzite. These sites include Qutb Minar and its Monuments, Humayun’s Tomb, Red Fort Complex, Agra Fort, and Taj Mahal. The study identifies the geological origins of these stones, tracing them to the Aravalli Mountain Belt (AMB) and Vindhyan Ridge, which are divided into three stratigraphic units: Delhi Supergroup, Aravalli Supergroup, and Banded Gneissic Complex. The topography of Delhi is significantly influenced by Alwar Group quartzites exposed in the Delhi ridge, small hills, and plateau, alongside Quaternary alluvium. This research provides a detailed repository of stones used in these heritage sites, offering insights into their geological context and architectural significance.
