Physical volcanic features associated with lava tube, channels, tunnels and effusive centers have been utilized by the ancient artisans for creating some of the magnificent geoheritage sites in the Deccan region of Western India. This region is covered by thick, black, dull luster basalt units with inherent presence of cooling cracks, iron and ferromagnesian minerals. It shatters during chiseling and accelerated weathering gives permanent brownish stains. Thermal baking and induration in zones close to lava tubes, channels, tunnels and effusive centers, has hardened the rocks, sealed the cracks, amalgamated iron and ferromagnesian minerals and attained vibrant shades of red to become suitable for excavations and sculpturing. Remnants of lava tubes and channels, composed of thermally baked, indurated and reddened basalt were recognized as an excellent rock for carving the statues and idols as well as exceptional dimension stone. Degree of baking and induration gets reduced with increasing distance and is also utilized in deciding sculpturing pattern. Hollow cylindrical tubes emptied by draining out of lava in high gradient areas, were found suitable for innumerable cave temples. Saptashrungi temple, at the portal of lava tube; Sita Mata cave, Nasik; Bhartahari Cave, Ujjain; Pataleshwar and Baneshwar temples, Pune; are examples of lava tunnels. Innumerable generations with different religious beliefs, such as Buddhists and Hindus, have worked in tandems for centuries to create Ajanta, Ellora, Elephanta, Kanehri, Karla, Bhaja cave complexes; in favorable regions. Frequent attacks by invaders were resisted; however, large-scale destruction in several cave complexes were repaired by the matching baked and indurated rocks.
