Tálchyr Beds

Tálchyr Beds, a group of strata occurring at the base of the Gondwana series of India. They probably occupy the same geological horizon as the Permian System of Europe, but owing to the rarity or absence of marine fossils their exact correlation with their European equivalents is somewhat uncertain. The beds are remarkable for the occurrence in them of numerous small and large erratics, some of the latter measuring 15 feet in diameter. In the neighbourhood of the Godavari the included blocks of foreign and transported rocks are smoothed, polished, and striated in the same manner as glaciated stones. Moreover, the hard Vindhyan limestone which underlies this Tálchyr boulder-bed is similarly smoothed and scored in long parallel lines.
