Adam's bridge is not man made-Reports
Tuticorin: Adam’s Bridge is only a formation of discontinued sand islands/formations running about 27 km between Dhanushkodi and Talaimannar.Making a passage for Sethusamudram project by destroying a part of it will not create any geological imbalance in the region.This was stated in a paper titled ‘Scientific understanding of Adam’s Bridge’ published by N. Ramanujam, professor and Head, Post Graduate Department of Geology and Research Centre, V.O.Chidambaram College, Tuticorin, a few days ago.The paper throws light on the origin and the evolution of the Adam’s Bridge, right from the tectonic and ‘paleogeographic’ events recorded in sequences in the Cauvery basin, which eventually led to its creation.Dr. Ramanujam says that the Adam’s Bridge is nothing but deposits formed by the extension of foreland spits of long shore currents from the both sides of Dhanushkodi and Talaimannar. According to him, three studies conducted by the Geological Survey of India in 2003, two on Dhanushkodi land mass and one on the nearest of the 18 sand formations from Dhanushkodi which constitutes the Adam’s Bridge, clearly substantiated the continuum of the sedimentation pattern in the region.
“A study of sand samples determined the age of Adam’s Bridge as 20,000 years, not 17.5 lakh years as believed in a section of society,” he says.The alignment chosen for the construction of the project was ideal, as the choice of other alignments which came up for deliberations during the preliminary stages of discussions would have disturbed the coral reef eco system in the Gulf of Mannar region, he adds.
