LICHENOMETRIC DATING CURVE AS APPLIED TO GLACIER RETREAT STUDIES IN THE HIMALAYAS.

The study critically favours the importance of lichens in estimating palaeoclimatic events and its use in depicting the future discretion regarding glacier retreat. Besides the various lichenometric studies carried out in Indian Himalayan region, the world-wide classical work of different glaciologist and geologist on different applications of lichenometry is also well focused. The study also highlights the benefits, restrains, and drawbacks associated with the lichenometry. Being a globally accepted biological technique particular emphasis is given on the need of innovative approach in implementation of lichenometry in Indian Himalayan region.
