"Geological Survey of India officials have brought to government's notice the importance of the formation of these cliffs and the need for conserving them," he said while replying to a submission of Varkala Kahar (Cong).
The government's objective was to declare the area a heritage site and get it named in UNESCO's heritage list, Chandy said.
Varkala, about 51 km from here, is the only place in South Kerala where cliffs are found adjacent to the Arabian Sea.
These tertiary sedimentary formation cliffs are a unique geological feature on the otherwise flat Kerala coast.
Cliffs are considered a geological monument and this particular one is termed by geologists as 'Varkala formation'.
