Editing Varkala (section)

==Geology==
Varkala is an important place as far as geology is concerned as it exposes sedimentary rocks belonging to the Cenozoic age, popularly known in the geological literature as the Warkalli formation. The Warkalli formation, along with the Quilon formation, represent sediments laid down in the Kerala basin that existed during Mio-pliocene times. The Quilon formation of the Miocene age is made up of limestone, and the Warkalli formation is made up of alternating beds of sand and shale exposed along the Varkala cliffs. Thin seams of lignite in the shale of the Warkalli formation suggest good vegetation at the time of deposition of the clay sediments.{{cn|date=July 2023}}
