摘要

An investigation along the coastal belt of South Tamil Nadu has revealed that the Karstic formation consists of sandy limestone beds interbedded with calcareous sandstone layers and parting of shales of Late Miocene age. Geomorphological observations through satellite data(Landsat 5 TM) in the scale of 1:50,000 helped to identify these zones sharply by their spectral reflectance. Stratigraphic column as recorded in different traverses reveals that the limestone ranges in thickness from 15 to 17 m and includes the remains of Pelecypodes, Gostropods and COral framgments. Coarse grains are associated with the limestone, presumably derived from the Archaean basement. In some places, Knakar surface has been developed due to weathering. A schematic geological profile was drawn depicting a clear alternate depression of clastics and carbonates.
