28 Dec Teris of Southern Tamil Nadu: A Saga of Holocene Climate Change: Thrivikramji et. al, 2008
The ubiquitous Teri deposits (extent=500 km2) or red sands of semiarid-southerncoastal- Tamil Nadu, chiefly noticed to occur in the Kattabomman and Chidambaranar districts, show unique shades of red ranging from yellowish red (5YR4.5/6) to dark reddish brown (2.5YR ¾) and dark red (10R 3/6). In aerial photos teris manifest in various morphological types, among which the commonest forms are sand dunes (shaped into barchans, barchanoids, and longitudinal dunes), interdune sand sheets, sandy hummocks and sand sheets. Besides, teris can grouped into ITDs (inland teri deposits, area= 33.0 km2) and CTDs (coastal teri deposits, area = 437.0 km2).
