The monazite placers of Sri Lanka are among the world's most thorium rich sediments. This study of the stream sediments and rocks from an area in the southwest of Sri Lanka shows that the highly ...
Pulmoddai is a town situated on the northeastern coast of Sri Lanka, close to Trincomalee. Pulmoddai lies between Trincomalee and Mullaitivu. It is famous for mineral sands that are mined at its beach. The Pulmoddai deposit is about 6 kilometers in length and about 100 meters in width. It is estimated to contain 6 million tonnes of heavy sand ...
Morphology and land use pattern. The Kalpitiya peninsula (Fig. 1) is a compound structure like a beckoning finger in the North-western coast of Sri Lanka.Morphologically it is a low-lying flat sandy terrain characterized by wide beaches, sand ridges and runnels, saline pools and dune formations.
