A batch of twenty zircon megacrysts (0.5–1.5 cm3) from Sri Lanka was studied. Within-grain rare earth element (REE) compositions are largely homogeneous, albeit with some variation seen betweenAt present approximately 40,000 tons ilmenite, 25000 tons rutile and 1200 tons zircon are produced. In the international market they fetch $240, $1700 and $ 1900 per ton respectively. We now have 565 workers in our factory. To keep them occupied we need 240,000 metric tons of sand to get these minerals.Ilmenite Mining in Sri Lanka Destructive of the Environment?

U-Pb ages of detrital zircon and monazite from beach placers in Sri
Sri Lanka is a Precambrian terrane with high-grade metamorphic rocks that form four major lithotectonic units based on Nd isotopic mapping and zircon U-Pb dating: the Highland (HC), the Wanni (WC), the Vijayan (VC), and the Kadugannawa (KC) complexes (Fig. 1) (Milisenda et al., 1988, Kröner et al., 1991, Cooray, 1994).The HC in Sri Lanka’s largest mineral sand deposit occurs in Pulmoddai, and the surrounding area of the mineral sand deposit has been identified as a high natural background radiation area. The food crops grown in the area are used for human consumption. However, the long-term consumption of high radioactive foodstuff may Annual committed effective dosage from natural radionuclides

U-Pb geochronology of zircons from river sediments in Sri Lanka
Geochronology of zircons from river-sediments in Sri Lanka has never been attempted. Here we present Rare Earth Elements (REE) and U-Pb isotopes of ∼700 zircon grains by laser ablation ICP-MS technique, from sediments of the major rivers in the Sri Lankan basement (rivers of Mahaweli, Kelani, Kalu, Walawe, Maduru Oya and Maha Oya).Zircon Concentrate Production: Zircon mineral concentrates are produced by mining heavy mineral sands from land- and marine-based deposits. Australia, South Africa, China, Indonesia, Mozambique, India, Ukraine, Sri Lanka, Madagascar, Brazil, Kenya and several other countries were producing zircon concentrates in 2014.
