KANDUNGAN UNSUR TANAH JARANG DI PERAIRAN KAMPAR, RIAU
Abstract
The paper describes distribution and rare earth element contents in surface and sub surface sediments of Kuala Kampar waters area. To find out the distribution of rare earth element in the study area, forty-five samples have been analysed. According to REE analysis the sediments in Kuala Kampar area consist of Thantalum (Ta), Neobium (Nb), Zirconium (Zr) and Ytrium (Y). Zirconium found in all samples of surficial sea bottom sediment. Zirconium content ranged between 2,8 ppm and130 ppm. On the other hand subsurface seabottom sediment from core data shows zirconium content between 20,1 ppm and 75 ppm. Ytrium found in all samples analysed and the content range between 4,1 ppm and 39,3 ppm, while from core data ytrium content between 8,6 ppm and 17 ppm. Neobium found in thirtythree samples chemically analysed, the content range between 0,06 ppm and 15,3 ppm, where the highest content occur in MKP-69. From the core neobium found.in BH-2 core data (11 m - 12m) 5,5 ppm and BH-3 the content range between 2,6 ppm and 6,9 ppm. Thantalum found in 23 samples and the content range between 1,43 ppm and 19,30 ppm, where the highest content occur in MKP-69. From the core (BH-1, BH-2 and BH-3) thantalum is not found Most of Rare earth element generally found in sea bottom sediment: sand, silty sand and sandy silt.
