Investigation Of Potential Weathered Ree-Bearing Granitoid Crust From Dinding District Of Western Tin Belt, Peninsular Malaysia

This research interpreted a green and sustainable exploration strategy of ion-adsorption type REE clay potential deposits with minimum or free radioactive issues in some prone districts of western Peninsula Malaysia. An intensive characterizationstudy was conducted on two sets of samples from Dindin...

Mechanics of materials This research interpreted a green and sustainable exploration strategy of ion-adsorption type REE clay potential deposits with minimum or free radioactive issues in some prone districts of western Peninsula Malaysia.

Petrographical study and geochemical analysis showed granitoids in Lumut (LU) and Telok Murok (TM) sites were ilmenite-series, mainly peraluminous, S-type which were classified into syeno-granite and monzo-granite, respectively with k-feldspar, quartz, plagioclase and mica group as major minerals.

In both sites, depletion of REE+Y (REY) content in horizon A was considerably apparent, whilst REY enriched in horizon B and/or C. The maximum content of REY could be as high as 3500 ppm in horizon B2 and /or C analyzed by ICP-MS. Total REE content (TRE) of the weathered crust is relatively elevated compared to the parent rocks (3 to 7 times), in horizon B and C of both sites.
