This paper aims to provide the overview of occurrence, distribution and origin of the heavy minerals in the study area. A total of 45 selected stream sediment heavy mineral concentrate samples were panned using standard dulangs, dried and separated from other light minerals using bromoform. The heavy minerals were separated into different fractions at different amperes using Frantz Isodynamic magnetic separator. Mineral identification was done using binocular microscope augmented by X-ray diffraction analyses. Mineral abundance data were analysed graphically using triangular diagrams to show their origin. Dominant minerals present in the heavy mineral samples collected are ilmenite, cassiterite, tourmaline, zircon, topaz, and magnetite. The less common minerals, present in trace amounts are hematite, xenotime, allanite, monazite, rutile, anatase, leucoxene, chromite, garnet and olivine. Examination of the heavy mineral assemblage shows that they originated from granite batholiths of the Main Range, Changkat Rembian as well as from the metasedimentary rock in the area. The gold flakes present are found together with cassiterite and topaz indicating that gold originates from the mineralized veins contact-metamorphosed metasedimentary rocks. Almost all samples collected contain cassiterite grains in various amounts. From the mineral assemblage, the source of cassiterite originates from the mineralized quartz veins that cut granitic rocks of Main Range, Changkat Rembian as well as the metasedimentary rock in the area. Greisenized veins containing quartz, mica and tourmaline with the presence of wolframite and arsenopyrite also contribute to the presence of cassiterite in this study area.
