Abstract
The study utilises a range of analytical techniques, including petrography,
SEM-EDX, XRD, XRF, and ICP-MS, to examine the metasedimentary host rocks and
patterns of mineralization. The results indicate that the tin deposit is linked to
metasedimentary rocks, specifically slate, that have seen regional metamorphism. The
main valuable mineral found in the ore is cassiterite, which is associated by pyrite. The
host rocks are classed as pelites, which are generated from the continental crust in a
Continental Island Arc context. The hydrothermal alteration zones that have been
identified consist of propylitic, potassic, argillic, and sericitic zones, each of which is
distinguished by unique combinations of minerals. The research findings indicate that
the Air Putih tin deposit is the outcome of intricate geological processes encompassing
metamorphism and hydrothermal activity. The study suggests conducting additional
comprehensive geological mapping, alteration mapping, and geochronology studies to
gain a deeper understanding of the deposit's properties. This knowledge can then be
combined with information from other tin deposits in the Eastern Belt of Peninsular
Malaysia. This study makes a valuable contribution to the possible revival of
Malaysia's tin mining industry and establishes a foundation for future exploration and
research in the area.
