Geology of Temangan and biogeochemical study of plant and soil in Malaysia

This research covered 25 km2 of area with latitude 5°38'16.8" N to 5°41' N and longitude 102°07'30" E to 102°10'12.4" E. This research was carried out due to the limitation of geological information in the area as there are only large-scale studies had been done. Also, biogeochemical study of plant and soil in Malaysia was conducted due to less research was done on biogeochemistry in tropical region. Thus, the objective of this research is to produce a geological map of Temangan area with scale 1:25,000 and to review the existing biogeochemistry study of element concentration in plant and soil samples in selected area in Malaysia based on previous research. The general geology of study area was determined by referring to articles from internet and past year undergraduate thesis. The thematic and geological maps were produced using ArcGIS software with the help of secondary data like DEM data from USGS website. The study area comprises five lithological units: schist, sandstone, shale, andesite and ignimbrite. The formation of geological structures are influenced by Lebir Fault. For biogeochemistry study, four articles in different areas in Malaysia were choose. Four parameters were discussed involving plant species and its morphology, soil and/or sediment properties, geological condition of the area and the elemental distribution of plant and soil samples. The relationship of geology and the geochemistry of soil and the relationship of the concentration of elements in plant and soil geochemistry were determined. Melastoma malabathricum in Bukit Besi, Terengganu and Antidesma montis-silam in Mount Silam Forest Reserve, Sabah shows a very high Al and Ni element concentration in plant sample. According to Reeves, et al. (2017), those two plants are recognized as Al and Ni hyperaccumulator plant species.
