Geology and geochemical prospecting for heavy mineral of Kg. Kalai and Kg. Tadoh, Jeli, Kelantan

The study area is located at Kg. Kalai and Kg. Tadoh. The objective of this research is to study the general geology of Kg. Kalai and Kg. Tadoh included the geomorphology, lithology, stratigraphy and structural geology. The other objectives are to identify the potential presence of heavy minerals such as silver (Ag), copper (Cu), lead (Pb) and iron (Fe) in the stream sediment of Sg. Tadoh, and also to produce the geology and geochemistry maps of Kg. Kalai and Kg. Tadoh. Based on Malaysian and Thai Working Groups (2006), they have stated that Kg. Kalai area is underlain by metasedimentary rocks, which are close to the granite intrusion. Besides that, H.E. Hawkes (1957) has defined geochemical prospecting for minerals as any method of mineral exploration based on systematic measurement of one or more chemical properties of a naturally occurring material. Based on the geological mapping that has been done at Kg. Kalai and Kg. Tadoh, the lithologies found are marble, phyllite and granite. Marble is the most abundant rocks found in the study area. This metamorphic rock is included in Mangga Layer which is in Permian age and it is the oldest rock in the study area. The lithology, stratigraphy, geomorphology and structural geology found during the research were mapped in the maps in the thesis. For geochemical prospecting of heavy minerals, eight stream sediment samples were collected at the confluence points of Sg. Tadoh and the samples were analyzed for the potential presence of heavy minerals such as silver (Ag), copper (Cu), lead (Pb) and iron (Fe) using AAS method. The results of the geochemical analysis were thereafter subjected to statistical analysis. The statistical plot shows that the dominant major element in the stream sediment is lead (Pb). The conclusion drawn from the geochemical analyses revealed that the high concentration (in ppm) of lead (Pb) is originated from the weathering of .the parent rock which is metamorphic rock. Thus, the parent rock can certified the lithology that was mapped on the geological map from Minerals and Geosciences Department (JMG). The result also indicates that the parent rock from which the stream sediments originated is contained lead-bearing minerals. The geochemical map of the study area was produced in the thesis.
