General geology and characterization of clay in Gua Musang, Kelantan

The study area is located in Gua Musang, Kelantan within 4°47'55.92"N, 101°54'12.21"E coordinates. This 5x5km2 study is surrounded by plantation like palm plantation and rubber plantation and heavy forest. The lowest elevation of the study area is 95m while the highest is 491m. The study focuses on the general geology to produce a geological map at a scale 1:25000 and characterization of clay properties of Pulai for industrial purpose. The geological mapping was conducted to collect the data to determine the geology of the area and some from previous research. There are three types of lithology found which are limestone, sandstone, and shale. For geological mapping, go to field for traversing and collecting the data, then produce the map using GIS software. In this study, X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF) and Scanning Electron Microscopy (SEM) is used in the sample analysis to determine mineralogy and elemental composition clay in the study area. The XRF analysis revealed SiO2, Al2O3 and K2O as the major element while the other element shows in minor quantities. Element in all samples in XRD analysis ranges from 30% to 36% for Si, 8% to 12% for Al, and 5% to 6% for K. In the thin section AIN11 mineral feldspar is present which it can be weathered by chemical weathering to form clay minerals. AIN1 also present mineral feldspar in SEM EDS shows mineral anorthoclase and albite with same element but different in percentage.
