Geology of Subong Area, Gua Musang and petrology of its granitoid rock

Geological mapping of 25 km2 with the scale of 1:25000 were conducted in the Subong area, Gua Musang, Kelantan, Malaysia. Geographically, this area located at between 4°56’ 7.63” to 4° 58’ 48.69” North latitude and 101°55’ 3097” to 101° 57’ 47.33” East longitude.The objectives of the research are to produce an updated geological map and specifically the petrology of granitoid in the Subong area. Unit lithology in the research area can be divided into three main units. Description sequentially from the oldest to the youngest lithology units are as follows Slate Unit, Limestone Unit, Granite Unit and Alluvium Unit. The study area is part of Gua Musang Formation with age ranging from Permian to Quartenary. The geomorphology of the study area, Subong area can be divided into two units of morphology which is medium and low relief morphology unit. In the study area, the main geological structures that occurred in the area such as lineament features, joint structure and fold structure. For the study of granitoid rock, two granite samples were analyzed from the result of X-ray Flourescence (XRF) Spectrometry analysis and Inductively Coupled Plasma Mass Spectometry (ICP-MS). The grantoid that is found in the study area is classified as granodiorite. It is classified as I-type and shows a metaluminous characteristics as the value of A/CNK is less than 1.
