Geology and demarcation of potential aquifer zone in karstic terrain using surface geological mapping in Kuala Nerus area, Gua Musang, Kelantan

The study took place in Kuala Nerus, Gua Musang and its surrounding area. The study area consists of carbonate rocks, metamorphic rocks, sedimentary rocks and volcanic rocks that are under the Gua Musang Formation. The focus of the research is to produce an updated geological map of the study area with the scale of 1: 25 000 and to identify any potential aquifer zone in a karstic terrain within the study area. In order to do so, method such as geological mapping and geomorphological investigation are conducted. This method involves field visits, sample collecting and data analysis such as joint and fracture analysis. In determining a karst aquifer, geomorphological data analysis such as sinkhole, cave, joint and other conduits that can lead to the transportation of water to the earth in or near a karstic terrain are conducted. Laboratory work such as using the petro-thin for petrography purpose also involved. Result of this research is the finding of three aquifer zone in Kuala Nerus area, Gua Musang. All three aquifer are different from each other in term of the size, surrounding lithology and geomorphology resulting in the finding of three different karst aquifer that can hold different amount of water. So this research determine which aquifer has the most potential to be utilized. This result will help in the future research.
