The study conducted in the Aring area, with the latitude of 4° 51’ 00” N to 4° 58’ 17” N and longitude of 102° 19’ 24” E to 102° 24’ 40” E. Three geological formations existed in this area, namely the Aring Formation, Telong Formation and Koh Formation. The lithology of the Aring Formation includes volcanic rocks such as lapilli tuff, andesite, autobreccia. Other than volcanic, the Aring Formation also consists of limestone, sandstone, and shale. Roughly similar to Aring Formation, the Telong Formation in this area is comprised of Mudstone Unit I, which consists of mudstone, carbonaceous shale, sandstone and tuffaceous mudstone. Koh Formation, however, has quite distinguished lithology and only comprised of sedimentary rocks. The lithology includes conglomerate, sandstone, shale, chert and Mudstone Unit II; carbonaceous lime mudstone and mudstone. Six fossil phyla, namely Echinodermata, Brachiopoda, Cnidaria, Antropoda, Porifera, Mollusca and unidentified trace fossils, were observed in the study as strong evidence of the paleoenvironment of the Aring area. In terms of geoheritage, the fossil occurrences in Aring were determined as regionally significant and essential for that area’s regional geology. Fossil is not significant and rare or unique occurrences to classify the fossil occurrences as high rank for geoheritage value. The development of fossil sites over this area can be considered only for educational and scientific purposes. Although fossils were found to be diversely distributed in several locations at Aring, Gua Musang, Kelantan, the levels of significance and value of Total Heritage Value were not high enough to acknowledge the fossils in Aring as a geoheritage potential site.

The study is carried out in the northern Kelantan region, specifically at Batu Melintang, Jeli, across a distance of around 20 km2. The study’s main aim is to analyze groundwater potential that can be used for future mining or agricultural propose. Batu Melintang’s lithology consists of slate, phyllite, schist, hornfels, metasiltstone and metasandstone with granitic intrusions. Sungai Pergau and Sungai Tadoh are the major rivers in the area fed by tributary drainages located in the gold mining zones. It is crucial to assess the groundwater potential for future usage as any disruption of the watershed drainage system, could interfere with the primary surface river system which will eventually hinder the importance of Batu Melintang as a gaining popularity geotourism site. This research is conducted by using geological mapping and resistivity surveys. Four survey lines of 200 m are conducted within the study area using the Wenner configuration. Resistivity data is processed using Res2Dinv software and result with RMS error lower than 20% were produced. Both pseudosection of lines L1 and L2 show the occurrence of fresh groundwater (1-100ohm.m) at a depth of 5 meters and below the surface. It also shows the activity of normal faulting that might produce the aquifer. In the cases of LS3 and LS4, potential groundwater found in the continuous low angle aquifer located deeper around 10m to 30m might also be produced by the activity of the thrust fault. The study also found that the best groundwater potential occurred in the zone within the fractured bedrock of metamorphic rock.
