This study aims to map rocks variation and geological features and identifying the geodiversity values for geotourism potential in Pergau area. Generally Pergau area is dominated by granitoid body from Noring Granite and Kenerong Leucogranite. Based on the field observation, there are five (5) variation of granites; 1) the coarse grained dominant with quartz and feldspar, 2) fine grained, 3) pink megacryst biotite granite, 4) coarse grained dominant with hornblend, and 5) foliated granite. The assesment of geoheritage values show that Pergau is basically a little too low values to be as geotourism site and the level of significance is only local to state. However, the scientific and education values are higher, which ressemble that Pergau area is very important for the research and educational site.

Renyok River has many unique and interesting geosites. So far there are very few academic publications related to Renyok River so that its potential as a tourist area is not discovered. In order to ensure the Renyok River geosite has the potential to be developed as a tourist attraction, a comprehensive geomorphosite study is carried out along the Renyok river. In this study the data collection was carried out through geomorphological mapping on geosite along the river. Geomorphosite data were obtained and analyzed in reference to the standard values created by Kubalikova. River landform dominated by leucogranite and metasediment where contacts can be found in many locations. The analysis shows that the Renyok River geomorphosite value is quite high in all aspects assessed including Scientific and Intrinsic aspects (75%), educational (87.5%), conservation aspects (62.5%), and value added aspects (75%), but low value only in economy aspects (33%). Overall conclusion is that the Renyok River has a high potential to be developed as a geotourism area with a note that all deficiencies will be improved in the future and subsequently could be beneficial to economic strengthening.

This study aims to interpret the seismic facies and geological structures of the Miocene-Pleistocene succession based on the 3-D seismic dataset. The seismic data was interpreted by using Kingdom 8.8 version software. The dimension of study area is approximately 187 km2 (14.8 km long by 12.6 km wide). The variable types of seismic facies and geological structures were determined from the horizontal (inline) and vertical (crossline) lines in 2D seismic section of study area. The seismic facies can be classified into for major seismic facies such as parallel and sub-parallel, wavy, facies that reach out to south-east and chaotic reflector. Parallel and semi- parallel facies consist from high amplitude to low amplitude and moderate to high continuity. The mounded discontinuous seismic facies also can be seen in the seismic section and can be interpreted as turbidities depositional environment at the two-way time (TWT) ranges from 1.4 to 1.5 ms. The chaotic facies contain natural gas as it display due to an error to a wave at the two-way time ranges from 1.0 to 1.1 ms. The geological structures were determined at the study area consists of anticlines, syncline and faults that can be interpreted as structural and stratigraphic trap for potential hydrocarbon.

Generally, the Temburong formation was observed for both research studies and hydrocarbon exploration. There was few research conducted on its lithostratigraphy and micropaleontological purposes in terms of research studies. However, there is no evidence suggested to observe the paleoenvironment condition of the formation based on the calcareous nannofossils occurrences. Therefore, this research was performed deliberately to identify paleoclimate prediction of Batu Luang, Klias Peninsular based on the assemblages of the calcareous nannofossils. 17 samples have been collected from a measuring section of a cutting hill along the road. Simple smear preparation was used and observed their assemblages were under the light microscope. As many as 27 species have been identified and dominantly preserved by discoasters and sphenolithus. Thus, this formation has been considered an oligotrophic condition and low latitude region due to the distribution of warm-water taxas. Plus, less contribution of cold-water taxa Coccolitus pelagicus to the formation is late Oligocene to early Miocene.
