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.
The present study is carried-out to have an idea about varying infiltration rates with varying soil types and cover in Kota Bharu-the capital of Kelantan state. The study area, covering a land area of about 394 km² lies between latitudes of 06˚10'N and longitude of 102˚20'E. Geologically, the area is mainly comprised of Quarternary alluvium having fluvial and marine origin which is constituted of mainly sand, gravel, silt and clay underlain by granite and metasedimentary rocks. The soil properties like texture, structure, water content, temperature and other factors like vegetation types and cover, and rainfall intensity play a significant role in controlling infiltration rate. Generally, coarse grained soils having large pore spaces with stable structure allows water from rainfall to enter unimpeded throughout a rainfall event. Otherwise, soils that have reduced infiltration may cause flooding in the area. From the soil classification map produced by Department of Agriculture (DOA), selected soils would be tested using double ring method to identify the infiltration rate in the study area. The method employed consists of two metal cylinders of diameter 30 cm and 60 cm that are driven partially into the soil. The ring is filled with specific level of water and the time at which water moves into the soil is measured, thus the rate of infiltration could be calculated in the field. An infiltration map will be produced at the end of the study which will be very useful for decision makers while dealing with flood management. The present study will be also very handy in agricultural field regarding the judicious and timely irrigation.
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.
Peninsular Malaysia is being distributed into three parallel belts (Western, Central and Eastern). Kelantan is one of the states in Peninsular Malaysia and consider as a unique territory to have all three belts (Western, Central and Eastern). Each belts divided into several formations which are Western Belt (Main Range Granite), Central Belt (Jeli Granite, Kemahang Granite, Noring Granite, Kenerong Leucogranite, Berangkat Tonalite and Senting Granite) and Eastern Belt (Boundary Range Granite). Rare Earth Elements (REEs) are usually concentrated related to the alkaline – peralkaline, carbonalite igneous rocks, as well as sedimentary rocks. Granitoid and some intrusive volcanic rocks are widely exposed in Malaysia, as well as Kelantan state. REEs are relatively abundant in the Earth crust, however these elements are rarely concentrated in the mineable ore deposit. There are a lot of research about granitoids, but very limited studies about the distribution of the REE. The objective of this study is to investigate the distribution of REEs in different type of granitoid rocks in Kelantan. For this purpose, 15 samples were selected and analysed using Inductive Coupled Plasma Mass Spectrometry (ICP-MS). Result shows that, distribution of light REEs in all samples up to 78% and heavy REE up to 22% with total value 5350.69 ppm and 1491.27 ppm respectively. Surprisingly, Jeli Granite formation (LT15) is high potential of REE among the samples tested with total REE 3164.93 ppm and Kemahang Granite (JD18) is least potential with total REE 31.95 ppm. The granitoid distribution can be found widely in Kelantan with special characteristic and detailed study about mineral composition will help identifying the REE potential as well as generate more relatable study about genesis and nature of rocks in Malaysia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
