Geology and rock coatings as a record of climate changes of Kampung Kalai, Jeli

The research mainly focused on the geology and study on rock coatings as record of climate changes. The study area of this research is located at district of Kelantan which is small town in Jeli called Kampung Kalai. Kampung Kalai is located at 05° 46' 54.12" N and 05° 44' 5.07" N latitude and 101° 43' 42.76" E and 101° 46' 30.47" E longitude that covers about 25km2. The lithology, geomorphology, structural geology and the geological setting of Kampung Kalai, was studied. This study aims to update geological map of Kampung Kalai in scale 1:25000, to study on rock coatings in term of petrographic analysis, microscopic image, and shape. The petrographic analysis supported with the thin section is conducted to determine the type of rock and its formation. For geochemistry analysis, the sample rock and soil was collected at 14 different places and the coordinate recorded. Soil analysis is used to analyses the composition of oxides by using X-Ray Fluorescence (XRF). There are 5 types of coatings have been identified which are case hardening, iron film, dust film, lithobiontic coating, and rock varnish. Elemental analysis and scanning electron microscopy (SEM) were used to analyse the microscopic image of rock coating with these rock coatings. SEM analysis, petrographic and XRF analysis showed evidence that rock coating can record climate change by geochemical analysis. This study provided an updated geological map and the geochemistry analysis that can give the information about the role of the rock coating as a record of climate changes
