Geology and geochemistry of granitoid rocks in Panggong Lalat, Gua Musang, Kelantan

This research focussed on the geology and geochemistry of granitoid rocks in Panggong Lalat , Gua
Musang Kelantan. The objectives of the research are to produce the geological map of 1:25000 scales
of the study area, determined the petrography and geochemistry analysis of granitoid rock in
Panggong Lalat and to investigate the distribution of Rare Earth Elements (REE) with different
granite types in Panggong Lalat area. To achieve the objectives, few method have been applied such
as the geological mapping, petrography and geochemical analysis using XRF analysis and ICP-MS
analysis.The lithology of the study area was granite, well-bedded limestone and metamorphic rocks of
slate and they are included in the Permian toTriassic age. For the specification of the research study,
petrography and geochemistry analysis of granitoid rocks were also studied as there were lacks of
information regarding geochemistry analysis of granitoid rock in the study area. From the major and
trace elements from XRF analysis, granitoid classification of the study area was identify. Based on the
result, the study area are composed of I-type and A-type granite with IUGS classification of Phaneritic
Quartz Monzonitete for pink granite and Phaneritic Quartz Syenite for grey granite. The tectoning
settings for both pink and grey granite were determined from their trace elements and their granite
types as A-type granite was found in batholith zone while I-types granite’s tectonic setting was in
subduction zone. Panggong Lalat area show the highest distribution of Rare Earth Elements in Gua
Musang based on ICP-MS analysis as Light REE of La, Ce and Nd and Heavy REE distributions of
Gd and Y were highly obtained in the research area.
