Geology and granitoid geochemistry of Bandar Utama Gua Musang

The study area is located at Bandar Utama Gua Musang, Gua Musang, Kelantan with the dimensions of 25 Km2 of research area. This research paper is concerned with the objectives to produce the geological map of the research area with the scale of 1:25,000 and to analyze the petrography and geochemistry of the granitoid rocks in Bandar Utama Gua Musang for better understanding their petrogenesis. The geological information in the study area is collected through geological mapping process. The study area involved two formations which are Gua Musang Formation and Gunung Rabong Formation. Gua Musang Formation consists of meta sedimentary rock, volcanic tuff, limestone and granite whereas Rabong Formation consist of conglomerate. In addition, alluvium is the recent formation found at Galas River. All the findings and data are plotted in geological map. The structural analysis indicates that the principal stress or main compressive stress force ( ) is from the North-east and South-West direction. The geochemical analysis is done in four granitoid samples with code 18LALD1, 18LALD2, 18LALD3 and 18LALE15. The result shows that the granite in study area is Stype granite. LREE is dominant than HREE with Ce and Nd have the highest distribution value.
