Petrographic Analysis of Bentong-Raub Suture Rock Types in Batu Melintang, Kelantan

Abstract

The study focuses on the petrographic analysis of rock types in Batu Melintang area, which is part of the Bentong-Raub Suture Zone. The Bentong-Raub Suture Zone is genetically related to the sediment-hosted or orogenic gold deposits associated with the major lineaments of the Central Gold Belt of Peninsular Malaysia. Based on the conducted petrographic analysis, it showed the rock types of Bentong-Raub Suture identified in Batu Melintang, Kelantan; included schist, slate, phyllite, gneiss, hornfels, marble and granite. Most of the rocks showed a preferred orientation of rock minerals that indicated they undergo regional metamorphism. The petrographic analysis was conducted by analysing the thin section to measure the amount of mineral content in the rock sample. The thin section produced from the petrographic analysis gives information on the type of rocks in the study area as it gives confirmation of the rock types and also acts as supporting data to produce an updated geological map.
