Petrography of The Main Range Granite Characterization in Titiwangsa Rest Stop, Perak, Malaysia

Abstract

The area of research is located in between the Titiwangsa Rest Stop, Perak allocated along the Gerik-Jeli highway, approximately 25km in area. The objective of this research is to remodify a geological map with a scale of 1:25,000 and to determine the petrological aspects of the metamorphic mineral assemblages around the study area. One of the methods used during the initial of this research is primarily on previous research and literature review. The geological mapping technique such as traversing was applied to map the allocated study area and rock samples are collected from three different outcrops that are exposed around the area as well. Moreover, the samples are then sent to a lab to undergo microscopic and petrographic analysis of the rocks’ compositions by producing thin sections to determine the mineral assemblages which surround the area on Titiwangsa Rest Stop, Perak. The rocks that can be identified around the area include igneous and metamorphic rocks such as biotite granite, gneiss, and mica-schist. The area of research which extends from the Titiwangsa Rest Stop towards the Gerik-Jeli highway is located directly on the Bentong-Raub suture zone. The depositional setting hypothesized in the area is a marine depositional coastal environment which includes a transition of a lower grade metamorphic rock towards a higher-grade metamorphic rock.
