This paper presented new study on the mineral assemblages and the compositions on the rocks protolith. Banding island and its surrounding area are dominated by low-grade regional metamorphism which located within the East Malaya Block and dated from Ordovician to Permian age. The study area is situated at longitudes of 101° 22’ 25”E to 101° 22 35”E and latitudes at 5° 33’ 47”N to 5° 32’ 95”N. The metamorphic rocks consist of phyllite, mica schist, and metasandstone interbedded with slate. Majority of the phyllite are highly weathered with visible joint. Phyllite in the study area contains quartz veins with thickness varies from 0.5 cm to 6 cm, that follows the direction of rock foliation. Phyllite is dominated with mica group with major muscovite mineral, and the mica is mostly muscovite. While the mica shist is also dominated with mica group with muscovite mineral. The intensity of the regional metamorphism is lowest from the west of the Banding Island to slightly moderate metamorphism toward the east of the study area, which supported by the changes of the metamorphic rock type from phyllite to schist according to the petrographic analysis. Regionally, Perak state especially in Gerik area are dominated by rocks from Paleozoic era as Perak is located in Western Belt of Peninsular Malaysia.

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.
