Petrography of the main range granite characterization in Titiwangsa rest stop, Perak, Malaysia

The Main Range Granite intrudes the country rock which includes metamorphic rocks during the Triassic period after the merging of two continental plates. The rock in the focused region entirely consists of plutonic rocks which are biotite granite and metamorphic rocks. Those metamorphic rocks include gneiss and mica-schist. The area of interest is in the middle between the Titiwangsa Rest Stop, Perak dispensed along the longitudes and latitudes of five°36'34.39"N to 5°35'31.74"N and 101°29'59.52"E to 101°35'20.08"E with roughly 25km2 in terms of surface area. This paper introduces petrography onto finding biotite granite that interfered and intruded metamorphic rocks based on the observations on the rock’s mineral surfaces. Geographical mapping procedure was utilized to observe the selected region and the rock samples were gathered from outcrops that can be detected around the area as well. In view of the petrography analysis, the hand sample of the biotite granite shows phaneritic and holocrystalline surfaces. The biotite granite is coarse-grained and shows an exceptionally minor of alkali feldspar as phenocryst. The minerals that comprise in the biotite granite are overwhelmed with alkali feldspar, with normal rate of plagioclase and quartz, while biotite is more dominant in the rock contrasted with hornblende. The focused region extends from the Titiwangsa Rest Stop towards the Gerik-Jeli highway is found straightforwardly on the Bentong-Raub suture zone.
