Abstract
Rock Type: Igneous Rock - Granite
Province: Main Range Province
Age: Late Triassic (230 - 200 million years ago)
Origin: Tampin, Negeri Sembilan
* These featured rock is called biotite granite originated from Tampin, Negeri Sembilan, was formed in Late Triassic Period approximately 230 - 200 million years ago.
* Biotite granite refers to a type of granite that contains the mineral biotite as one of its primary components. Granite is an intrusive igneous rock composed mainly of quartz, feldspar, and mica, with biotite being one of the common types of mica found in granite.
* Biotite is a dark-colored mineral belonging to the mica group. It typically has a dark brown to black color and can impart a darker hue to the granite in which it is present. The presence of biotite gives the granite a characteristic speckled appearance.
* It forms through the cooling and solidification of molten magma deep within the Earth's crust. As the magma cools, minerals such as quartz, feldspar, and dark-colored biotite crystallize, creating the distinctive speckled appearance of the granite. The slow cooling process allows for the development of coarse-grained textures in the rock
