Abstract
Rock Type: Igneoues
Province: Crocker Province
Age: Middle Miocene – Pliocene (13.82 – 2.58 million years ago)
Origin: CPSB Cengyap Quarry & CPSB Kapa Quarry, Sabah
* This is a unique rock that accommodated the highest mountain in Southeast Asia, Mount Kinabalu.
It is known as granodiorite, a type of igneous rock (parent: granite) form from felsic (white-light coloured magma) during intrusion of the magma from the mantle.
* Dating of the rock from has shown youngest age of the magma intrusion may take place between 8-9 Ma, although some of the other samples show slightly older age. This indicate the emplacement of Mt. Kinabalu is episodic and alternated by pulse emplacement (Cottam et.al. 2010).
* The minerals of the rock consist of large crystals of quartz, plagioclase and potassium feldspar, and hornblende.
* Quartz in this rock is easy to spot because of its grey colour and looks like glass.
