The proposed Kinabalu Geopark, in the district of Ranau, Sabah covers an area of approximately 1,000 KM2. The Kinabalu Park dominated by Mount Kinabalu (4,095.2M) with an area of 754 KM2 is the core of the proposed geopark. It has a very wide range of habitats, from rich tropical lowland and hill rainforest to tropical montane forest, to sub-alpine forest and scrub on the higher elevations. Its complex geology consists of the oldest rock in Sabah (Crystalline Basement), highly fractured and tectonised sedimentary and metamorphic rocks (Trusmadi and Wariu Formations), ophiolite suite (Chert-Spilite Formation and associated igneous rocks) and the Crocker Formation. 
The main batholith of Mount Kinabalu is composed of granodiorite. Uplifted ultrabasic rocks are also found in abundance. The Pinousok Gravels was deposited during the Pleistocene by glaciation process. Major topographical features include peaks and plateau, gullies, rivers, streams and waterfalls, hot springs, cave and granitic bodies.
Unique displays of the effects of past glacial activities in the shape of "nunataks" jagged peak (such as Low's Peak and South Peak), striations, grooves and polished surfaces, the creation of cirques, U-shaped valleys and gullies, roche mountonnes and deposit of glacial moraines are worth considering for conservation. The wide spectrum of rocks such as granite intrusive, basic and ultrabasic, volcanic, sedimentary and metamorphic rocks, will also compliment the conservation efforts in promoting the Kinabalu Park and its surrounding areas as a Geopark.
