Langkawi UNESCO Global Geopark is located in the far north-western corner of peninsular Malaysia. Located in the northern State of Kedah, it is unique in the sense that it was formed on 99 islands that together made up the legendary Langkawi Archipelago. The natural landscape of Langkawi is a combination between highly vegetated hills of rainforest and some rather barren rocks.
The Geopark has the best-exposed and most complete Palaeozoic sedimentary sequence in Malaysia, from the Cambrian to the Permian period. Langkawi UNESCO Global Geopark was part of Sibumasu Block. During Early Permian, the Sibumasu Block broke out from Gondwanaland, rifting northward and collided with the East Malaya-Indochina Block to form the Southeast Asian mainland. Later, during the Mesozoic, the islands underwent a major tectonic event that resulted in the emplacement of its numerous granitic rocks. At the same time, the entire Peninsular Malaysia was uplifted, including the Langkawi islands. Much of the geological development was somewhat linked to what had happened in the old supercontinent Pangea and southern hemispheric Gondwanaland since more than 550 million years ago. Langkawi UNESCO Global Geopark is the combined result of these various processes and the ongoing weathering process that has taken place since the Langkawi land was brought to the surface around 220 million years ago.
Geodiversity and biodiversity are preserved in Machinchang Cambrian Geoforest Park, Kilim Karst Geoforest Park and Dayang Bunting Marble Geoforest Park. These geoforest parks also protect biodiversity in diverse habitats including mangroves, tidal flats, beaches, estuaries, coral reefs, caves, limestone and many more harbours for various life forms.
