popular geoconservation areas in Langkawi Geopark

The beauty of kilim lies in diverse dramatic karstic landscapes and landfroms. It is located at the eastern part of the Langkawi Island.

Various shapes and form of hills, island and pinnacles and dissolution of the Setul limestone. Dissolution usually begins along weaker zones such as joints, faults and bedding planes. Among the key landform features in Kilim are isolated and sparsely vegetated limestone hills with very few surface streams. Such dramatic features are remnant of ingoing dissolution, processes. Sometimes, dissolution of the limestone result in limestone pinnacles. These pinnacles can also be left standing as stacks in the sea after prolonged erosion. Coastal landforms are also dramatic, with cliffs dropping vertically into the water. Some of these cliifs   dropping vertically into the water. Some of these cliffs have been and carved into sea notches and sea arches by wave actions.

 

Underground karst landforms of kilim

exhibit some very well developed subterranean drainage systems as a product of prolonged dissolution processes upon the Setul limestone. Basically, acidic, rain water seeps into narrow cracks within the limestone beds and dissolve cavities along fault and point plane. As these features enlarge, they join together to form big chambers or mazes of passageways.

Gua kelawar

Gua kelawar

Gua kelawar located in the heart of kilim mangrove swamps within the Kisp Forest Reserve. The cave ios about 60 M long and was named as such because it support hundred of bats. Gua Kelawar consists of two caves.

The western cave has a floor area of about 270m2  with a low roof (1-3 m) trending northeast . The second cave bigger, having a floor area of about 750m2 , with roof reaching 10 m high trending north-northwest.

Interesting features and structures in these caves include stalactites, stalagmites, and fallen rock blocks. The most interesting and important feature is the occurrence of old shells , encrusting on the cave wall and roof. Radiocarbon dating indicated that the shell is about 5000 years old.

The altitude of the shell cluster shows that the sea-level at that time was about 2 m higher than the present.

Pulau Anak Tikus

Pulau Anak Tikus

Pulau anak tikus is a remnant island located at the southernmost tip of Langgun Island. This remnant island is made of dark colored, moderate to thickly layered limestone  representing the Early Ordovician Lower Limestone Member of The setul Formation.

This Limestone is very rich in fossils, particularly gastropod and cephalopod. Among most common gastropod are Malayaspira regosa, Teichispira Kobayashii, Helicotoma jonesi , Palaemphalus giganteus, Lesuerilla zonata and Hormota sp.

This island was formed as a result of prolonged erosion and solution along weaker zone on the neck of an ancient headland.

Fossil Island, or Pulau Anak Tikus is an island which is part of the Kilim Geopark. If you take a boat tour to explore the nature park, this island will be one of the amazing geosites you are likely to visit. The boat is parked at a small jetty of the island that leads to a flight of stairs. The surrounding water area is marvelous. You will see several other islands at a distance.

Gua cherita

Gua cherita

Gua Cherita was located offshore and at the northern water area of Langkawi. There was a legend said that many years ago Prince Rome and Princess of China about to get married however strongly disagree by Garuda (the phoenix and the eagle of Lord Vishnu). Garuda felt that with unification of two major powers of the world may cause huge problems for the smaller kingdoms, which would soon get swallowed by this combined power. Garuda then kidnapped Princess of China and kept her hostage in a cave. The legend is reinforced with existence of a strange stone formation which looks like a sleeping princess in the cave.

There are also old Arabic script inscriptions on the walls of the lower chamber of the caves. They are hardly visible these days. But they do exist. It is anticipated that some of the scripts relate to the verses of Koran and some relate to Sheikh Baharuddin. They are believed to be written in the year 1754 during the time of Sultan Mohamed Jiwa II of Kedah.

Gua Langsir

Gua Langsir

Gua Langsir located at Selat Peluru, opposite Pulau Langgun. This cave is a cave forming limestone. The cave is at an altitude of about 91 meters above sea level. This limestone is very rich in fossils and one can easily find fossils at this site. Gua Langsir is formed when stalactite and stalagmite are merged into a large pole in front of the cave entrance as like curtains that covered the door. There are a small underground tunnel which connects the sea and the lake at the other side of the cave. The lake is a dale filled by saline water and surrounded by vertical limestone cliff. One platform has been built towards the middle of this lake so people can enjoy the beauty of 360 views and the beauty of the flora and fauna found around this cave.

Tasik Langgun

Tasik Langgun

Tasik Langgun occurs within the Lower Limestone Member of The Setul Formation. It is the second largest freshwater lake in Langkawi which is formed due to the collapse of the embedded hole or vale which occurs when the water dissolves the limestone walls. The hole that embedded are common when there are limestones, carbonate rocks, or slat beds below the land surface which are naturally dissolved rock become too big, and without support for the land above, there would be a sudden collapse creating a sinkhole. In this time this will be filled with the rain water creating a typical lake.

Teluk Mempelam

Teluk Mempelam

Teluk Mempelam located on the northwestern coast of Pulau Langgun is the location of the Setul Formation rock form. It is the most famous exposure of Devonian rocks in Peninsular Malaysia. The changes from the Lower Limestone Member to the overlying Lower Detrital Members reflect the continuous rising of ancient sea level that allowed the deposition of fine-grained siliceous rocks and chert overlying the limestone and sandstone. The type section of the Upper Limestone Member is also located here and was deposited during the subsequent drop of the sea-level. Cephalopods, conodonts, and gastropods are dominant fossil in the Lower Limestone Member, trilobite and graptolite dominate the Lower Detrital Member, while trilobites, cephalopods, crinoids and trace fossils are the most common fossils in the Upper Limestone Member. The Upper Detrital Member is generally lacking in fossil. The prolonged erosion has resulted in the formation of broad erosion platforms at various ancient sea levels with several beautiful sea-stacks.

Gua Buaya

Gua Buaya

Situated off the Kilim River, Gua Buaya is uniques because it is actually a natural tunnel developed in the limestone by an underground stream that once flowed in this area during the low sea-level. Now the tunnel turns into a beautiful cave. The river flowed right through the arched cave and at low tide, a small boat can navigate from one side through to the other.

Inside the cave, there is an ascending chamber flanked by walls of limestone with minimal stalactites and stalagmites. Small colonies of bats roots on the ceiling of this cave. One can also observe ancient shells sticking on the wall and roof of this cave.

Teluk China Mati , Tanjung Dendang

Teluk China Mati , Tanjung Dendang

Teluk China Mati is unique for its ancient sea level indicator. Samples of encrusted Saccostrea cuccullata or rock oyster, indicated an age of around 7000 years old. This suggested that most of the present coastal area of Langkawi archipelago was submerged about 7000 years ago. Rock oyster can grow up to 20 cm long and very common throughout the Indo-Pacific, Eastern Atlantic and the Mediterranean. It is a bottom-dweller marine bivalve living at a depth range of about 0-5 m.

Pulau Tanjung Dendang is located in northeast of the Langkawi main island with north-south alignment. The island is composed of the Setul Formation. The northern part consists of the Middle Ordovician limestone and the southern part comprises the Lower Silurian limestone. The two limestone members are separated by th Lower Silurian Detrital Member. The rocks are well-exposed at Teluk China Mati.
