The Langkawi Geopark, comprising all of the
99 islands in the Langkawi archipelago
is Malaysia’s first geopark. It is located
in the northwestern corner of peninsular
Malaysia within the State of Kedah. The
total land area of Langkawi Geopark is about
478 square kilometres.
The main island is accessible by sea
from Kuala Perlis ,
Kuala Kedah and Penang or by air from
Kuala Lumpur, Penang and Singapore.
Identified as
the 'birthplace' or fetus land of the
region, the terrain and natural landscape
reflect the geo-diversity of the islands
that is deeply entrenched within the complex
geological history of the area. Langkawi
Geopark has the best-exposed and most
complete Palaeozoic sedimentary sequence in
Malaysia originating from the beginning of
the Cambrian to the Permian period. Later,
during the Mesozoic era, the islands
underwent a major tectonic even that
resulted in the emplacement of its numerous
granitic igneous bodies. This incredible
power generated by nature from deep beneath
the earth's mantle had pushed up huge blocks
of older rocks and placed them above a very
much younger terrain.
In Langkawi
geological history, much of the development
is linked to events that occurred during the
time of the prehistoric supercontinent
of Pangaea and the southern hemispheric
Gondwanaland
more than 550 million years ago. It probably
began with the deposition of the Machinchang
sandstone in a lacustrine environment during
much of the Cambrian time. This was followed
by the submergence of the land during the
late Cambrian period (~500m.y.), which saw
the invasion of shallow marine fauna into
the seas around Langkawi. The continuous
subsidence of the sea floor resulted in the
formation of thick limestone of what is
known as the Setul Formation during the
Ordovician period ( `440m.y.), at the end of
which the sea became too deep, causing
the limestone deposition to cease.
The Setul limestone continued to develop
from the Silurian until the Middle Devonian
( ~370 m.y.) period, followed by the
deposition of sandstone and mudstone -
an occurrence that is related to the
rafted ice during the melting of the
Gondwana ice cap.
The Chuping
limestone is believed to have stopped
depositing before the end of the Permian era
(~245 m.y.) by this tectonic event that
among others had brought up a large block of
earth crust in the eastern part of Langkawi
and overlapping the much younger block in
the west. The tectonic event ended with the
emplacement of granite beneath the Langkawi
crust at the end of the Triassic (`220 m.y.)
era. The black sandstone and mudstone of the
Singa Formation evolved during the early
Permian era (~280 m.y), before the sea level
was slowly brought up by a complicated
tectonic process.
What we have
in Langkawi today are the combined results of
these processes. The prolonged weathering
that took place ever since the land mass of
Langkawi was brought to the surface
around 220 million years ago has produced a
beautiful mountainous range of Machinchang
sandstone at the northwestern corner, the
conical Gunung Raya granite at the center
and a rugged terrain of Setul limestone in
the east. In the southwest, the Singa
Formation dominates, while the Chuping
limestone found itself in the western part
of Pulau Dayang Bunting. Some of the
landscapes are truly outstanding,
particularly those of the Machinchang and
the karstic limestone in the eastern part of
Langkawi.
Based on its outstanding geological
landscape and other associated features such
as the sedimentary structures, fossils and
erosional effects, Langkawi certainly is
geological heritage of high value.The
Langkawi islands are mainly protected under
the jurisdiction of the Permanent Forest
Reserves, Recreational Forest or Geoforest
Park that are overseered by the Forestry
Department.
THE
MACHINCHANG CAMBRIAN GEOFOREST PARK
The Machinchang Cambrian Geoforest Park
hosts the oldest geological formation in
Malaysia known as the Machinchang Formation.
Among the important geosites in the park are
Teluk Datai (where the oldest deposits of sand
rest), Pantai Tengkorak (where the old
continent had been submerged – exhibiting
fine examples of sedimentary structures).
Tanjung Buta / Pulau Jemuruk (graveyards of
the oldest life forms in the country) and
Tanjung Sabung (where the limestone succeeds
sandstone).
Also located
within the park are some natural wonders
that had resulted from recent geological
processes such as the Temurun and Telaga
Tujuh Waterfalls, remnant islands of Anak
Burau and Anak Datai and the beautiful
beaches in Teluk Datai and Pantai Kok. The Machinchang peak exhibits peculiarly chopped
sandstone that has often been associated
with the colourful folk myth of the brawl
between the two giants, Mat Chinchang
and Mat Raya . The Machinchang ridges can be
classified as one of the most beautiful
landscapes in the area.
KILIM
KARST GEOFOREST PARK
The Kilim Geoforest Park features limestone
dominating the eastern part of the main
Langkawi Island and the adjacent small
islands of the Setul Formation.
Magnificently formed landscape of nearly
vertical to subrounded karstic hills
with pinnacles of various shapes and sizes,
can be viewed.
The northeast region of Langkawi, which
comprises the three river basins of Kilim,
Air Hangat, Kisap and the neigbouring
island of Langgun and Tanjung Dendang are
spectacular in its beauty. The birds and the
cave system found in this area have also
contributed to the myths and legends of the
islands. The name ‘Langkawi’ is said to have
been derived from the Brahminy Kite eagle,
the most dominant faunal species in the
area. Gua Cerita (Cave of Stories),
which lies in the northern tip of the region
has many legends and beliefs associated with
the giant mythological bird, Garuda. The
epic battle between Rama and Rawana and Sang
Gedembai – a human-like giant female
creature with a power to curse anything and
turning it into stone.
Within these Geoforest Parks, caves are
plentiful for exploration activities,
while a collapsed cave has formed two of the
biggest fresh water lakes, namely Tasik Langgun and Pulau Dayang Bunting. Among the
caves found in the parks include Gua Tok
Jangkit, Gua Teluk Dedap, Gua Cerita, Gua
Teluk Udang , Gua Siam, Gua Buaya, Gua
Tanjung Dendang and Gua Kelawar.
The ecosystems of the old limestone rock
formation, the caves, the mudflats and the
seas that surround it have three main
vegetation: the mangroves, the vegetation of
the limestone hills and the flora of the
mudlats and beaches.
A mangrove forest promotes a unique root
system with a physiology of the plant
species that are capable of preventing soil
erosion and cleaning the water contaminated
with metallic pollutants. The mangrove also
serve as breeding grounds to many species
of fishes, prawn and other sea life. The
mangrove vegetation in this area is quite
diverse and includes many important species;
some with medicinal properties. The
limestone hills of the area have a rich
diversity of species of ornamental plants
such as the cycads and orchids, the
limestone rocks also support many bryophytic
flora, lichens and macro fungi.
Forty-five species of birds have so far been
recorded in the respective areas and this list
includes ten migratory species. The most
prominent among the raptor species found
along the sea coast and the river of the
northeast region are the Brahminy Kite and
white-bellied sea eagle. The two raptor
species are among the more popular
attractions. Other examples of biodiversity
that exist on the mudflats, the beaches and
the sea are mudskippers and
phytoplankton. A total of seven species of
mudskippers have been identified and 129 species of
marine and 55 of freshwater phytoplanktons recorded.
Bats are among the faunal species prominent in the area.
Three species that roost on the walls of
the well known Gua Kelawar (Cave of the
Bats) have been identified . The limestone forests are also
home to myriads of small and tiny faunal
species, of which the beetles have attracted
special interest. Many species were
collected from the forest of the Pulau
Tanjung Dendang, Pulau Langgun and Gua
Cerita and one of them is the smallest
beetle in the world, collected in Pulau
Tanjung Dendang. Some of these beetle
species are rare, some yet to be identified.
The Langkawi archipelago is rich in fossils
of ancient and extinct sea creatures from
the Paleozoic era spanning between 542
million years and 257 million years ago.
Several species of brachiopod were found and
identified. Among the fossils found are
those of a
280 million year-old brachiopod, which is also known
as lamp shells, and 400 million year old fossils
of scypho crinites in Teluk Mempelam on Pulau Langgun.
An alien granite dropstone that is at least 1 billion
years old can be found in a sandstone and
mudstone rock formation in Pulau Tepor
southwest of Langkawi. It is the oldest dropstone ever found in the region. This
dropstone once drifted along in a glacier
before it was dropped in Langkawi hundreds of million years ago.
Another geological treasure in Langkawi
comes in the form of ancient seabed located
in Pulau Ular.
DAYANG BUNTING GEOFOREST PARK
The Dayang Bunting Marble Geoforest Park
mainly comprises the Permian overthrusted by the older
Setul Formation limestones. These finest
marbles resulted from the baking of Chuping
Limestone by small granite intrusion
underneath. There are a number of caves
within the park. One of the most unique
features of the park is the Tasik Dayang
Bunting, a fresh water lake.
A large mangrove forest flourish along the
Selat Dayang Bunting ( Dayang Bunting
Straits) . The combination of landscapes
from marble and granite bedrocks formed a
figure resembling a pregnant woman on her
back,hence, the name Tasik Dayang Bunting or
Lake of the Pregnant Maiden.
