oh, i feel gneiss..

granite formation on Pulau Tepur, Langkawi


layers in sandstone

The fact that langkawi given geopark status as reported today is very much welcomed. After the Tg Balau magnificent structural formation is known as one of the Geological Heritage Sites in Malaysia, this recognition is never too late. Geologist/geology students in Malaysia or from South-East Asia, ( if not the world) have long branded Singa Formation and Machincang Formation as a must stop for outcrop lovers.
Geological sites have not only remnants (rocks, rocks and rocks). Take a closer look, and you would see communities of sponges, bivalves ( the humble, oyster, calm-like), gastropods ( that's like your modern looking snail), and yes,humongous lizard, etc. But of course, outcrops like the famous Morrison Fm, A'insa Fm have been in the limelight since years ago. Give a chance to our local 'lipatan and nendatan', kekar, ricih, batu kapur berfosil dan batu pasir berstratifikasi (jenuh nak ingat the 'local' term, are they correct?) to make the headlines.

Next time you are in Langkawi, stop by these formation/geoparks and have your photos taken there. Bear in mind that in the background, you have there, rocks (geologically) that were formed billion years ago. As for the formations in Langkawi, they are one of the oldest, dated back to Cambrian (eg: Machincang Formation is the eldest in Asia). Singa Formation (mudstone, silstone, ), Setul Formation - a limestone , with some secondary sandstone and shale. Another limestone formation is the Chuping Formation, which is also the youngest among the four formations.
For those in Johor, another attraction for geological park, is the Tanjung Balau area. It has a resort nearby, with a small nelayan community. (On a lighter note, 1 minggu di Tg Balau, aktiviti mandi laut di waktu petang itu musti selepas seharian 'berjemur' di atas batu-batan).
