The close association between the Gua Musang formation, Telong formation, Aring Formation, and Nilam marble reflect the lateral facies changes among these formations. Poorly delineated boundaries between each formation calls for a reassessment on the genetic and stratigraphic correlation of these formations. The newly proposed Gua Musang Group is defined as argillite-carbonate-volcanic deposited within the same Gua Musang platform during Permo-Triassic period, which includes all four formations under study. High resolution stratigraphy is needed for each formation for better stratigraphic correlation between the various lithostratigraphic units of the Gua Musang Group and other chronologically related rock formations in the region.The new division of formations within this Group is proposed based on lithologies and stratigraphic correlation that could provide better understanding on the geology of northern section of Central Belt of Peninsular Malaysia.

Breccia dominated rocks outcropping in the Tanjung Murau-Tanjung Sekakap area have been deposited in a composite system of alluvial fans and Gilbert-type deltas. The sedimentary facies ranges from boulder-dominated facies at the bottom to gravelstone-sandstone-dominated facies at the top of the succession. Other recognized facies are disorganized boulder-cobblesupported breccia (Bd), crudely stratified cobble-boulder-rich breccia (Bs), crudely stratified cobble-rich gravelstone (Gs-1), disorganized clast-supported gravelstone (Gd), crudely stratified pebble-rich gravelstone (Gs-2), normally-inversely-graded gravelstone (Gn-i), crossbedded gravelstone (Gc), stratified sandstone (Ss), massive sandstone (Sm) and homogenous mudstone (Mh) facies. Alluvial fan association feature discontinuous breccias and gravelstones (facies Bd and Bs), where sheet-floods and debris flows are dominant. The gravelstone dominated facies Gd, Gs-1 and Gs-2 intercalated with facies Gc are associated with the topset-foreset of a Gilbert-type fan-delta. The Gilbert-type topset are represented by facies Gc, Gn-i and Gs-2 as well as facies Ss. The dominance of breccia and gravelstone facies of alluvial fan and Gilbert-type topset-foreset delta facies associations suggest that these sediments were deposited on a steeply sloping continental margin with a rate of deposition similar to the rate of subsidence.

The theoretical understanding suggests that geotourism relates tourism and geology in such a way that the public can experience the earth’s geological wonders with environmental and cultural understanding, appreciation, and conservation through formal and informal education. With proper enforcement emplaced, this idea of protection through usage should lead to an increase in ecological and socio-cultural awareness and behaviour among geotourists and local guardians of geological heritage. In the prospect of geotourism, geotourists and local public are related in a way that the former play its part in geoheritage conservation through visiting geological heritages while expenditures spent by geotourists contributed to the gross income of the latter and partially to the nation through various tax structures. These economic benefit as well as environmental incentives of geotourism would encourage local public to embrace into geotourism industry and geoheritage conservation. Thus, when these mechanisms work perfectly, geotourism will offer one realistic key solution to the apparent conflict between environmental and cultural protection, and economic growth.

Several localities of Upper Permian brachiopod dominated shelly fauna have been discovered from the Merapoh area in northwest Pahang. The fauna consists of more than forty species offree living and pedunculate brachiopods, associated with other benthic elements such as bivalves, gastropods, fenestrate and stony bryozoans, solitary rugose corals, trilobites etc. Most of the fossils are preserved as moulds and casts, but they show very good biocoenosis assemblages. The brachiopods assemblages belong to the Upper Permian Leptodus Shale fauna which shows some similarities with other Upper Permian fauna from southern Tethyan region. Stratigraphically, the brachiopod fauna can be divided into two zones, the Oldhamina dicipens and the Haydenella minuta Zones, equivalent to the lower and middle Dorashamian (= Changshingian) Stages, respectively. The Leptodus Shale fauna is developed on shallow carbonate and volcanic high during a period of active volcanism. Abstrak: Beberapa lokaliti fauna cengkerang berusia Perm Akhir yang didominasi oleh brakiopod telah ditemui daripada kawasan Merapoh di baratlaut Pahang. Fauna ini mengandungi lebih daripada empat puluh spesies brakiopod yang hidup bebas serta yang melekat dengan pedikel. Fauna ini berasosiasi dengan unsur-unsur bentos lain seperti bivalvia, gastropod, briozoa fenestrat dan briozoa membatu, karang rugosa tunggal, trilobit dan lain-lain. Kebanyakan fosil terawet sebagai acuan dan kas, tetapi fosH-fosH ini menunjukkan himpunan biosinosis yang baik. Himpunan brakiopod ini kepunyaan fauna syal Leptodus berusia Perm Akhir yang menunjukkan beberapa persamaan dengan fauna berusia Perm Akhir dari daerah Tethys selatan yang lain. Secara stratigrafi, fauna brakiopod ini dapat dibahagi kepada dua zon, iaitu Zon Oldhamina dicipens dan Zon Haydenella minuta, setara dengan Tahap Dorashamian (= Changshingian) awal dan tengah. Fauna syal Leptodus ini terbentuk di atas karbonat dan volkanik yang cetek ketika volkanisme agak aktif.
