The Leptodus Shales of central Peninsular Malaysia: distribution, age and palaeobiogeographical affinities

Earliest Triassic Conodonts of Gua Panjang, Merapoh, Pahang and their Bearing towards Permian-Triassic Mass Extinction in Malaysia

“…Southward, Merapoh Limestone is known to overlain older Middle to Late Permian brachiopod bearing tuffaceous shale regarded as Leptodus Shale. This shale had been described by Campi et al (2002) and Mohd (1993) as a band (or possible presence of a few bands) of fossil-rich shale layer(s) extending across Sungai Yu -Sungai Toh area. Northward of Gua Panjang towards south Kelantan, sediments deposited and fossils found of younger age were recorded.…”

“…Similarly, the Gua Sei limestone is also underlain by thick to massive brachiopod rich tuffaceous shale (Mohd 1995(Mohd , 1993. These volcanic activities might be one of the cause for the extinction of marine benthonic fauna, which happened gradually from as early as late Middle Permian to Late Permian in northwest Pahang (Campi et al 2002;Mohd 1995Mohd , 1994. The latest Permian and earliest Triassic limestone at Merapoh and Gua Sei seems to be rather barren and lacked of fossils especially the benthonic fauna.…”

Sedimentologi Batuan Enapan Daratan Kumpulan Gagau (usia Kapur Awal) di Hulu Sungai Chichir, Terengganu Darul Iman, Malaysia

“…Tafsiran Fasies ini selalunya terbentuk akibat kesinambungan arus deras berketumpatan tinggi (Kneller & Branney 1995 (Campi et al 2005(Campi et al , 2002Mohd Shafeea 1994, 1993 Kebanyakan singkapan di sepanjang Sungai Chichir menunjukkan regim pengenapan yang berbeza daripada pengenapan secara ampaian bertenaga rendah (F.G7) hingga kepada pengenapan arus bertenaga dan berketumpatan tinggi yang singkat tetapi berterusan (F.G6). Bagaimanapun, sukar untuk ditentukan sekitaran pengenapan kerana singkapan di sepanjang sungai ini seringkali tidak menampilkan assosiasi fasies yang jelas.…”

Mesothermal Lode Gold Deposit Central Belt Peninsular Malaysia

“…The Eurasian Terrane (Manabor block) has been interpreted as Permo-Triassic island arc system which never been far separated from ShanThai block. Stratigraphic, palaeontological and palaeomagnetic evidences suggest a possible origin of these terranes by the rifting of the north-east margin of the ancient Gondwanaland landmass in the Late Permian to Latey Triassic that responsible for the formation of the Central Belt and the Raub-Bentong Suture (Cocks et al, 2005;Metcalfe, 2002Metcalfe, , 2000Metcalfe, , 1988Campi et al, 2002;Spiller and Metcalfe, 1995;Schwartz et al, 1995;Mitchell, 1977;Yeap, 1993;Tan, 1996Tan, , 1984Tjia, 1989Tjia, ,1987Khoo and Tan, 1983;Kobayashi and Toriyama, 1970).
