Some Upper Mesozoic palynomorphs from the Tekai River area, Jerantut, Pahang

A palynological study was carried out on rock succession which is exposed along Sungai Tekai, Jerantut, Pahang. Some fairly well-preserved palynomorphs were identified in a rock succession which is part of the Mangkin Sandstone Formation of the Tembeling Group. Sandstone is the dominant lithology in this area together with siltstone, mudstone, shale and conglomerate of various thicknesses, and interpreted to be deposited in a fluvial enviroment. The observed palynomorphs are assigned to twenty one genera which include the commonly observed genera namely Stereisporites, Biretisporites, Cycadopites, Laevigatosporites and Lycopodiumsporites. The identified palynomorph assemblage from this area is comparable with the Speciosus Assemblage of late Lower Cretaceous age. Abstrak: Kajian palinologi telah dilakukan terhadap jujukan batuan yang tersingkap di sepanjang Sungai Tekai, Jerantut, Pahang. Beberapa palinomorf yang terawet baik telah dikenal pasti dari jujukan batuan yang merupakan sebahagian daripada Formasi Batu Pasir Mangkin dari Kumpulan Tembeling. Litologi utama di kawasan ini merupakan batu pasir bersarna-sarna dengan batu lodak, batu lumpur, syal dan konglomerat dalam pelbagai ketebalan, dan ditafsirkan terendap di sekitaran fluvial. Palinomorf yang ditemui dikelaskan kepada dua puluh satu genera merangkumi genera yang biasa ditemui iaitu Stereisporites, Biretisporites, Cycadopites, Laevigatosporites dan Lycopodiumsporites. Himpunan palinomorf yang dikenal pasti dari kawasan kajian menyerupai Himpunan Speciosus yang berusia akhir Kapur Awal..
