Abstract: Besides tin, the Kinta Valley is known for its lithology and biostratigraphy. Study on some Permian microfossils from the Kampar area indicates the presence of Maklaya (fusuline) at H.S. Lee Mine. This finding is interesting because Genus Maklaya and other taxa found at this locality are yet unknown in other localities in the northwestern part of Peninsular Malaysia and Peninsular Thailand. Maklaya indicates the highest horizon of Bolorian or to some authors, to the base of Kubergandian. Moreover, the Bolorian limestone at the H.S. Lee Mine possibly extents into the Yahtahsian and it may corresponds to a period without limestone deposition in the northwest Peninsular Malaysia and Peninsular Thailand. Furthermore, the characteristics shown by the lithology and stratigraphy of the Kinta Valley indicate that the palaeogeography of this area is different from the northwestern part of Peninsular Malaysia.

 

Abstrak: Disamping kaya dengan bijih timah, Lembah Kinta adalah juga menarik dari segi segi litologi dan biostratigrafi. Kajian yang telah dijalankan terhadap sebahagian fosil mikro berusia Perm di kawasan Kampar menunjukkan kewujudan Maklaya (fusuline) di H.S. Lee Mine. Penemuan ini adalah sangat menarik kerana Genus Maklaya dan lain-lain taksa yang ditemui di lombong ini, sehingga kini belum lagi ditemui mana-mana lokaliti di bahagian barat-Iaut Semenanjung Malaysia dan juga Semenanjug Thailand. Selanjutnya, batu kapur di H.S. Lee Mine berusia Bolorian berkemungkinan tersebar dengan meluas hingga keusia Yahtashian dan ianya mungkin berkait rapat dengan kala pemendapan tanpa batu kapur di barat-Iaut Semenanjung Malaysia dan Semenanjung Thailand. Maklaya menunjukkan ufuk bahagian teratas usia Bolorian atau bagi sesetengah penulis ia menunjukkan bahagian paling bawah usia Kubergandian. Disamping itu, ciri-ciri litologi dan biostratigrafi yang terdapat di Lembah Kinta menunjukkan kelainan dari segi paleografi dengan kawasan barat-Iaut Semenanjung Malaysia.
