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.
