Abstract: The Kinta Valley of Perak, Malaysia is a geologically significant region characterized by Paleozoic carbonate deposits, karst landscapes, and a rich fossil record. This study focuses on the sedimentological description and depositional interpretation of carbonate pinnacles once exposed at Putra Terminal, Kampar, which have since been demolished due to urban development. A total of 26 pinnacles were surveyed, with seven logged in detail to construct two continuous lithostratigraphic sections. Five facies were identified: stylolitic limestone (M), laminated limestone (LL), oval detritus limestone (F), bioclastic limestone (BL), and brecciated limestone (Bc). The facies association indicates a dominantly shallow-marine depositional setting ranging from peritidal to a classic reef environments, with episodic higher-energy influences. Fossil assemblages, including gastropods, horn corals, and possible fusulinids, provide evidence for a Late Carboniferous to Permian age. Diagenetic overprinting, particularly dolomitization, was pervasive and restricts microfacies analysis. These results contribute to the broader understanding of the Kinta Limestone Formation and underscoring the importance of documenting rapidly disappearing geological sites within Malaysia’s karst landscapes.
