| Summary: | The ancient sedimentary rock from the field outcrop gives information on sedimentary features and enhances the depositional environment history. This research incorporated the information on the past sea-level fluctuations of sedimentary rock succession of Perlis area, particularly in Guar Sanai, Kampung Guar Jentik, and Bukit Tungku Lembu, Beseri area, to verify the events imprinted in the rock record. The data survey was carried out on 10th November 2018 during the mid-semester break. Therefore, this study overview was carried out to analyse the sedimentary facies and reconstruction of the paleo-environment history model for this rock profile via sedimentology logging, facies analysis study, and Fischer plotting analysis. Sedimentological and sequence stratigraphic evidence indicates that the Bukit Tungku Lembu outcrop represents a deposit of coastal, wave, and storm-influenced shoreface shelf system that reflects a shallow marine near fluvial paleo-depositional environment, and the Chuping Formation represents a restricted shallow marine environment. In contrast, the Guar Sanai outcrop represents a deeper marine to shoreface environment with glacial marine deposits. Six sedimentary facies have been recognised in Guar Sanai are which are; (F1) limestone interbedded with black mudstone, (F2) black shale, (F3) black mudstone interbedded with chert, (F4) mudstone, (F5) sandstone, and (F6) diamictite while five sedimentary facies in Bukit Tungku Lembu area which are; (F1) coal, (F2) silty shale, (F3) shale, (F4) sandstone, and (F5) interbedded of sandstone with silty shale and, three sedimentary facies of Chuping Formation which are; (F1) brecciated limestone, (F2) dolomite, and (F3) limestone. |
