Abstract
- Due to limited information, this paper aims to present a detailed facies analysis and depositional environment of the Carboniferous age, Singa Formation at Pulau Ular, Langkawi, Kedah. One exposed outcrop at Hill C was examined in detail, and one sedimentary log was created. The log is categorized bed by bed into several facies according to lithology and sedimentary structures. The focus was to identify the facies succession and to analyze the depositional environment as Singa Formation. This study is vital to reconstructing the pattern of past glacial as it will provide the crucial link between glacial processes and history, ice masses, and a more comprehensive Earth system. The Singa Formation is concluded into coarsening upward facies successions based on the facies succession grades upward from offshore facies. The depositional environment of Pulau Ular is interpreted as a coastal and a glacier depositional environment. Eight facies have been recognized; shale (FC1), shale with burrows (FC2), siltstone (FC3), shale with burrows, clay to silt (FC4), laminated shale with dropstone (FC5), sandstone that consists of dropstone (FC6), shale consists of dropstone (FC7) and sandstone with diamictite rock (FC8). Facies shale, sandstone, and siltstone proved that the study area is a coastal depositional environment, while facies consisting of dropstones and diamictite show that the study area is a glacier depositional environment. • To give a detailed facies analysis and depositional setting of the Singa Formation. • The Singa Formation is best seen in the exposed rock of Langkawi and north Perlis. • The Singa Formation consists of four members: Rebak, Kentut, Ular and Selang. • The facies of Pulau Ular indicate a coastal environment and glacial marine deposits.
