General Geology of northern Gunung Semanggol, Bukit Merah, Taiping with emphasis on Tectono-Stratigraphic Evolution of Semanggol Formation

Previous researches of northwest Peninsular Malaysia have classified Gunung Semanggol as part of the Semanggol Formation that extends from north and south Kedah. The study presented in this paper aims to investigate the geological outcrops along the west and east face of the northern Gunung Semanggol. Data recorded during the research is used to conceptualise a sedimentary facies model, depositional
settings and tectono-stratigraphic model. The methods used are geological fieldwork and laboratory works including thin section and petrography analysis. The results show that the outcrops exhibit fining upward sequence of bedded chert, and
sandstone interbedded with shale, as well as some siltstone. It is postulated that the northern Gunung Semanggol was once deposited in deep marine settings that lead to deposition of bedded chert, followed by deposition of turbidite materials. The age of the northern Gunung Semanggol formation is suggested to be Permo-Triassic. The data presented in this paper are valuable in understanding the geological link
between outcrops of the Semanggol Formation. It is recommended that other aspects such as biostratigraphy and geochemistry to be included in the future to gain accurate
distinction between Permian and Triassic rocks formation of the northern Gunung Semanggol and the Semanggol Formation exclusively.
