Title. 551.700595 Published by Geological Society of Malaysia Department of Geology, University of Malaya, 50603 Kuala Lumpur Tel: 603 - 7957 7036 Fax: 603 - 7956 3900 E-mail: [email protected] Printed by Art Printing Works Sdn. Bhd., 29 Jalan Riong, 59100 Kuala Lumpur FOREWORD This much-awaited Stratigraphic Lexicon of Malaysia is a welcome resource to geologists, especially stratigraphers working in Malaysia. Although, this is not the first attempt to compile the rock units of Malaysia, this Lexicon is the first comprehensive review and compilation of both formal and informal Malaysian stratigraphic units. It contains 160 systematic description of formations. It also contains extensive bibliographic and chronologic information as well as fossil records, which are useful starting points for researchers that require further data for their work. It is hoped that through this Lexicon, with its easily accessible comprehensive information, problems related to stratigraphic work in Malaysia can be addressed and improvement on the relationship and correlation between the stratigraphic units be achieved, leading to a better understanding of the geology of Malaysia. This Lexicon is the result of the hard work put in by the Malaysian Stratigraphic Central Registry Database Subcommittee (MSCRDS) that was set up in 1995. The MSCRDS comprises of dedicated stratigraphers from the Minerals and Geoscience Department Malaysia, the Geology Departments of University of Malaya and Universiti Kebangsaan Malaysia, and PETRONAS. I would like to extend my appreciation and thanks to the Geological Society of Malaysia and the key individuals involved for their fine effort. Dr. Chu Ling Hing Ketua Pengarah Jabatan Mineral dan Geosains Malaysia iii PREFACE Although a lot of work has been done in describing and mapping of stratigraphic units in Malaysia especially by pioneer geologists from the Geological Survey since its inception, almost all the stratigraphic names used are informal and published as mapping progressed in the various reports of the Geological Survey. These were supplemented by more informal stratigraphic formations erected by other geologists, notably those from the universities and others from the mining and petroleum industries over the years. Attempts to bring together these formations in a single compilation has resulted in the publication of Gobbett and Hutchison’s (1973) “Geology of Peninsular Malaysia” and Leichti, Roe and Haile’s (1960) “The Geology of Sarawak, Brunei and the Western Part of North Borneo”. While the Malaysian Stratigraphic Nomenclature Committee of the Geological Society of Malaysia was producing the Malaysian Stratigraphic Guide (Ahmad bin Jantan et al.,1997), the committee realised that there was a need to gather together all published stratigraphic data in the form of a lexicon so that later attempts to formalise informal units or erect new units would be made easier. A separate committee known as the Malaysian Stratigraphic Central Registry Database Subcommittee (MSCRDS) was set up at the beginning of 1995 to undertake the task. The subcommittee consisted of representatives from the Department of Geology in University of Malaya, Faculty of Science & Technology Geology Programme of Universiti Kebangsaan Malaysia, Minerals and Geoscience Department of Malaysia and Petronas. Published data up to 1997 on stratigraphic units in the Palaeozic, Mesozoic, Cenozoic Onshore and Cenozoic Offshore of Malaysia was gathered by members of the subcommittee following an agreed format of 14 categories of information for each stratigraphic unit. The categories are:- Name, Origin of name, Age, References, Type area, Type section, Boundaries, Correlation, Thickness, Lithology, Subdivisions, Fossils, Environment of deposition and Remarks. Data of varying detail from abundant to scanty has been compiled on 44 Palaeozoic, 37 Mesozoic and 78 Cenozoic Onshore formations. Stratigraphic formations that staddle era boundaries would be included with the section where the bulk of the sediments within the unit are found, for example, the Permo-Triassic Semanggol formation is placed under Mesozoic. The formations in each section are divided into those from Peninsular Malaysia, Sarawak and Sabah and arranged according to their ages from the oldest to the youngest in each section. The numerous Cenozoic Offshore formations had very different based for nomenclature depending on the various schemes used by the different petroleum companies and it was decided not to include them in the present publication. Since most of the Malaysian stratigraphic units have not been erected formally following the recommendations of the International or Malaysian Stratigraphic Guide, we envisage that much work would be needed to formalise the units and the information contained in this lexicon will provide the necessary background information for the stratigrapher doing it to build on. This lexicon contains published stratigraphic information up to 1997. More work on Malaysian stratigraphy has been done and published since then. It is envisaged that periodic revisions with new information on the existing formations and new formations erected after that would need to be added either as supplements to the existing lexicon or as revised editions of it in the future as stratigaphic work in Malaysia progresses. Lastly, I would like to thank all the members of the Malaysian Stratigraphic Central Registry Database Subcommittee and their respective organisations for their hard work and support in producing this lexicon. The editorial help of Dr. Ng Tham Fatt is gratefully acknowledged.
