Chronostratigraphic Chart of The Sedimentary Basins of Malaysia

A stratigraphic chart incorporating all major Cenozoic Basins in Malaysia was constructed by Petronas. This chart reflects the most recent interpretations of Malaysian stratigraphy and correlations of east and west Malaysia. Our goals are to generate a comprehensive chronostratigraphic chart and increase the success rate of hydrocarbon exploration and production in Malaysia. The chart compares stratigraphy of eight major basins in Malaysia: Sabah, Sarawak, Malay, Penyu, Natuna, Straits of Melaka, Tarakan, and Sandakan Basin. It includes major lithostratigraphic units as well as biozonations and key biostratigraphic markers. In addition, three different geologic time scales were integrated with two eustatic sea level curves. The chart collates interpretations from hundreds of geoscientists who published within the last 50 years. Nomenclatures are referenced to the original author(s) as well as subsequent author(s) when possible, and in most cases have been reviewed by the source. This chart should<br>be considered a work-in-progress that will require future inputs.
