STRATIGRAPHY OF PALEOGENE SEQUENCES IN WESTON – SIPITANG, SABAH

This study is aimed to renew the stratigraphy in Weston – Sipitang especially for Temburong Formation and Crocker Formation which are known as the Paleogene sequences. The interfingering relationship between Temburong Formation and Crocker Formation shows that the Temburong Formation is older than the Crocker Formation in terms of stratigraphic sequences which had been the opposite. Facies analysis, facies association studies and the correlation of lithostratigraphic units in the study area and earlier studies helped to interpret stratigraphy and renew the position of stratigraphic for the Paleogene sequences. Temburong Formation and Crocker Formation are dated as Upper Eocene to Lower Miocene age.
