Sedimentology and potential coal resources in susui block, Pinangah, Sabah

The Susui Block in Pinangah area located northwest of the greater Maliau Basin in central Sabah is underlain by the coal-bearing Tanjong Formation of Early-Middle Miocene age. This study was conducted to determine the sedimentary characteristic of the coal bearing sequence, the quality of the coal a...
