(Coal in Ombilin basin mined in Sawahlunto area since 1891. Basin fill ~4600 m of M Eocene- E Miocene
sediments. Fan-delta sediments below oldest M Eocene seam, seam itself and sediments overlying C seam
investigated along W margin. Ombilin Basin is a graben-like 'pull-apart' basin. Debris flows and fan-delta
formation around margin of basin, with lake sediments in basin centre. Peat accumulation influenced by
underlying fan-delta lobe geometry. In interlobe areas thick sequences of low ash peat accumulated, while
central lobe areas high ash coal or carbonaceous shale formed)
