A thick sequence of conglomerate, tuffaceous sandstone and shale/mudstone largely exposed at the Setia Jasa area is described. The matrix-supported conglomerate of very well rounded clasts conformably overlies pebbly mudstone and shows a gradual change in matrix grain size from clay to sand. An Anisian (early Middle Triassic) age is indicated for a whole sequence by the presence of an ammonoid Paraceratites sp. found in a lower shale bed. Sedimentological features suggest that the conglomerate and underlying sandstone/shale sequences were possibly deposited in a relatively deep marine environment, and probably belong to the Semantan Formation.
