Field observations indicate that shale intervals of Triassic turbidites from the Semanggol and Semantan formations in the Peninsular Malaysia occur as thick-bedded dark grey to black shales overlying conglomerate, pebbly sandstone, thick-bedded sandstone, and sandstoneshale interbeds. This sequence characterises a submarine fan depositional setting where the conglomerate, sand and sand/shale intercalations represent an inner and middle fan setting in a shallow marine environment, whereas the black shales were deposited in a deeper marine environment of the outer fan. The redox-sensitive trace-metal inventory (V, Ni, Cr) of the black shales is dominated by clastic input and the depositional environment is likely oxic/suboxic. TOC values are highly variable (3.2 ± 3.3 wt.%) and derive from washed-in allochthonous organic material.
