... system whose duration spanned a transition from weakly hydrostatic to overpressured conditions. Metal deposition at Cadjebut lasted from the Late Devonian to mid-Carboniferous time, a period of up to 35 m.y. The higher hydrocarbon content of the later breccia ore suggests that oil and gas generation...

... in the Lennard Shelf, Canning Basin, northwestern Australia. Sulfides at Cadjebut and the other Lennard Shelf MVT deposits precipitated from overpressured, hydrocarbon-rich brines. The deposits lie below a major mid-Carboniferous unconformity that is linked to a global sea-level fall. Independent evidence...

... of the barite also suggests that evaporites in the Cadjebut Formation ( Hocking et al., 1996 ), which have δ 34 S values of about 20 per mil CDT ( Tompkins et al., 1994b ), did not constitute a source of sulfate for the deposits. Sulfur isotopes enriched in δ 34 S have been recorded where bacterial...
