The concentrations of 19 elements were determined in organic and inorganic phases of the Julia Creek Oil Shale (Queensland/Australia). The phases were obtained by solvent and alkaline extractions as well as by stepwise demineralization with strong acids. Together with the results of other groups, a consistent model concerning the partition of trace elements in the various sedimentary components could be achieved. Whereas V, Ni and Ag show distributions comparable to the abundances of the correspondent phases in the sample, Ca, Mn and Co are concentrated in the mineral components, and B, As and Pb are enriched in kerogen. Al, Cr, Fe, Cu, Zn, Mo, Cd and Sb range between these extremes, while Au and Hg are contained in the humic substances only.
