This paper deals briefly with the geology and mineralisation of the Ediacara Mineral Field, which is located about 300 miles north of Adelaide in the Mount James Range._x000D_
The field was discovered sane time prior to 1872. Total recorded production for the field amounts to a few hundred tons of lead and 36 tons of copper. Re-listing of the field during 1961-62 led to its classification as a Mississippi Valley type deposit. Diamond drilling has partly outlined the spread of mineralisation and confirmed its stratiform distribution, Sources for the metals are suggested and various possible mechanisms._x000D_
of deposition are described.
