| Abstract | Hadrynian through Mississippian strata of the Gataga area are involved in a northwest-trending fold and thrust belt. Stratiform barite and barite-sulphide mineralization in the black siliciclastics of
the Lower part of the Earn Group has been mapped over a stratigraphic inter val of 400 m and over a continuous to semicontinuous strike length of 50 km. Five mineralized horizons have been identified, three of which contain significant barite and
barite-sulphide accumulations. Intense/y deformed sulphide mineralization is found at the Bear and Driftpile deposits. The structure is dominated by large northeastwardverging thrust panels along the western margins of the Gataga area and steeply
east-dipping, west-verging thrust faults along the eastern margin. The Lower Earn Group siliciclastics are intense/y folded and faulted, hence thickness determinations are difficult and correlation of the mineralized intervals is hampered.
Structural and stratigraphie analysis indicates that the stratiform barite and barite-sulphide mineralization was deposited in a Late Devonian half graben system that was inverted during Mesozoic contractional deformation. |
