in the northern Sydney Basin, NSW, Australia-implications for
the breakup of Gondwana Cox, S. F. - The University of
Newcastle. Faculty of Science & Information Technology, School
of Environmental and Life Science - The occurrence of
synkinematic and authigenic clay minerals is a common feature in
fault gouges. Few attempts have been made to date fault gouges.
We present the first age data in Australia for synkinematic
illite–smectite growth in two fault zones of the northern Sydney
Basin, NSW. The faults occur at Burwood Beach, NSW in the
northern part of the Sydney Basin and are hosted by Early
Permian siltstones, tuffs and coals of the Lambton Formation,
Newcastle Coal Measures. The faults are 1.5 m apart, show normal
displacement and trend N–S with steep easterly dips. Foliated
gouge zones, comminution and dilational breccias are developed
along both fault surfaces. K–Ar ages extracted
