K-Ar dating of fault gouge in the northern Sydney Basin, NSW, Australia - implications for the breakup of Gondwana

Zwingmann, H; Offler, R; Wilson, T; Cox, Stephen

Description

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...[Show more]
