The peculiarities of the formation of the structure of the Earth’s crust in the Australian–Antarctic basin during the early break-up between Australia and Antarctica are considered. The study period encompasses long-lasting rifting (~160–80 Ma), ultraslow spreading (~80–45 Ma) with the formation of...
