Lithosphere in australia
WebWithin Phanerozoic eastern Australia, a robust negative Sp phase is found at depths of ~60-95 km. The negative phase is shallowest and strongest beneath stations COEN (67±8 km) and TOO (61±11 km). These stations are located at the northern and southern ends of the Phanerozoic terrane, near the most recent volcanic activity. Web3 nov. 2015 · Most notable is the distinction between oceanic and continental lithosphere. Also evident are the internal divisions within continental Australia, including major sedimentary basins and crustal uplifts of central Australia and the complex structure of the convergent margin to the North.
