Yup! Uplift and seduction!
A”Eastern Australia was drifting over a subducted plate graveyard, giving it a sinking feeling,” said co-author Dr Kara Matthews, a former PhD candidate at the University now at the University of Oxford. “But around 100 million years ago subduction came to a halt, resulting in the entire region being uplifted, forming the Eastern Highlands.”
Its all about uplift and subduction.
Ain't that the truth.
Sigh.
The lingering effects of subducted plate is relatively new. At one time, the mantle was thought of as a fairly uniform layer of plastic rock under heat and pressure moving as convection currents and now there are some surprises. Everything that was theorized before still has elements of fact but new ideas raise even more questions as they should.
Yup! Uplift and seduction!
