‘Lost continent’ of Zealandia transformed by formation of the Pacific’s Ring of Fire

The ‘lost continent’ of Zealandia, which is submerged beneath the Pacific Ocean, experienced a major upheaval about 35 to 50 million years ago.

According to findings published Feb. 6 in the journal Geology, scientists now believe that the topographic transformation may have been related to a reactivation of ancient fault lines linked to the formation of the western Pacific’s Ring of Fire.

Scientists have long believed that Zealandia’s crust began to thin when it split off from Gondwana, an ancient supercontinent that included Antarctica and Australia, about 85 million years ago.

The Geological Society of America confirms that fossils in the drillcores that were collected in 2017 show portions of Zealandia rose 1 to 2 kilometers while other parts subsided about the same time before the entire continent eventually sank deeper underwater.
