Scientists Discover Lost Continent That's Been Missing for 375 Years
Scientists have recently discovered the existence of a continent that was hiding beneath the waves. While the land mass is underwater, it is undoubtedly there, and some of it is known as the islands of New Zealand and New Caledonia. The continent called Zealandia was confirmed to exist after decades of research by geologists. It is also known by its Māori name, Te Riu-a-Māui.
Zealandia Is the Eighth Continent
The eighth continent seems to be over a billion years old, and its existence was first proposed in 1995. It was fully mapped in 2023, and a 2021 study suggested its age. Back in 2018, geologist Rose Turnbull stumbled upon grains of sand containing a mineral called zircon. The mineral is important because it can be used to trace all kinds of igneous rocks, like granite, that form on continents.
During the study, 169 samples of rock were crushed and sorted until only fine sand and zircon crystals remained. With those zircon crystals, the group could advance and publish their study, showing bits of mantle rock from Zealandia that were as old as 2.7 billion years. According to researchers, the discovery ticked the final box to pronounce that the land mass was actually a continent.
