"Zealandia: Earth's First Fully Mapped Continent"
Geologists have discovered the submerged continent of Zealandia, twice the size of India, beneath the southwest Pacific Ocean. A new geological map has been compiled using rock samples and geophysical mapping methods, revealing large sandstone formations and basaltic rock pebbles that suggest Zealandia was gradually flooded around 40 million years ago. The study, "Reconnaissance basement geology and tectonics of North Zealandia," was published in the journal Tectonics in 2023.
