Ancient Oceanic Crust Found in Mediterranean Sea 70 Percent Older Than Any Known Seafloor

Dr. Return of investment Granot, a senior speaker in the Department of Geology and Environmental Sciences at Ben-Gurion University of the Negev (BGU), has actually determined an ancient oceanic crust listed below the eastern Mediterranean Sea that has to do with 70 percent older than any known seafloor. The seafloor slab, explained in a paper released in the journal Nature Geoscience, has to do with 340 million years of ages, around 150 million years older than the previous record holder located east of Japan. Dr. Granot believes that the 60,000 square mile piece of crust was a remnant of the Ancient Tethys Ocean, which existed long before the Atlantic and Indian Ocean.” [W] e do not have undamaged oceanic crust that old … It would suggest that this ocean was formed while Pangaea, the last supercontinent, was still in the making,” Dr. Granot informed Business Expert. Pangaea is known to be a supercontinent before newly forming ocean divided it apart less than 300 million years earlier. Nevertheless, the discover of the 340 million years old oceanic crust suggests that the supercontinent began disintegrating prior to it was completely formed or that the section where the crust was found is already existing even before Pangaea occurred. Due to the very thick sediments covering the crust in the eastern Mediterranean and little size of the basin, the seafloor slab stayed to be unnoticed until now. To figure out if an oceanic crust is hiding below the Mediterranean Sea, Dr. Garot and his group gathered marine magnetic profiles throughout Herodotus and Levant Basins using magnetic picking up devices. After examining the nature of the magnetic information in the crust of Herodotus Basin, Dr. Garot discovered that the rocks are defined by magnetic stripes. Magnetic stripes is the striped pattern in mineral orientations formed when molten lava cools off, making the magnetic minerals within it to align themselves Earth’s geomagnetic field. The flipping of the Earth’s north and south magnetic poles forms the magnetic stripes for over millions of years. Dr. Garot kept in mind the future research studies are still had to validate his discovery.
