Scientists found signs of an ancient hidden sea off Philippine coast - senona - 08-25-2016 The Philippine Sea today
Quote:Geologists have discovered remnants of a long-lost sea that once ran between today’s Pacific and Indo-Australian oceans, spanning more than 15 million square kilometres around 52 million years ago. Source Expecting that they would just have to map one tectonic plate in the area, they soon realised that it harboured a veritable 'slab graveyard', with signs of several plates that have been slowly been sinking into Earth’s mantle - the thick, dynamic layer that sits between Earth’s crust and its upper core. Quote:While the mantle is mainly made up of silicate rocky material, it behaves more like a viscous fluid than a solid, because its temperatures are so close to the melting point. Once that jigsaw puzzle was complete, they found at least 70 million square kilometres' worth of these sunken slabs - equivalent to about one-seventh of the total Earth surface area. Quote:Reconstructing the history of these plates allowed the team to see how 15 million square kilometres of this buried material would have served as the bottom of the ancient, now-defunct East Asian Sea some 52 million years ago - less than 10 million years after the demise of the non-avian dinosaurs. Quote: Amazing.....this is a very interesting scientific discovery most definitely. Goes to show humans cannot stop a planet from going thru it's natural changes when it gets ready to. All we are is just a 'blip' on a planet that is 4.5 billion years old. Blame plate tectonics for the disappearance of this ancient sea Quote:The area around the Philippine Sea is better known for being a political hotspot than a geological one. But it turns out that the tectonic plate named for it is just as volatile. It’s located at the intersection of the Eurasian, Pacific and Indo-Australian plates — three plates, that, millions of years ago, swallowed up an ancient sea. They will be like kids in a candy shop, studying the ancient tectonic plates. Would love to know what else they pick up from them. Quote:It took five years for Wu and his colleagues to gather enough evidence to support the existence of the sea, which they think shrank over time as more and more plates in the area were subducted and lost. The shape of the sea fits in with a literal gap in plate tectonics — an area in the vicinity of the theorized sea whose lithology geologists haven’t been able to figure out. “Twenty-eight slabs later, we felt like we could answer that question,” he laughs. Indeed....who knows how many other oceans there are to be found. Great work guys!!
