Scientists discover giant blobs deep inside Earth are 'evolving by themselves' — and we may finally know where they come from
Others have suggested that the blobs are huge chunks of oceanic crust that were pushed into the mantle when one tectonic plate slipped under another — a process known as subduction. The crust ...

Scientists reveal evolutionary history of continent-sized regions in the deep mantle
One common hypothesis is that the LLVPs are made up of oceanic crust that was pushed into the mantle at subduction zones. This crustal material was then stirred through the mantle over millions of ...
