Exact excerpt

The result: in the Dewar region, beneath the lunar surface, lies a rock body approximately 60 kilometres wide, extending to a depth of around 9 kilometres. It is much denser than the surrounding crust, while strongly magnetised at the same time. Combined with the surface geochemistry and an arched topography, the researchers conclude that this is solidified magma that has risen from the subsurface – a buried volcanic complex. The age of the structure – 4.2 billion years – can be determined from the various deposits of impact material on the lunar surface.
