What is that diamond/cone formation in the Satisfactory promo?

One of the promo images found on the Steam Page shows an almost diamond/cone shape formation in the middle of a mess of conveyer belts with a structure ontop of it

i haven't explored the entire world yet but of what i have seen i have never came across anything like it yet.

So i am wondering what it is? if it's a natural land formation or something man made (out of what if we know) and where in the world is it depicted as being located at?

By the looks of the conveyor elevators seemingly attaching to it, it's just a ton of conveyor belts arranged in an upward spiral fashion, similar to as seen in this video.

Apart from looks, I wouldn't say this is a particularly inefficient design, and it seems like your computer will take quite the resource hit from building such a structure.

Lets Game It Out made it in his video.
It is not a thing in the game and wont spawn.
(everything he does is a spectacle, so if you see his name disregard it)
