What do the requiem pillars around Deimos do?

[LordFatCat]

I noticed there's a bunch of pillars scattered around Deimos identical to the ones you find at the vault door in the caverns with the requiem symbols on top. You can shoot them with void damage to activate them, but I haven't figured out what the ones on the surface do and am curious if anyone has figured that out yet.

Not sure about all of them, but at least one of them makes enemies killed by it drop rare resources:
