Hope no one minds, but I felt we have to have a new topic, right from the start, as a compendium of all the Factual Observations on this incredible structure...this Mother Ship from another world...this...(who said Burgess Shale? I laughed at that at the time. ) Who will start us off with a detailed description of what we see before us TODAY February 5, 2006 - Super Sunday.

The bomb sag hypothesis is that the rock is actually a volcanic bomb that landed in some squishy sediments, producing soft-sediment deformation.

And then got conveniently tilted 90 degrees... ...I have my doubts about some of this. It seems a bit much to invoke gradualism *and* catastrophism on one site (I remain an acolyte of Arthur Holmes!).

To me the layers look fairly horizontal and the bomb sag hypothesis is quite probable. The only other process I know of that can produce similar structures is glacial dropstones from icebergs that fall into soft bottom sediments. In both cases deformed rather than disrupted layers is quite common. tty |

Not that I'm seriously suggesting it as an explanation here, it's just that (now that I think about it) I've never seen such a thing, and presumably a lump of stone tunneling towards freedom ought to leave some sort of trail...

Bob Shaw er yeah, one would similarly wonder if impact ejecta could give a similar appearance if it fell onto a muddy plain... no volcanic origin necessary... just a terrestrial rock, perhaps by chance even originally volcanic, but sunk into the soft layered sediments completely via non-volcanic (or even as thrown about in this thread, freeze/thaw or glacier) processes. how could we tell the difference? |
