By "relevant forces" I was simply referring to the whole gamut ranging from EDM scarring, electrical deposition, plasma discharge "burn scars" (which I guess are a type of EDM), and IMHO electromagnetic forces which (A) I assume are strongly in play during a gigantic discharge event, and (B) are likely responsible for any (or at least "most") of the geologic features which display some sort of rotation. I like the term "geologic vortex" but I don't know if that's strictly accurate.starbiter wrote:Hello Shelgeyr,
I searched "relevant forces" and can't figure out Your usage of the word.
I wasn't trying to be overly-mystical or unclear... It is just that while we're attempting to explain crater formation I wouldn't want us to lose sight that there seems to be some pretty strong evidence that far larger structures, on a planetary scale (including - again IMHO - the planet itself) were formed by the same EM discharge forces that on a smaller scale formed craters.
To take this further, I'd like to suggest that just as a "rim crater" could be formed by an EDM "after thought" on the edge of a larger crater, and that the formation of either would have been spectacular to see (should there have been any survivors to the event), even the largest craters on our planet could probably be seen as a minor "oh, yeah, and that discharge also made that crater" type of thing compared to whatever major discharge was going on.
I'm rereading what I just wrote, and I think I've done a fairly poor job of explaining what I mean, so bear with me and I'll try to follow up in the near future with either a better explanation, or graphics, or both.
Hi Shelgeyr,
The geologic column can help us understand the process of catastrophic geology to an extent. I try to list as many options as my imagination can produce, even though i may have a preference. If basalt covers a surface it seems reasonable to assume the basalt came after whatever it covers.
Many "craters" that i see in the field have no explanation other than an attractive thunderbolt pulling in iron rich dust. A volcano is NOT an option in many cases, even with an overactive imagination.
Meteor Crater is interesting in that it has a raised rim. The rim seems to have folded up. The rim of meteor crater is the only example of folding i've seen in almost 5 years of field research. An impact might be the cause of the surrounding strata being pulled up, but i'd put my money on a thunderbolt removing the missing material. It appears to my eyes that some thunderbolts attract, and some thunderbolts repel material. Attraction seems much more common.

I agree that there were vortices within the massive vortex events. A chaotic bummer.
