I'm going to ask a big favor here: Please READ OUR POSTS. There have been several explinations for potential methods for forming these features which don't involve anything as advanced as bronze. My method requires sand and a flat rock, for example. Continuing to argue against the use of bronze tools shows that you are not paying attention; you are, in effect, playing solitare.KotA said:First, I'd like to say that IF the stones that feature descending squares, that were designed to interlock with others are made of sandstone, 'soft-andesite', or some other easy to carve stone...I would concede that bronze tools might well be up to the job.
Also, you again show a complete lack of knowledge of rock. There's sandstone and then there's sandstone. It's a suite of lithofacies. I've seen some that crumble as soon as you pick them up, and I've seen some that felt like a solid lump of quartz (rounded quartz clasts with quartz cement--nasty stuff to have to make thin sections out of).
And finally, with a coarse-grained rock like diorite (relatively speaking, of course) it's entirely possible to carve the stone with a material much softer than the stone. You want to CUT the stone; I'd be satisfied with merely BREAKING the stone. I've broken a lot of very hard materials with my rock hammer. Rough it out with a hammer, then smooth it up with grit (which, by that time, you will be well supplied with) and use a flat slab you cut off from another rock to polish it. Done. We're talking tools entirely made out of stone, wood, and rope. Give me bronze and I can come up with MUCH more efficient methods.
Argument from Personal Incredulity is still a fallacy, even when you use someone else's incredulity.King of the Americas said:So, can you tell me how the line was made or not?
If you can't then the technology to make it has been LOST.
To be honest, I probably am as well. I know that the Paleocene glaciation was on Gondwana, but I thought there was an earlier glacial episode. Now that I think about it, though, I'm not sure. To be honest, we never discussed Snowball Earth episodes much.Correa Neto said:Not sure regarding the early Paleozoic snowball. Its not my turf, since I work with late Archean to early Proterozoic stuff, but I have the impression the extension of continental Paleozoic glacial deposits have more to do with the south pole being located within Gondwana than with a sonwball Earth episode. The contents of the following links seem to agree with my impression, but again, not my turf and I may be dead wrong.
Amen to that. I studied geology in Ohio. I know exactly where the glaciers stopped--I've stood on the mound they left when they stopped. The geology building at Kent State University is on a glacial morain, one of the smaller terminal morains left over when the glaciers retreated (they don't retreate smoothly). Literally everything south of the terminal morain--which is in Ohio--by definition was not impacted by the glaciers. Central America is a bit of a drive from Ohio.Correa Neto said:The important thing is that only the Quaternary glaciation (2.6Ma to now) matches the timespan of Homo genus and it was/is not a snowball Earth event,
Yup. Look them up in Google Schollar and you'll get all the data you need. Or, look at the references in the Wiki article YOU CITED. Sorry, but I don't encourage lazyness when it's tied to arrogance.KotA said:Is there a book or publication that fully documents the site, and tests each stone for a specific hardness?
