Az_Ed Posted November 27, 2022 Share Posted November 27, 2022 I found this odd rock out in Gold Basin. I've sent some photos to some experts who think it is not a meteorite, just thick desert varnish. It sure had me wondering for a while since it seemed so out-of-place compared to other material nearby. 2 Link to comment Share on other sites More sharing options...
jasong Posted November 27, 2022 Share Posted November 27, 2022 There are actually extinct volcanoes and old flows around Gold Basin. As a result, there are sometimes scattered pyroclasts in places you wouldn't expect. That appears to be one such piece. They are fine grained and in the general rhyolite->andesite->basalt tuff series of rocks, probably more towards the basalt end of the series. They vary but tend to be hot on a detector, up to screaming in some cases. From a picture only, that's what I'd guess that rock is. You could always take a file or battery powered angle grinder and make a window into it though and look for metal flecks and chondrules if you have doubts in person. 8 Link to comment Share on other sites More sharing options...

JRJR Posted February 7, 2023 Share Posted February 7, 2023 Anywhere from some to lots of magnetite in these rocks. Link to comment Share on other sites More sharing options...
MSC Posted February 7, 2023 Share Posted February 7, 2023 I have found GB meteorites and this does not look like any I have found. I am sure you are correct jasong. Link to comment Share on other sites More sharing options...
