Green obsidian from columbia8/1/2023 Nope, there is absolutely no manufacturing, etc. TOO FREAKING COOL.Ĭould be a foreign implant. to the gov't of bc sites and to a book - "Geology of the Norhtwest Mainland" by Allen Gottesfeld, published by the Kitimat Centennial Museum Association (1985) ISBN 0-969 Another authority on the area, is Eileen Van der Flier-Keller (in an unrelated tangent - check out her little laminated guide, "A field guide to the identification of Pebbles" ISBN-10: 1-55017-395-2 - it is the COOLEST rock ID guide I have ever found and it's LAMINATED, fold-out brochure. I'd refer folks interested in the geology of the cordilleran range, our accreted terraines, etc. Not a chance in hades that that is green lava glass or that it originated in or near the Nass valley or the T'seax flows. So, here's the short version.įrom what I know, and according to what my friends who are geologists, miners, assayers, etc. and then closed the wrong freaking tab and lost it all. I just spent 1/2 an hour typing a response, citing sources, etc. It's certainly not industrial slag as there's no industry in that vast area, and I know it's not diamond - it's too soft for that and also I doubt that there are diamonds anywhere in the world that are that color and that are the size of boulders as big as a man. Yes I've done scratch tests, and it does scratch glass, and I've examined it under my microscopes. I know that perlite is used in the slag glass industry for just that purpose. ![]() But perhaps that's a good idea so I can find out whether or not the pearly inclusion is liquified perlitic mineral (perlite) which apparently is a common occurrence with vulcanism and does create a pearly appearance. ![]() I've never taken the obsidian to any 'authority' as there's never been a need to do so. If you think you might be interested there's more information here on this link en./wiki/Northe.lcanic_Province and included in that link is information about the location where my obsidian came from, the Tseax River Cone. ![]() If they (or you) want some rock-hounding excitement in your lives then I recommend an extended field trip to the area some fine summer. I don't know who you sent my pictures to but whoever they are I'm guessing it's someone who isn't familiar with the Northern Cordilleran Volcanic Province and the minerals there. I teach about stones and minerals on a different forum.
