Are there ever rockhound threads on /out/? Found these in high desert colorado, curious if anyone knows what they are. They're part of a petrified wood collection I found in a washout (next pic) and I'm curious what the type is that gives this unique orange yellow hue.
And this is petrified wood, correct? Got a dozen smaller chunks just want to verify it's actually petrified wood.Also it was public space before anyone gets their panties in a bunch.
>>2722957>public spaceby which I mean it was in previously untouched land between two new housing developments, so not public or private land really just a garbage wash with a few little coulees.
>>2722956>I'm curious what the type is that gives this unique orange yellow hueBest way to identify it is to lick it. Kek. But seriously, yellow-orange in rocks is usually from trace iron inclusions
>>2722956Looks like a type of limestone. I think it is quite common for them to have parts that contain oxidized iron, at least that's what my local limestone has a lot of. Some of these cracked open can reveal fossils.
>>2722957it does look a little bit like PW. Is it a spot known for it? I found a nice chunk of 50 million yr old redwood tree
>>2722957I'm not sure if that is petrified wood. It doesn't really look much like anything in my collection. I'll post mine tomorrow if I don't forget.
>rockhoundingbecause "i collect rocks" didn't sound gay enough
>>2722956>>2725333this is part of my collection. it looks very different from yours.a couple of your rocks looks kinda like it could be but it's hard to tell.
I've been doing geotech in southeast PA for four years and can find alot of nice stuff on the job or quarried onto site. Got a long term site in the reading prong thats full of gneiss finds . Happily surprised to see a rock thread. Been tile sawing alot this year with my finds.

>>2726444Best Fools Gold Vein I ever found cracking quartz looking for vugs on a site. Everything else is usually just pinhead sized bits in aggregate. We hauled alot of material but I could not find any more quartz. But i did find some nearly purple garnet in the Wilmington complex gneiss as we hit deeper beneath the oxidized layers
>>2726446Looks great cut and polished.No solid angled crystals in it though unfortunately. I find alot of that in the mica schist around philly just to the north though
>>2726444Case I did at local club's last show. It isn't tuscon but I'm always surprised at our turnouts. The golf ball sized garnet I have should be in there.

>>2722957I'll post mine. Providence is known, locale is Arizona (private land collection, not NPS or BLM). Yes it is petrified. I haven't bothered to polish it but you can see rings and bark and even a knot. Haven't weighed it but I would say it is about 10-15 lbs or on the lower side of that range, 8.5x11" notebook for reference. 1/3
