DiggerGuyy Posted May 7, 2019 Share Posted May 7, 2019 I have found a burned petrified and opalized tree buried under a hundred feet of basalt with plenty of mineralization. I am trying to find out where i can have it identified and appraised. Thank you for your help. This was found in the northwest United States in the Colombia river gorge in Oregon.

Fossildude19 Posted May 7, 2019 Share Posted May 7, 2019 The Forum does not do appraisals. As far as ID, it is my understanding that thin sections need to be taken to make any significant ID. These are just usually labeled petrified wood. These aren't uncommon finds, so I wouldn't expect much in the way of a payoff from this. "Gem quality" petrified wood is not that expensive. 1 Tim - VETERAN SHALE SPLITTER VFOTM --- APRIL - 2015 __________________________________________________ "In every walk with nature one receives far more than he seeks."

Auspex Posted May 7, 2019 Share Posted May 7, 2019 I'm curious as to how you can tell it was burned? 1 "There has been an alarming increase in the number of things I know nothing about." - Ashleigh Ellwood Brilliant “Try to learn something about everything and everything about something.” - Thomas Henry Huxley >Paleontology is an evolving science. >May your wonders never cease!

Therefore it must already be burnt. @DiggerGuyy Fossil/petrified wood is common. Any event large enough to fossilize entire tree trunks and forests is a major event, and therefore there is no rarity of kind or color that would greatly enhance its value with maybe one or two exceptions worldwide. This isn't one of them. 99.9% of the time if you can find one piece, there are probably at least a million more like it, usually withing spitting distance. Mark.

DiggerGuyy Posted May 21, 2019 Author Share Posted May 21, 2019 I do not know for sure if it was burned, it just looks like petrified charcoal. It may have been burned by ash from a volcano many years ago... Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted May 21, 2019 Share Posted May 21, 2019 Another possibility is that it was caused by a process similar to destructive distillation. Google it. Charcoal is not burnt, otherwise it would just lie there on the grill and refuse to ignite. Some of the branches and stems in a fire should have burnt all the way through. Is the evidence of heat/fire found only on the surface? It requires looking at many more specimens to form that hypothesis. So, to better understand the cause, you'll need to do a lot more investigation. Go for it! Mark. Fossil hunting is easy -- they don't run away when you shoot at them!
