I have a suggestion for you. Look up, on KZitem, a group called #The Finders , they are a rockhound group of KZitem content providers mostly specializing in agate, jasper and petrified wood. I think that you would enjoy seeing how folks go about discovering the specimens that you seem to really enjoy. Keep learning and some day you will be holding a degree in the STEM field.

How do they determine what type of tree it was?

Hi Shawn, different types of trees have specific pattern of the organization of the vessels in the wood. When cellular structure is preserved in the wood ("petrified" wood), trained specialists can recognize to what type of tree it belongs to. The easiest is to tell apart between softwood and hard wood but you can often determine down to the exact species, especially if you have cuts in both vertical and horizontal directions.

Can you clarify something for me. When petrification happens, a lot of geologists say the organic material is replaced, but from what I can see it isn't removed, it has been fused with the silica that has crystallized in the in the cell pockets. Is this correct?

Hi, I'm not a gemologist but here is what I think. Minerals enter the wood in the form of solution, which infuses the organic material and starts crystallizing, probably, similar to how stalactites in caves are formed - layer by layer, depending on what reaches the trunk (rains, volcanic fallout or new sediments can form on the top either at once or in periods. The diffusion in and out can still happen. An example - stained agates. The agates are kind of porous and may contain about 1% water. The organic material should degrade because the organic molecules are less stable than crystals and prone to enter various chemical reactions with ions around them. Many of them are polymeric and tend to break apart outside conditions created withing living cells, thus, leading to diffusion out of the semi-petrified wood. The space they occupied is replaced with silica and other minerals. Since, the process is step-wise, it creates irregularities in the structure - same way as layers on agates. Those irregularities reflect the wood structure and we can often recognize the individual cells or vessels based on how they look (the way the rock (final product) interacts with light - color, density, reflection are different). Some original minerals that were part of the organic material (Carbon, Fe, Mn) may be incorporated to the final structure/crystals but most of the minerals are likely from outside (sediment around the trunk). Otherwise, the wood would be much darker, like coal, which consists mostly of carbon. Imagine somebody walking on a beach and leaving footprints. We can recognize a part of human body in them but the sand and the foots that left the imprints are totally different things. I hope it helps.

@@KOIstories The two step process is what was missing from other geologist's explanations. It makes sense that after the mineral solution crystallizes in the cell cavities, the original organic material would decay away and then a new solution would fill its place creating the different coloured patterns. At least I know now that the entire organic matter is completely replaced, with the elements from the organic matter having a small chance of bonding with the mineral solution to create different mineral combinations.

Cool... I also suspect (and it's only a guess) that some baking or pressure-cooking happening underground like pottery firing, especially in areas with volcanic activity but it may be not always the case. If you want to learn from real scientists, look for an open-access publication by by George Mustoe and Marisa Acosta "Origin of Petrified Wood Color".

It depends on the size, origin, type of wood, preservation, polishing etc. Search for "petrified wood" on Ebay.com and you will have pretty good idea about the price for pieces similar to yours. Good luck!
