That's worth logging in for. Some of that shrinkwood is as good as it gets! Outstanding specimens.
Thanks for the photos, but this thread should have come with a drool warning.

Wow, fantastic variety of cuts! Ain't it neat what a variety you find out there? #19 is what they call paint wood. Got some nice mossy/plumy wood casts too. I'm clueless on #17. New type for me. #16 is freaking awesome, more cast than strictly wood replacement, one of the neatest pieces I've seen from there. #7 might be pocket rot wood if cut the other direction. #8 I'm thinking palm root too and that other palm just may be fern bud of some sort. As i've said, lots of strange wood specimens down there and seems you scored a bit of everything. Great pics. keep'um coming.....Mel

Hey Mel, can you please spend a minute explaining the difference(s) between shrinkwood and rot wood?
Thanks.
Hope you and Sharon had a nice Christmas!

Thanks for the ID help, Mel! I've heard the term paint wood, but never seen examples, very cool. I've got a piece of #7 left, so I'll cut the other direction and see what it looks like. There's a ton of different material there! I've got a bunch of bigger pieces I'm really excited to cut. Hoping to get over to HankRocks tomorrow, so he can cut them on the big saw. I'll post some pics when we're done. Looking forward to the answer, of Bob's definition question. |

Bob, As I understand it, shrink wood is petrified wood that was first totally petrified While in various stages of decomposition, then shattered by pressure into breccia and then resealed with additional chalcedony. Pocket rot wood was decomposed while still unpetrified wood leaving voids. Those voids were then refilled with chalcedony and in some cases appear even with fortifications in the filled pockets. That's why filled in examples often look like dino bone and explains the other common name "dino bone wood". What's cool at George West is, you find examples of pocket rot wood with hollows often filled with tiny quartz crystals, where the chalcedony did not completely fill the rotted out pockets in the original wood. Those examples show you exactly how the pocket rot wood formed. Sharon had me drag home one of those for her garden. Clayton as even brought in one or two from the Rio Grande gravel where they also occur. Also, a lot of the George West wood is in limbcast form. Looks like wood on the outside but the inside pretty much totally decomposed, leaving no wood pattern, and was filled in with various forms of agate....Mel
PS: If you google "hexagonally fractured petrified wood" you will find an excellent article on how shrinkwood is formed. he correct scientific term is the Hex fractured wood. Shrinkwood is just a nickname.

I am sure the pictures he posts will include my favorite of the ones we cut. A nice blended pastel colored piece of wood. Would post a picture myself but will defer to Jeremy's superior photography skills.
