I couldn't resist posting a couple pics of the most awsome chunk pet wood ever found in East Texas. Virgil has seen this piece too.The first pic is of the exterior witch is beautiful itself.
The next pics is of the interior
The last pic is a close up of the interior.
The best guess I can make to explain this specimen is after the wood was completely petrified a hollow was left that was later filled with agate that slowly oozed in and hardened as it entered.

Tom, I haven't really measured it but if memory serves it's about 1 1/2 foot wide at the end with the tube agate and about 2 1/2 foot long and 6-8 inches thick. The rock formation where the pet wood is found in Texas is called the Catahula Formation and is mad up primarily of sandstone. In places this sand stone was deep enough to meet high temps, pressure and hydrothermal activity and the sandstone was transformed into blue to purplu opalized quartzite. This same hydrothermal activity gives us the wonderful agatized and opalized petrified wood that I love to collect. Hint, when hunting pet wood in East Texas look for outcrops of the quartzite as the abosolutely best material will be found there.

Rob,
the outside of the material looks like typical Texas/Louisiana Petrified Wood but the inside is fabulous. The result of the petrification could be due to worm holes actually getting filled with Silica that hardened into Chalcedony. Most of the Petrified Wood found in western Louisiana and the neighboring Texas area has worm holes in it. But thy are generally voids in the material, not filled with silica. Great find and thanks for sharing it with us.

Hi Rob:
Your wood with agate bubbles is very similar to one of my pieces of Florida coral. Water with dissolved silica seeped into the coral and evaporated - leaving small deposits of the silica behind.
This picture is looking at the top of the coral where the silica-laden water seeped in creating downward forming bubbles to evaporate - leaving elongated cones over a long period of time. Exactly like stalactites in a cave.
Your wood had the same process, only the silica-laden water entered the cavity in the wood more from the side, so the agate formed along the side instead of straight downward stalactites. Basically your stalactites formed at the side instead of from the top. But the tubular structure of the agate jumped out at me resembling my coral piece.
Beautiful wood you've got there!!

Hey Rob!
Did you finally talk that farmer out of that piece? Yea, I've seen that one. The blue tube agate is gorgeous, and definitely a rarity in that area. Good thing you got dibs on it first, eh?
