Hand sample wishlist
Dear readers,

Here's a list of the samples I'd really like to have to show my students examples of the processes we discuss:
- A lava pillow (maybe a pillow basalt). Fresh would be best, so I could show the outer crust of obsidian, and the inner basalt. An ancient pillow would be second best.
- Boudinage. A nice hand sample of boudinage, maybe a granite dike in a shist? Or a sandstone stratum within a shale matrix? I feel like I should already have one of these, but I don't... All the good local examples are too big.
- Flame structures/ball-&-pillow soft sediment deformation.
- A komatiite sample.
- One of these. (Eubrontes track with radiating mudcracks, featured this morning on ReBecca's Dinochick Blogs)
If not, please alert Santa that I'd appreciate him filling my stocking with these goodies,

I know we have some 2" core in the warehouse with nice soft sediment deformation. I don't know when I'd get it up to No. Va. and I'd either have to go out and get a piece not in the State repository or wait until we toss some.
Mighty kind of you to even consider it. Like I said, I'll be happy to pay shipping, provided it's not taking it away from anyone down there! :)

There are some photos of ball and pillow structure in this thread. though, the structures are probably a bit large to ship.

Ooops... wrong thread. It is this one.

The Fossil Forum is the worst forum on the net. Don't waste your time. They steal your pictures and research and post as their own
