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)
I've been a good boy this year. Anybody got any spares they want to trade for some nice Skolithos-bearing cobbles? (...or something else we've got a local supply of?) I'll pay shipping!

If not, please alert Santa that I'd appreciate him filling my stocking with these goodies,

Callan

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.
