    Copper Scorpion

    My chemistry is a little out of date, but I think that copper sulfide in the presence of groundwater might react with the oxygen component of the chitin that makes up an arthropod's exoskeleton, and possibly would precipitate the copper, which might attach to the remains of the bug. That bug probably sat in a puddle of green, gooey mine leach water for half a century to reach its current state. As Bob infers, there would have been some natural battery action going on. And it would have smelled badly, plus maybe released some carbon monoxide in the process. Somewhere in the literature I once read of a ground squirrel skeleton found in a cave in Eastern Europe that had similarly been partially encrusted in copper. Pretty cool.

    ArcticDave's Legal Eagle XL

    Interesting idea. I just calculated it out for a large and blocky rectangular and untapered "wing" measuring 32'x6'x12". At 0.069 lbs. of lift (or float) per cubic foot of helium, a volume of 192 cubic feet filled with helium gas would essentially make the aircraft 13.248 pounds lighter than without the gas. I'm almost certain that Dave's wings will have much smaller volume than 192 cubic feet. The lift would lessen with altitude as the air became less dense, and would vary with changes in atmospheric pressure, and would also vary considerably with changes in humidity, as increasing water vapor increases the weight of the air in which the helium is floating. It might be wise to carry a few six packs as ballast.

    Drilled Quartz?

    That's pretty much how I'd sum it up, Greg. Those cavities result from natural processes. If the rock had been drilled by a human, even back in the early Stone Age, the holes would be round. Early man was very adept at making very round holes. I've seen early tools and beads with bored holes found at archeological digs in Judea, relics of the Lower Neolithic, and those holes were as true to the naked eye as anything I could bore on a lathe or mill. In man's quest to create more and more complex tools, boring round holes was a fairly easy first step on the long road to becoming master machinists and engineers. Gears and cams and pinions took a bit longer to master.

    Dental-Dilemma

    Ha! The poor Brits do take a beating about their teeth, don't they? I always assumed it was something in their diet (like maybe too much ale and sugared tea), but maybe it is DNA.

    Dental-Dilemma

    LowPoint, I hate to nose into another fellow's personal hygiene regimen, but I really think you should work on your flossing technique.

    Fossil find

    Really nice find. I'd always thought those vintage club mosses were smaller, but just looked it up and lepido reached over 100 feet in height. Like Adam, I'm wondering where you found it.

    Equinox gold

    Wow, what a beauty! That'll pay for gas and beans.

    Do not use magnet on meteorites

    Depending on where you were, you might have been sitting on a pile of magnetite. And yes, a camera is a good idea, and not just for still photos, but video too.

    Do not use magnet on meteorites

    You weren't by chance carrying a magnet in your pocket?

    eye problemssssss

    I wish the only droopy part of me was an eyelid. Unfortunately they haven't yet invented a universal, whole-body little blue pill. But I agree with the above comments that you don't want to mess around when it comes to anything that affects vision. Chances are it's an easy fix. I had an uncle who used to put a spot of super glue on a saggy upper eyelid, and then pinch the lid to glue a fold together. He repeated every so often for several years until he accidentally glued his thumb to his eyelid, and then he got it fixed right with a couple of stitches. Probably best to just do it right to begin with.

    Green and yellow ID Please !!

    I can't tell from the photos what the tumbled stones are (although the second one resembles a Hall's lozenge), but I sure hope they're not resting on your palm.

    That's exactly what I've been saying all along.

    Please help fro my Daddy...

    Pretty darned nice of you, Rocky. Generosity is rarer than meteorites.

    Well, gee, it doesn't appear to be cinnabar if it scratches fluorite. Thanks for that test, Jcervay.
  15. I was thinking it's similar to a thick layer of caliche in Israel, in Hevron and G'lil. Just like gold settles down up top of caliche in the Southwest, in the Middle East it is coins and Bronze and Iron Age relics (maybe heavy varieties of meteroites, too?) that settle down on top of that caliche. In hill country, that layer is cut by wadis (gulches), and you can also see older caliche layers from earlier climate cycles in the column.
