Geopuzzle #13

Whilst I struggle to cope with the suddent onset of dementia in my beloved but aging laptop (which causes it to switch off 5 seconds after I switch it on, before it even gets to the stage of booting up), here’s a simple one for you. How big is this piece of muscovite?

    Smaller than Muscovy.

    On my screen, it measures 0.021005 Smoots.

    Hmm… Don’t know nothin’ ’bout mineralogy, but based on this image and this image, I’m going to guess that it’s a very small piece of muscovite, no more than a few millimeters.

    Bigger than a breadbox.

  5. cope says:

    1″ X 1.3″

  6. Tegumai Bopsulai, FCD says:

    I measured it very carefully. It is 394 pixels wide and 325 pixels high.

    4.6cm east to west.

    a few hundred microns?

  9. Greg Laden says:

    I’m guessing it is a hand sample. So about the size of your hand.
    On the laptop: Sounds like mine. May need new battery.

    Thinking about it some more, the real answer is, “It’s muscovite, who cares?” ;)

  11. hmmmm…. well, something for scale would be nice (Im kidding!) but I’m guessing that based on all the books of muscovite Ive come across that this might be quite large. If it was a very small piece of muscovite it would be more transparent, you can see from the photo that it is a nice specimen with good cleavage on the ‘C’ axis. I really don’t know and willingly accept any answer you say ;)

    The cloud forest growing in the middle is a big clue.

  14. Divalent says:

    Hmmm, looks like activity died up here. To move things along, in addition to my guess above, I’ll also claim any other size not claimed by anyone else. (But won’t truly feel I won if my first guess is wrong.)
    So, how big is it, eh?

    Sorry, I didn’t mean to leave you in suspense for so long… The answer is now up.
    Divalent is, of course, technically the winner, but his devious logic games have no effect on me.
