Sand fom Þorlákshöfn, Iceland, under the GIGAmacro lens
Posted by Callan Bentley
I think this one of the most fascinating batches of sand we’ve yet had the pleasure of macro-GigaPanning:
So much igneous goodness hidden in those grains, collected from a beach on the south of Iceland…
The image was made by Robin Rohrback-Schiavone (my student at NOVA) as part of the Mid-Atlantic Geo-Image Collection (M.A.G.I.C.). The sand sample was donated by my colleague Beth Doyle. Thanks to both of them!

If we find a gemstone do we get it?
Reminds me of going thru the gravel (glacial outwash) at the local pits when I was a kid. Except the sedimentary third isn’t represented.
any way to put a scale on those sand photos, Callan?
There’s a petri dish in every one that is 9 cm in diameter. But in terms of auto-sizing scale that is on the screen at every step of the exploration, we do not yet have that, but hope to someday.
