A closer look at a gold flake


Jeff Pike

Recommended Posts

Every so often I will take a closer look at flakes and nuggets under the scope... Here's a small end of a .3 gram flake from Nevada on a trip in '06...Note the fold - it isn't visible to the naked eye and I thought this was well worn when I found it in a small wash...

Cheers!

Jeff

Does anyone know what the symmetry of the triangles indicates?

Also it would be great to see a comparison of close ups taken from samples from different locations. Then we could perhaps make assumptions on formations? Or has that type of work been performed already?

Great pics anyway. Thank you much!

Gold commonly crystalizes in an Octagon shape (like two pyramids, one rightside up, the other upside down, attached at the wide base - see drawing)

The triangles reflect the triangular faces of the crystal.

I have also included 2 photos of gold from California which show the same triangular faces.
