Another ugly green rock

in #geology5 years ago

In early November, we picked up another massive collection. In the collection was this ugly green rock.

After careful examination though, I noticed fine crystals, cleavages, and blue Chalcedony.

Here is a very nice olivine crystal. Unfortunately, the 2D picture doesn't show the exquisite dimensions of this beautiful crystal.

As Imentioned there are some really nice cleavage crystals as well.

These are incomplete olivine and chalcedony crystals that are riddled throughout the specimen.

Then there is the occasional blue chalcedony deposits that have an interesting contrast.

I'll enjoy going over this piece with my stereoscope on days when I'm bored.
