We decided to do some geode hunting. I had learned enough to know that geodes can sometimes be found in lime or caliche, so off we went to the local caliche quarry and this is what we found.
This rock contained many small geodes.
More rocks (quartzite?) contained small crevices filled with crystals.
I also found this beautifully marbled rock (which I now think might be brecciated pink opal) that we tried to remove from the rock wall but to no avail. After picking at it for a while, we left it right where we found it, to be mined away some time, or, if we are lucky and no one touches it, maybe the weather will loosen it further for us to dig out next time.
Also found some rocks which I looked a little like jasper, but I don't think it is hard enough to be. A friend said they looked opalized.
It is nice to know that we might have opal around here.
Found close to Los Tambos, Cayo District
