PostPosted: Aug 03, 2018 19:56    Post subject: Collection Macros  

Got some macros of pieces I've collected myself only. Iphone 4 with loupe as macro lens so don't judge me haha! I think they came out nicely. Most pieces are calcite or fluorite from Columbus, Ohio rock dumps from quarries. I also have a lucky find from my birth state of New Mexico, at the Bingham Mine. Two other finds came from Mexico and Morocco while on vacations.

Hi Oliver,
The first three Alum Creek fluorites look like calcite to me. Hard to tell from the photos, but the first one appears to have rhombohedral cleavage; second looks like a complex parallel growth of calcite scalenohedra; third is hard to decipher but may be a "nail head" calcite crystal.

OLIVER, I agree with BOB C. I would not be surprised if all your Alum Creek "fluorites" turned out to be calcite. Small calcites can occasionally cleave giving an impression of being a small fluorite crystal; I am just not sure on some of yours. And if it comes from the bike path, it would be fill from another (quarry?) locality.

I would like to see a picture or 2 of the whole specimen of your quartz photo showing the "scepter". That seems very unusual for that locality.
BOB

Hardness test of 4 after my tests, That's why they are so interesting to me; I wonder why their structure changed, I concluded that it had to be Fluorite. Thanks bob!

Bob Harman,
I will post a few pictures of the geode I collected. I also thought it very strange to be in the river. I almost thought it was a discarded geode someone else collected or lost from another locale, however it wasn't cracked open yet.

Hi, again--can you tell me how you tested the hardness on the Alum Creek fluorites?

OLIVER, Your last 3 photos almost certainly show a Mexican geode of the type I have pictured. These were marketed as Rock Candy Geodes at the 2007 Tucson show. They are quite similar to yours with starburst like groups of small sceptered quartz crystals. I have the example pictured in the poster.
Unless there are other very similar examples definitely associated with the Olentangy River Ohio locality, finding your example suggests it was discarded by someone in the past. Look around in that area again and maybe you will be lucky with additional finds!
BOB

Bob Carnein, I first tested the very tip of the crystal with my fingernail and it left visible scratches on my nail, following up I used a copper plated penny and found that it also scratched the copper. Finally I took a carbon steel knife and found that it scratched very easily on the fluorite. Combined with the fluorescence and the fact that the other crystals in the same rock dump were easily distinguishable as calcite with dog tooth spar formation, I drew the conclusion that it was Fluorite. I hope my hardness test was satisfactory.
