Jessica's Micro Collection

9th Apr 2011

I do not know if this is of interest to anyone, but I thought someone might be interested in the distribution of mineral species in Jessica's micromount collection. This does not include any pieces she has which are thumbnail or larger. The following table shows the number of distinct species represented by Dana category. For example, she has 20+ wulfenites (she obviously likes those), but they count as only one in the following table.

As she acquired pieces, she did not do so with any consideration for what she already had, which Dana categories she does and doesn't have represented, or anything else beyond liking the specimen. She she got what she liked and ended up with this so far:

I am by no means very knowledgable with respect to minerals. But I did find some interesting trands here. For example, she seems to like phosphates.

Thanks for looking.

I think this way of trying to put up a random(?) gathered collection into a systematic table, just say something about what mineral-groups have more aestetic members than others. Or it could also say something about what minerals that was possible to find and collected at localities visited... But as you write this is acquired specimens, so i think it's a way to illustrate distribution of aestetic minerals in various groups - offered for sale... And I don't know if that is important or interesting?

The question is do you think Jessica will move into serious systematic collecting - and then what will she find interesting? :-)
I have some absolutely not beautifull, but rare minerals that can contribute to a general systematic micro collection. And can even contribute with some type locality minerals if getting TL minerals would be of interest.

Anyway, what is most important is that Jessica is collecting micromounts! And I would be happy to contribute to her collection :-)

How Can I see Her collection in internet?
Thanks

Peter, thanks - we have now "talked" via PM.

Farid, we have not photographed them yet. There are at least 300 pieces. I am still experimenting with micro photography. My success rate at this point is not something I would post to mindat.
