GeneralGreenalite locality
9th Sep 2014 05:25 UTCJamie Cheshire
La Unión Mine, Cartagena, Murcia, Spain
The specimen is fine-grained, massive greenalite, with a little galena included. No "La Unión Mine" is listed for Cartagena or the town of La Unión. Where might this have come from?
Thanks much!

La Union is the name of the city .
I posses a piece of greenalite from "corta(mine) San Valentin" La Union.There have bin many mines before.
Best regards,
André.

at http://tuplaneta.es/docs/LaUnion.jpg you can find a map with the mining concessions at the Sierra de Cartagena. There was a "La Union" concession near the city of Cartagena, in section C4. No idea if the concession was ever mined.
Cheers,
Stefan

My opinion is that even if there was a "La Unión Mine", the name "La Unión" is used generally for the district. Greenalite is found literaly everywhere in the Cartagena - La Unión mining district . There are millions of tons there!. The best greenalite specimens are included in quartz, forming deep green to dark green prase quartzs to 7 cm.
Regards
Iván
