Cumengeite from Penpol smelter slag locality, Penpol, Feock, Cornwall, England, UK
Small specimens of Cumengeite on slag from the Penpol smelter and associated dumps.
I've not managed to get a single good photo out of all of these; unfortunately the crystals are just too small for my kit to focus on well.
- #1 - Occurs alongside an unidentified green mineral which is probably Mammothite. Unfortunately, my microscope just isn't good enough to get a good image of these, even with stacked images.
- #2 - a micro micro! While this piece does have some nice crystals, extreme magnification is required - the entire specimen only around 6MM long and the crystals are certainly sub MM.
- #3 - a slightly bigger micro, with some good crystals.
- #4 - a nice micro, some white crystals which may be laurionite.
