Shiny, iridescent and striated #Chalcopyrite crystal cluster found deep inside a large mass of quartz, #Fossicked from #MineWaste at Wheal Clifford, Gwennap, #Cornwall
-
We like to think this type of clean geometric minimalism is 'modern', but humans will have been influenced by these shapes since before we were human.
Cubes of #Galena #Fossicked from #MineWaste at East Wheal Maid. I found an approx 5cm thick section of druzy quartz vein, with lots of mineralisation present, which you can see here - plenty of #Chalcopyrite and #Sphalerate as well.

CW: fossicking in cornwall (chalcopyrite mix)
A dense layered mix (from top to bottom) of dark red bubbly #goethite, silver crystalline #arsenopyrite, golden yellow #chalcopyrite and lighter red country rock with minor clusters of green #chlorite throughout. Fossicked from #minewaste at Wheal Fortune (Great Consolidated Mines), Gwennap, #Cornwall.
This is a typical mix of Cornish mining minerals. You don't want to drop this one on your toe, it's really heavy for it's size.

CW: fossicking in cornwall
Chalcopyrite fossicked from mine waste at Great Wheal Charlotte in Cornwall. This is the main ore of copper, and so presumably the main "pay dirt" back in the 1800's. I thought the blue and red flecks might be a secondary mineral, but more likely to be the iridescence of the metallic chalcopyrite itself. This composite image was made by using Hugin software to stitch together images from a cheap USB microscope. #Cornwall #MineWaste #Chalcopyrite #Mineral #Fossicking
