Some more minerals I got on my recent trip! A bunch of these remind me of other more benign minerals, but actually contain lead and/or arsenic. #rockcollection#mineralcollection#minerals#dioptase#mimetite#conichalcite#celadonite#linarite#barite#hyaliteopal#lemonopal#opal#minerals

Dioptase (turquoise crystals) and mimetite (yellow crystals).
Conichalcite and celadonite (both are green).
Linarite (blue) on barite.
Hyalite opal (green fluorescence) and lemon opal (yellow fluorescence). No lead or arsenic in either but at least the hyalite may have trace amounts of uranium contributing to the glow.

I don't have any favourites for this round but copper is winning a bit more because of the variety of interesting morphologies. Plus lots of other minerals (malachite, linarite, liroconite...) are formed via the weathering of copper bearing ores! #geology#minerals#science#museums#MinCup24 🧪⚒️

I wish I could do a video. The linarite is very sparkly.

malachite is a perpetual favorite but of these specimens, the linarite is particularly lovely

Linarite こちらも開拓産地にて。 べったりしがちな青鉛鉱ですが、自由な空隙があれば板状結晶の集合を作ります。 この産地は上部が金鉱床、下部が銅・鉛・亜鉛鉱床として採掘されていて、下部は著しく酸化されて二次鉱物のオンパレードとなっていました。

Holy shit just check out Steve Rust’s entire mindat gallery actually, it’s the best I’ve seen — clearly lit & sharp, fascinating subjects, beautifully composed, consistently conveying a real sense of texture. www.mindat.org/gallery-1129... (pic: linarite/cerussite/caledonite) #MinCup23

Close up of “grotto” crested by crusty oceanic pastels and opening into a bed of spiked blue linarite puffs onward into the dark.

Hey! So the different colours are different minerals. Dark blue = linarite, pale blue = some other copper mineral, and then the cream bit is just the "host rock"

A blue mineral for Blue Sky: Linarite from Roughton Gill, Cumbria, England

Deep blue, angular crystals of linarite on a cream groundmass.
