Native copper in a sedimentary conglomerate. It is proposed that detrital hematite reacts with copper sulfate solutions to reduce the copper and the fluids carry away the iron and sulfur.

Nice article on the type locality of #carrollite : Carroll County, Maryland and the Patapsco Mine.

A pseudomorph (false form) is when one mineral changes to another, but keeps the original form. #copper #OreCup25 #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

Voting for minerals is back this week with the new #OreCup! I am taking my art and physics applications voting scheme from the #MinCup25, but the #OreCup25 is making it hard pitting 2 strong contenders against each other in the first round! Found worldwide Copper & Galena have been used since antiquity (see the woodcut of early Galena smelting via Agricola here). Both used for pigments (as with the copper-based verdigris used in this Van Eyck).

Remember dendrites (from the Greek word dendron meaning tree)? They are tree-like minerals that form under special conditions. There is a lovely dendritic #copper sample on the upper right. Thanks Susie! More in comment 👇🏼 #OreCup25 #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

#Galena is a primary ore mineral for lead.
Nearly every car on the road today, even EVs, have a lead battery for powering accessories.
Lead batteries are the most recycled product (over 99% in the US) and overall lead recycling (76%) is second only to gold.

The Flemish masters painted on #copper as it provided a smooth surface that allowed fine detail and durability of their exquisite works, like this self portrait of Rembrandt. #OreCup25 #MinCup25 ⚒️ sci-fi 🧪 🖖🏼 scifi Geosciences #WomenInSTEM geology 🔭🪐

Naturally occurring pure copper is called “native” copper & is formed in veins & fractures by super-heated mineral-rich fluids often associated with volcanic activity. My sample shown below.

Massive #hematite later brecciated by quartz veining, From the Soudan ironstone, Ely greenstone belt, Vermilion district of northern Minnesota.
These ironstones are sandwiched between pillow basalts of approximately 2.7 billion years old.

Repost: Perovskite is found just west of Montreal in the Oka Complex; Carbonate-rich, silica-poor magma emplaced in the Cretaceous. The site was mined for niobium in the 1960's and 1970's -it's also enriched in REEs and thorium.
There’s more about perovsite at Oka on MinDat:

Today, molybdenum is one of the most common trace elements in the ocean due to oxidative weathering of #Molybdenite. But in the Archean the oceans were reducing, and molybdenum was scarce.
Other nitrogenases evolved to use other transition elements, but Mo-nitrogenase was first, and best.
Molybdenite enables the Earth's biosphere!

#Molybdenite is the primary host for the element molybdenum in the Earth's crust.
Molybdenum is part of the most effective biological molecule for nitrogen fixation (Mo-nitrogenase), which converts atmospheric N2 to a bio-available form.
The grey sphere is Mo; this complex molecule likely evolved more than 3.2 billion years ago.

I've been eaten by a grue but this match pulled me back because #azurite my beloved,,,,
Look, #kosmochlor is a space rock, big whoop. Did you miss they've also found it terrestrially? (Is it remnants of Other Space Rock? Maybe. Shhhhh.) They buried the lede that it's a #clinopyroxene: it's a *temperature and pressure indicator*. I.e., certain formations, colors, levels of occurrence, etc etc etc, say a LOT about how hot e.g. a magma was, what other minerals and ores might be (geologically) nearby, what stressors were on these rocks over time, etc.
Clinopyroxenes are, for the most part, *scientifically* valuable rather than monetarily, aiui. (#Jadeite is a notable exception.) (#Nephrite is not even a clinopyroxine!) (Freely admit I may be wrong!)
Aaaaanyway: scientifically, yes, it's super cool. Azurite is a favorite and I gotta vote for one of my favorite copper minerals. 😂🤷🏻
(Let's be real, bar a wild upset, the space mineral will win. But azurite tho. Aaaaaaazuuuuuuriiiiiiiite.)
