#Hematite is also found on the island of Montreal -here associated with alkali-rich mafic magma intruding into limestone. The Francon quarry was primarily a source of building stone.
In the MinDat photo by Chris Emproto (sampled by Steve Chamberlain) the hematite is on Dawsonite*, NaAlCO3(OH)2

Over two billion tonnes of iron ore have been mined from the Labrador Trough of Quebec and Labrador over the last 70 years. The paleo-Proterozoic sediments have been variably metamorphosed (you can see the bend in the southern part of the belt caused by the younger Grenville orogeny). Much of the direct shipping ore is dominated by the mineral #Hematite.
The steel of your lunchtime knife and fork may have come from the Trough!

Go Hematite!
It’s my son’s favourite mineral. It also gets a geobiological vote, as banded iron formations may have been produced by metabolising microbes over many millions of years, beginning billions of years ago.

Haüyne, formed in magma chambers, is pretty, blue & can fluoresce. But electrically conductive iron-ore hematite is an absolute giant of art history, used as red ochre, going back at least 164,000 years to Pinnacle Point Caves! Also called Venetian, mars or English red.
Vote hematite! #MinCup25

The haüyne has my vote in this round. I have a weakness for blue, though the allure of #MartianBlueberries hematite is strong...
The pictures seemed to be missing from the original post, so I attached pics of #hauyne and #hematite to this post.

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.

Sanidine vs Hematite (planetary science edition)
While plagioclase is the dominant feldspar on Mars, high concentrations of sanidine were measured in the Windjana drill sample by Curiosity in Gale crater but it is present in other drill samples.
Hematite is a common mineral on Mars but is particularly abundant in a feature called Vera Rubin ridge at Gale crater. The presence of gray hematite in one sample suggeste hydrothermal precipitation.

#Hematite! A few polished “Tiger Iron” or banded iron specimens I have were not photographed yet, so I’ve gone to searching Flickr and found this beautiful piece also featured in a 2012 article on research with early RNA on hematite/iron being a catalyst for organic developmental enzymes! So I’d suggest and favor a vote for Hematite in #MinCup25 today. Article here: https://arstechnica.com/science/2012/06/adding-iron-is-like-giving-early-rna-enzymes-steroids/

@ombialik Agreed! I have at least 4 forms of Hemitite in my collection. I find it fascinating. Between #Hematite and #Sanidine there is no contest for me so I already voted. Thankfully over 250 folks agree with me on the vote. Anyone can vote in any daily contest. See posts with more information about the minerals by clicking their hashtags. And of course follow @MineralCup #MinCup25

Iron-rich hematite, commonly found in rocks and soil, turns out to have magnetic properties that make it a promising material for ultrafast next-generation computing. This finding comes from researchers from the Lab of Nanoscale Magnetic Materials & Magnonics.

Riche en fer et communément présente dans les roches et le sol, l’hématite s’avère posséder des propriétés magnétiques qui en font un matériau prometteur pour l’informatique ultrarapide de nouvelle génération. C'est ce que des scientifiques du Laboratoire des matériaux magnétiques nanostructurés et magnoniques ont récemment découvert.

Not one of mine, but a photo I made of a friend's specimen - amazing spherical #Hematite ("kidney ore") inclusions in water clear quartz. Some of the metallic spheres are split, so you can see how they grew from a tiny dark red core. Found in #MineWaste at Botallack mine, #Cornwall.

#WeekendReading Han et al. on the slightly mind-banding concept that authigenic #hematite (early diagenetic) has similar rock magnetic properties to detrital hematite.
