taenite X nontronite on the #MinCup25 sketchbook.

nontronite will be fun to paint. taenite is impressive but very bland visually.

#minerals #sketchbook #b&wart #sciart
sketchbook page photo with the black and white pen drawings of taenite and nontronite chunks. one is a metal from space, the other is a chunk of clay. a pen rests upon the page.

This is a difficult decision. Kyanite rocks and has the Subnautica community behind it. But Taenite is FROM SPACE!

Why oh why must I choose between thou two? There are few who could swing me away from #kyanite, but #taenite is one of them. So I will (heartbrokenly) vote for the spacerock #TeamTaenite #MinCup #MinCup25

Look, since my wife is a sculptor, I’ve got nothing against clay & #nontronite is pretty neat-o. Yet, #taenite is in meteorites, shows those great Widmanstätten patterns (look like alien computer chips to my sci-fi brain!) & is a possible peak into Earth’s core. I’m Team Space Rock here. #MinCup25

illustration of four minerals: taenite, nontronite, okenite and calcite. most of them white and gray, calcite is like a crystal, taenite a metal cut in half with an interesting crystal pattern inside, oketine is like a fluffy ball, actually some tiny sharp needle-like crystal ball and nontronite is like a slightly yellow ore embedde in a rock.

kyanite X taenite.

deep in the earth versus out of this world. I'm voting kyanite. go earth!

Illustration of two minerals competing in the round 2 match 7 of the Mineral Cup 2025. Kyanite versus taenite. The first one represented here as some deep blue crystal pins encrusted on another mineral, and the second is a cut of a metallic meteorite with a cross-hatched pattern.

With a spot in round 3 on the line, the stakes are high today for Cup veteran #kyanite and first-timer #taenite.

Our analysis: Taenite can be spacey and might lose focus during match, whereas kyanite can take the pressure and keep sparkling. It has our vote! #MinCup25

illustration of six pieces of minerals in full colour: stibnite, hematite, baryte, haüyne, pectolite and perovskite. they have varied appearances going from crystals to nuggets of metal. illustrations of five minerals next to each other: chrysotile, jeremejevite, silver, sanidine and the amazing kosmochlor. they go from grey silver to deep blue and green colourful illustrations of 5 minerals in hues of blue, green and beige. They are azurite, titanite, thortveitit, topaz and kyanite, the mineral cup winner of 2025. illustration of four minerals: taenite, nontronite, okenite and calcite. most of them white and gray, calcite is like a crystal, taenite a metal cut in half with an interesting crystal pattern inside, oketine is like a fluffy ball, actually some tiny sharp needle-like crystal ball and nontronite is like a slightly yellow ore embedde in a rock.

Taenite is the material of protoplanetary cores - from bodies in the early days of the solar system that got big enough to differentiate, then blown apart by impacts. It’s a window into the inaccessible core of our own planet. Sorry clays, but taenite has my vote.

The Astro vote today has to be for #Taenite, which (with kamacite, the mineral known as ‘Sir not appearing in this competition’) forms the gorgeous Widmanstätten patterns found in nickel-iron meteorites!

While iron-nickel alloy taenite gets physics points for its meteorite origin, iron-rich clay mineral nontronite is formed in deep sea hydrothermal vents, used in pulp & paper and cosmetics and since weathering would be needed to produce it, is part of the evidence for water on Mars.

#Taenite is a major constituent of iron meteorites. In octahedrites it is found in bands interleaving with kamacite forming Widmanstätten patterns (which are all the photos!)
Taenite is a mineral found naturally on Earth mostly in iron meteorites. It is an alloy of iron and nickel.
#spacerocks
Crosshatching on a silver background you can note the Widmanstätten patterns that form a circut board like pattern across the surface. Another fantastic example of the Widmanstätten patterns that appear as etched triangular formations that are interleaved across each other. This is another example of Widmanstätten patterns on Taenite. This shows some heat stress in the center where the normally straight lines were morphed by heat/pressure stress. An excellent example of taenite with the Widmanstätten patterns that is a return to the very straight and angular patterns it produces.

This is the hardest choice for me yet -- I have to go with #taenite here because Widmanstätten patterns are my favourite material phenomena (what better collision of my materials science and astro engineering backgrounds?) #MinCup25

I'm 100% team #taenite. As a main component of iron meteorites I've studied, taenite is more than just a cool space metal. It's nickel composition and presence in Widmanstätten patterns can indicate the size and cooling rate of the asteroid core it came from! #MinCup25

voting for taenite for its nickel content!
Last time I tried to play it in online scrabble, was deemed an invalid word which was disappointing!
