  2. New Preprint Alert!

    I'm excited to share my latest research: "Modern Vivianite at the K–Pg Boundary, New Jersey Coastal Plain: A Redox-Driven Proxy at a Legacy Stratigraphic Interface."​

    Did you know that Vivianite can appear on the iron coffins or on the corpses of humans as a result of a chemical reaction of the decomposing body with the iron enclosure?

    Congratulations #dioptase! Your Queenly emerald glow has outshone the Lady of Darkness’ gothic vibes. Farewell #vivianite. May you return from your underworld of darkness to rally your fans next year.

  5. Once again, the Emerald Queen of the Desert faces off against the Lady of Darkness.

    #Dioptase, also known as the Emerald Queen of the Desert, is rare and forms in arid conditions. With its glorious emerald to teal-green vitreous and translucent crystals, dioptase is popular with mineral collectors.

    #Vivianite is a ferrous-iron-phosphate mineral found in organic environments and can grow on decaying wood, bones and other organic material. It is a colorless mineral, but oxidizes easily changing its prismatic and flattened crystals to a vivid dark-green to green-blue.

  6. #MinCup24 R2M4: #Dioptase versus #Vivianite

    Dioptase is rare and has glorious emerald to teal-green vitreous and translucent crystals. Vivianite can grow on decaying wood, bones and other organic material, much to gothic delight.

    If this match feels familiar, we saw this same battle in Round 2 Match 3 of Mineral Cup 2023. But every year are new voters with new motivations! Which will you choose this year?

  7. is a second chance for (which lost out to earlier). Ringwoodite has the chemistry of olivine (Mg2SiO4) but the crystal structure of spinel (MgAl2O4).

  8. Okay, #vivianite is cool (and in the lead, I see) and all. But #spinel! Older than earth! That got me. Like we expect that from quartz and diamond and what's that other fucker, but spinel! It seems so omnipresent yet unassuming... and bam the more you know.

  9. #MinCup24 Round 1 Match 8: #Spinel vs #Vivianite

    Spinel makes gems and has some interesting geophysical stories to tell but I have to give the art vote to Vivianite -a pigment in the gorgeous blues of the Pacific NW peoples (including Tshimshian & Haida) & some European medieval, through 18th century paintings, Māori tattoos, Wiru masks from PNG.

  10. #MinCup 24 ROUND 1 MATCH 8: #Vivianite vs #Spinel

    Is it the popular Lady of Darkness formed by chemical reactions in the presence of decomposition, or is it the ubiquitous and gemmy mineral found everywhere from the mantle to meteorites older than earth?

    Which will you choose?

  11. After a close race that flipped back and forth many times over, congratulations to #Dioptase the Desert Emerald for making it into #MinCup23 Round 3!

    Better luck next year to the spooky yet charming #Vivianite

  12. #MinCup23

    Both #dioptase (Cu6(Si6O28*6H2O) and #vivianite (Fe3(PO4)*8H2O) contain crystal water, but vivianite has more. Vivianite is much softer (Mohs 1,5-2) than dioptase (Mohs 5), and at least Cu keeps its valence when exposed to air.

    Vote stable and green! Vote #dioptase!

  13. #MinCup23 Round 2 Match 3

    It’s the emerald Queen of the Desert #Dioptase versus the dramatic Lady of Darkness #Vivianite. Both are gorgeous, but who will be gone with the wind?
