  1. 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."​

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

  3. 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.

  4. #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.
