About Jasonsmithite
Jason B. Smith
Formula:
Mn2+4ZnAl(PO4)4(OH)(H2O)7 · 3.5H2O
Colour:
Colorless to light brown (indistinct color boundaries)
Lustre:
Vitreous
Hardness:
2
Specific Gravity:
2.63
Crystal System:
Monoclinic
Name:
Named by Anthony R. Kampf, Aaron J. Celestian, Barbara P., Nash, in honor of Jason Boyd Smith (b. 1977), geologist and mineral collector from Charlotte, North Carolina, USA. He found the type specimen.
Chemically a bit similar to ferraioloite.
New structure type.
Found in the east dump.
From type description:
"With H2O groups removed, the framework has a void space of 70.2% per unit cell, and a framework density of 14.5 polyhedral atoms/1000 Å3, which would place jasonsmithite among the most porous minerals."
