@stommepoes @DrJosephGraly Having to google/ddg what "REE" means for people outside the field is not going to prevent breakthroughs from happening

@RockhoundRich One of the exercises I give students is let them read media articles about "Rare earths!!!!111" when it's all about lithium and cobalt, and tell me if they can spot what's wrong

@kmgoodenough It's useful to remove ambiguity, but no such ambiguity exists here. I'm thinking that "REE" has advanced to the status of a proper word, and we can stop repeatedly defining and redefining. Just like we don't define any other jargon word. We assume people know.

@RockhoundRich Wait until we get to the rabbit hole of whether scandium and promethium are REE

Here’s an older SEM image of spmm8 (the 8th micrometeorite I’ve found). And a new colored closeup which roughly represents the area inside the red rectangle.

@MineralCup Webmineral and Mindat both list the simplified #Vivianite formula:
(Fe2+)3 (PO4)2 · 8H2O

Wikipedia, however, lists the formula differently:
(Fe2+) (Fe2+)2 (PO4)2 · 8H2O

...and you might be thinking: why on Earth does Fe2+ show up in 2 different places?

@Sarah_Lambart @LJElkins I don't know how it works, but have you tried asking? Get a group of professors writing a business case, saying it will be used for this many courses and that many students with an average cost of x dollars per year per student or something?
