Yofortierite



Yofortierite
 You may remember that recently I told you we would look at other minerals which look like dead grass.  This is one.  The sample is from De-mix Varennes qy.,Saint Amable sill Varennes Quebec,Canada.  This is the type locality for this mineral.  Min-dat says its color ranges from pink to pale violet brown.




Yofortierite
It is named for Yves Oscar Fortier, Director of  the Geological Survey of Canada, whose dates  are(1914-2014)  He lived a good long life! 

Yofortierite
Mn5Si8O20(OH)2 · 8-9H2O is its formula.
It appears to me that its primary use is mineral collection.
FYI, the "dead grass" are actually crystals.
