Magnesium iron silicate hydroxide

This is magnesium iron silicate hydroxide. Apparently it has the chemical formula (Mg,Fe)7Si8O22(OH)2, although that doesn’t show the subscripts very well… The reason it is today’s blogworthy topic is that it was discovered in Cummington, Massechusetts, and as we all know, chemists like to name things after where they were discovered.

What I can’t decide is whether it is acceptable to laugh because there is a type of stone called “cummingtonite”.
