Encyclopedia
Homilite is a borosilicate mineral belonging to the gadolinite
group of minerals with formula Ca2(Fe,Mg)B2Si2O10.
It occurs as brown monoclinic crystals within feldspar
masses in pegmatite
and was discovered in 1876 in Stoko island, Langesundfiord, Norway
. The name is from the Greek
for to occur together, in allusion to its association with meliphanite and
allanite
