.... Ferrobustamite, ideally Ca 5 FeSi 6 O 18 , occurs in some deposits associated with ilmenite granitoids. 3. Some scheelite skarns, characterized by the assemblage grossular-hedenbergite, are also associated with ilmenite granitoids. 4. Auriferous skarn deposits tend to be associated with magnetite-bearing...
