Sphalerite ZnS ( primary ) alters to secondary hemimorphite Zn 4 Si 2 O 7 ( OH ) 2 . H 2 O, smithsonite ZnCO 3 and manganese-bearing willemite Zn 2 SiO 4.
It has been replaced by smithsonite and hemimorphite in order to distinguish it from the pinkish mixture of zinc oxide ( ZnO ) and iron ( III ) oxide ( Fe 2 O 3 ) used in calamine lotion.
