No they don't

Explanation:

Only those minerals are put in silicate group which have #Si# (silicon) and oxygen combined in their chemical formula. For example

#SiO_2 -># Quartz

#Fe_2SiO_3#

#Mg_2SiO_3 -># (Olivine)

Carbonate have carbon and oxygen. For example #CaCO_3# (calcium carbonate)

Halides have combination of salt forming elements of 7th group (#F#, #Cl#, #Br#, #I#) with other elements. For example #CaF_2# , #NaCl# etc

Sulfides have #S# (sulfur) with other elements like #ZnS#, #PbS#

Conclusion
Only Silicates have silicon.

hope this helps thanks
