What are chlorides in mineralogy ?

Chlorides : definition

Chlorides constitute a subclass of the class of halides, a strong mineralogical class of around 150 mineral species whose common feature is the presence of halogen ions : Cl- (chlorides), Br- (bromides), F- (fluorides) and I- (iodides), bound to cations.

Chlorides are scarce in terms of number of species, but some are extremely widespread and economically essential, such as halite (NaCl) or sylvite (KCl)
