There are repeatable quests inside most of the Cataclysm 5-man Dungeons which allow a buff to be applied to your party when you submit the proper keystone to the quest object.

These quest giving objects have the daily blue “!” above them and turning in the right keystone for the zone will give a buff (which is limited to that 5-man).

It’s currently believe that you need the appropriate Archaeology skill level required to loot the keystone, in order to turn in the quest (Example 450+ for Tol’vir Hieroglyphic.)
