What does "sediment based" mean in the geological language? I had no luck finding this concept with respect to VMS deposits and their host rocks, or is that you meant? There are three main categories of VMS deposits: 1) Felsic volcanic hosted (50%), 2) Mafic Volcanic Hosted (30%), and 3) Mixed Volcanic/Sedimentary Hosted (20%).

<<What does "sediment based" mean in the geological language?

Copper-zinc massive sulphides occur in two principal geological settings: volcanic (both mafic and felsic) rock-dominated areas (TG, Kidd Creek...) and sediment-dominated areas (Windy Craggy, Granduc...). The later are a mix of volcanic rocks and sediments where the sediments are dominant.
