With realistic estimates of the volatile output from the mantle, particularly the mantle wedge, it is possible to assess the state of volatile mass balance for the mantle—comparing inputs via subduction zones with outputs via arc, mid-ocean ridge, and (possibly) plume-related magmatism. Understanding the volatile systematics of the mantle is a key component in defining its structure and evolutionary history. 

In this contribution, we focus on the noble gas systematics of subduction zones. First, we review the various methodologies of sampling noble gases (and other volatiles) using fluids and rocks in both the subaerial and submarine environments. The aim is to... 

This review has focused on the noble gas systematics of subduction zones. Although a considerable database has been accumulated on the noble gas (and major volatile) characteristics of both arc and back-arc regions, and these are summarized above, there are numerous topics which warrant further and more detailed attention. We suggest that the following list contains realistic objectives where advances can be made ...
