How to distinguish the origin of sulfides in subduction zone interface rocks?

16 June 2024 1 604 Report

If we find sulfides in subduction zone interface rocks, how can we distinguish whether these sulfides are related to crust-derived fluids or originate from the original mantle wedge? Especially when the sulfur isotope values are near 0, are there other indicators that can be used for differentiation?

Best wishes！

Petrography of sulfide mineral host rock may help in identification of fluid versus magmatic origin of the sulfide mineral.
