The chemical and isotopic characterization of the pyrite to pyrrhotite desulfidation reaction across the metamorphic gradients of a metasedimentary basin

Data S1 includes SIMS multiple sulfur isotope (33S, 34S, 36S) of pyrite, pyrrhotite and chalcopyrite from the Pontiac Subprovince metamorphic zones (biotite, garnet and staurolite). Data S2 includes LA-ICP-MS trace element analyses (including errors and detection limits) of pyrite and pyrrhotite from the Pontiac Subprovince (biotite, garnet, staurolite, sillimanite metamorphic zones). | External Organisations Université Laval; Université du Québec à Chicoutimi | Associated Persons Bruna Coldebella (Creator); Isaac Siles Malta (Contributor); Carl Guilmette (Contributor); Guillaume Barré (Contributor); Georges Beaudoin (Contributor); Dany Savard (Contributor)
