We study nuclear effects in charged current deep inelastic neutrino- iron scattering in the framework of a X(2) analysis of parton distribution functions ( PDFs). We extract a set of iron PDFs and show that under reasonable assumptions it is possible to constrain the valence, light sea, and strange quark distributions. Our iron PDFs are used to compute x(Bj)- dependent and Q(2)- dependent nuclear correction factors for iron structure functions which are required in global analyses of free nucleon PDFs. We compare our results with nuclear correction factors from neutrino- nucleus scattering models and correction factors for l(+/-) -iron scattering. We find that, except for very high x(Bj), our correction factors differ in both shape and magnitude from the correction factors of the models and charged- lepton scattering.
