 Within disturbed and tectonized sequences, SedEx mineralization behaves similarly to other massive sulfide deposits, being a low-competence low shear strength layer within more rigid silicate sedimentary rocks.As such, boudinage structures, dikes of sulfides, vein sulfides and hydrothermally remobilized and enriched portions or peripheries of SedEx deposits are individually known from amongst the various examples worldwide.SedEx mineralization is best known in lead-zinc ore deposit classification schemes as the vast majority of the largest and most important deposits of this type are formed by sedimentary-exhalative processes.
