Abstract
This descriptive paper identifies three widely occurring textures designated as 'watermelon', 'dusting' and 'bimodal' that characterize the replacement of original Fe-bearing sphalerite by an aggregate of chalcopyrite and low-Fe sphalerite as an integral part of the mineralization process. Replacement probably predominates over alternative modes of origin for small chalcopyrite blebs in sphalerite from most vein and sea-floor massive sulphide deposits that formed in the 200-400oC temperature range and that have not been subsequently subjected to higher T. Sphalerite from the epithermal Ag-Pb-Zn deposit at Creede, Colorado, displays a rich variety of features ("bead chains') that are primary crystal dislocations decorated by exsolved chalcopyrite.-J.A.Z.
