N2 - The progress of ordering of Cu+ and Pb2+ in synthetic hammarite, Cu2Pb2Bi4S9, has been monitored by the form and sharpness of satellite reflections in electron diffraction patterns and by high-resolution transmission electron microscopy (HRTEM). The results of annealing experiments indicate that in nature intermediate compositions in the bismuthinite-aikinite series consist of compositionally well-ordered polysome strips, which, depending on the initial composition and the cooling rate, may remain as disordered intergrowths (stacking disorder), form ordered intergrowths, or fully order into the supercell minerals. -from Author
