In copper-rich ores (7.9% Cu and 1.4% Zn), replacement of the primary ore by chalcopyrite has obliterated most of these textures and produced fine chalcopyrite-tetrahedrite-pyrite intergrowths. The textures clearly indicate the genesis of these ores but they impose a practical problem in recovery of the metals.
