The texture and mineral composition of ore in the Dayao copper deposit. (a) Chalcocite (Cc) replacement by hematite (He) (XSR615-1); (b) pyrite (Py) replacement by chalcopyrite (Cp) (XSR-26-3-1); (c) chalcopyrite (Cp) replacement by bornite (Bn) (XSR-150-1); and (d) bornite (Bn) replacement by chalcocite (Cc) (XSR-151-1). The sample location is ZK15602 (XSR-615-1) and ZK1503-1 (XSR-26-3-1, XSR-150-1, and XSR-151-1) (see Figures 2(b) and 4).
