Photographs showing hand specimens and cross-cutting relationships of different veinlets of the Xiejiagou gold deposit. (a) Early-stage white quartz in K-feldspar pyrite sericite silica-altered rocks; (b) early-stage white quartz sericite K-feldspar assemblages cemented by middle-stage smoky gold quartz pyrite assemblages; (c) early-stage white quartz pyrite assemblages infilled by middle-stage smoky gold quartz pyrite assemblages; (d) middle-stage smoky gold polymetallic sulfide quartz assemblages; (e) middle-stage smoky gold polymetallic sulfide quartz assemblages cross-cut by late quartz carbonate pyrite veinlet; (f) pyrite sericite silica-altered rocks cross-cut by late quartz carbonate veinlet.
