Fig. 2: Representative pyrite texture in the Chang’an gold deposit.

From: Release and re-enrichment of invisible gold in arsenian pyrite promoted by coupled dissolution-reprecipitation reactions

Fig. 2

a–f BSE images of pyrite comprising arsenopyrite-, galena- and void-rich core and inclusion-free rim. Pyrite quartz and native gold are wrapped by zoned pyrite in (d). The pyrites from proximal (a, f) to distal (b, c) quartz-ankerite veinlet show a decline in arsenopyrite inclusions and thickness of pyrite rim. The locations of (a–f) are shown in Fig. 1c, d. Alt alteration, Ank ankerite, Apy arsenopyrite, Au native gold, Ga galena, Py pyrite, Q quartz, Ser sericite.
