Reference information

Comments Nakhodka includes 2nd and 3rd Vesenny and Malysh (Volkov and others, 2006). This is distinct from Nakhodka associated with Andash in Kyrgyzstan. Supergene enrichment of copper ore is widespread (Volkov and others, 2006). Cu/Mo = 125, Cu/Au = 33500, Ag/Au = 8 (Spikerman, 1998).
