Trace Elements in the Altered Zones of Certain Kuroko Deposits(V)

Distribution of Copper in the Altered Zones of the Yamabuki Deposit, Hanawa Mine

Abstract

Altered zones are developed around the Yamabuki Deposit of the Hanawa Mine, Akita Prefecture.
Copper contents rise logarithmically from the outer to the inner parts of the zone, and the distribution behaviour of copper is similar to that of heavy metals in the altered zones of several mines indicated in previous papers.
Close correlation of copper to both silver and lead is pointed out.
