Trace Elements in the Altered Zones of Certain Kuroko Deposists (IV)

A Consideration on the Diffusion of Heavy Metals in Wall Rock Alteration

Abstract

The problem of material-transfer in the course of wall rock alteration is discussed in relation to diffusion. The actual features of distribusion of the heavy metals such as lead, silver, chromium, nickel, and vanadium were compared with the theoretical features, and it was determined that solute diffusion may be most important in the transfer of elements.
The rate of the migration of elements in some geologic environments is also discussed.
