The metasomatism of the Modum cobaltiferous fahlbands is examined and it is concluded that a process called "degranitisation" has taken place. The possibility of diffusion during metasomatism is second main subject of the paper; it is concluded that diffusion most probably is without any importance as a means of transport.
