Abstract

Chamosite has been identified as a regular member of the suite of minerals constituting the Lower Ecca shales in Natal. In this deposit, chalybite, Fe-chlorite and illite are all found to be secondary to the chamosite component which serves as the principal mineral host for iron, even in beds containing as little as 2·25% Fe. Aspects of composition, fissility and origin are discussed.
