Iron-bearing Oolites and the Present Conditions of Iron Sedimentation in Lake Chad (Africa),formation. The present chemical conditions lead to a scheme of iron behaviour in which colloidal or adsorbed iron from the solid load of the incoming rivers (94000 tons reactive iron in 1970–71) is separated from kaolinite, which becomes unstable in the lake, and forms a coprecipitate with silica.

,Diagenetic Pyrite and Associated Sulphides at the Almadén Mercury Mine, Spain, as a constituent feature of the “Criadero Quartzite”. The pyrite crystals are built up of a macromosaic nucleus surrounded by a diagenetic cortex. Framboids of the nucleus display frequently a mutual orientation, a structure which is unusual in “Rogenpyrit”. The cortices display different growth ty
