Pyrite framboids represent cubic close packed supermolecular colloid aggregates or »crystals», probably formed by a process of coacervation and particulation due to the reaction of ferruginous humic acid with biogenic H2S. The structures are enlarged and show morphological changes due to later diagenetic effects.
