Abstract

"The occurrence of pyrite crystals embedded in the exines of spores and microplankton is described from some upper Palaeozoic sediments of Britain. Solution of the pyrite produces a variety of cavities which reflect the state of aggregation of the mineral. The morphology of these cavities or pyrite relic structures is described in detail and a classification into simple, cribrate and faviform structures is proposed. The form and distribution of the pyrite crystals favor an organic origin, possibly bacterial."
