摘要

Detailed studies of pyrite framboids from degraded leaf cuticles have been carried out under scanning electron microscope (SEM) and energy-dispersive Xray analyser system (EDAX). The investigations indicate that framboidal pyrites form ire the cavities and cell lumen of degraded leaves and other plant entities under reducing conditions. They occur in clusters and as solitary spherules. The elemental analyses indicate that the carbon, nitrogen, oxygen, phosphorus, iron and sulphur are the main constituents of framboids developed on the organic substrate. The morphological characters of bacterial colonies are generally retained during mineral uptake to form framboids.
