Histograms showing the size-frequency distribution of pyrite framboids at Panjiazhuang section. MD = Mean diameter of the framboids (μm); SD = Standard deviation of framboid diameters within a single population; n = Number of pyrite framboids measured in each sample. Each histogram corresponds to the samples marked from a to e in section column of Fig. 10, and each suggests the deposition under dysoxic conditions
