具有沉积条带的中全新世盐沼沉积物的有机质δ 13 C和C/N比值揭示了粗粒和细粒沉积物之间的细微但显著的差异。这些都是一致的调查结果，从季节性采样的现代粉砂，并与解释，在物理和孢粉学的理由，细颗粒和粗颗粒的组件作为暖季和冷季存款，分别。控制被认为是有机物质供应的性质的季节性变化。
Bulk organic δ13C and C/N ratios from mid-Holocene salt-marsh deposits with sedimentary banding reveal subtle but significant differences between coarse- and fine-grained deposits. These are consistent with findings from seasonally sampled modern silts, and with the interpretation, on physical and palynological grounds, of the fine-grained and coarse-grained components as warm-season and cold-season deposits, respectively. The control is considered to be seasonal variations in the character of the organic matter supplied.
