英文摘要: The vertical distribution of iron species in the sediments collected from Kuhai Lake was investigated in this study. Their Mossbauer spectra were composed of one sextet and four doublets ascribable to one paramagnetic high-spin Fe(3+), two paramagnetic high-spin Fe(2+) with different quadrupole splittings, and one diamagnetic low-spin Fe(2+) that corresponds to pyrite (FeS(2)). The distribution of pyrite was considered to reflect the climatic change during the past 2,000 years. Mossbauer spectroscopy was successfully applied to the analysis of the Kuhai Lake sediments so as to reconstruct the history of the past climate.
