The article describes the studies of the iron speciation (the occurrence of Fe(II), Fe(III), and complexed iron) in acid leachable fraction of deposits. The speciation of iron was diverse for deposits of different origins and was the specific "fingerprint"-marker of deposition processes. The higher occurrence of Fe(II) may be connected with decantation which has been observed for lake sediments, the majority of Fe(III) with upper flow regime erosion-deposition processes, observed for river sediment deposition during flood episodes. As verification for this hypothesis, the explanation for the iron speciation in the different river sediment samples has been used.
本文描述了沉积物酸可提取部分中铁形态（Fe(II)、Fe(III) 和配合态铁）的研究。不同成因沉积物中铁的形态多种多样，是特定的沉积过程“指纹”标记。较高的 Fe(II)含量可能与沉降作用有关，沉降作用在湖泊沉积物中较为常见；较高的 Fe(III)含量可能与上流水流侵蚀-沉积作用有关，这种作用在洪水期间河流沉积物的沉积过程中较为常见。为了验证这一假设，本文还对不同河流沉积物样品中铁形态的成因进行了分析。
