Abstract The chemical composition and mineral inclusions in peats and the underlying soils of the eutrophic Obskoye fen (Western Siberia, Tomsk Region) are studied. The basic pattern of a change in the mineralogical and geochemical conditions at depth consists in domination of hydroxides on top of the peat deposit and sulfides at the bottom. The geochemical reduction barrier is formed at the bottom of the peat deposit. Its functioning is related to increased concentrations of U and Hg. The markedly pronounced influence exerted by sewage discharge is associated with an increase in the Na concentration in acid extracts from peats and additional accumulation of the mixture of suspended, colloidal, and dissolved forms of some metals in the boggy environment.

人为负荷下富营养化 Obskoye Fen 泥炭矿床的矿物学和地球化学特征（西西伯利亚）

摘要 研究了富营养化的 Obskoye fen（西西伯利亚，托木斯克地区）泥炭和下伏土壤中的化学成分和矿物包裹体。深部矿物学和地球化学条件变化的基本模式包括在泥炭沉积物顶部的氢氧化物和底部的硫化物占主导地位。地球化学还原屏障形成于泥炭沉积层底部。它的功能与 U 和 Hg 的浓度增加有关。污水排放产生的显着影响与泥炭酸提取物中 Na 浓度的增加以及沼泽环境中某些金属的悬浮、胶体和溶解形式的混合物的额外积累有关。
