Geochemical evidence of pollutants from coalfired generating stations in late Pleistocene palaeosols in the Dalijia Shan, northwestern China
Surface palaeosols in two tills and a diamicton from an area in northwestern China were analysed for geochemical pollutants. Elevated levels of Br, As and Sb indicate that pollution from coal-burning and/or coal-fired electricity generating stations is delivered by aeolian transport into palaeosols dating from the last glaciation. Because the climate in the field area is sub-humid (precipitation <760 mm) the relative movement of soluble elements in palaeosols dating from early and late stades of the last glaciation is not expected to be high. The glacial and aeolian parent materials of the palaeosols indicate differences that are probably related to their source areas and to the incorporation of geochemical pollutants.
Geochemistry of later Pleistocene and Holocene palaeosols/soils in the Okstindan Mountains, Norway
Palaeosols and soils of early Holocene (≈9,000–10,000 yr BP) and Neoglacial (<1200 yr BP) ages from three sections in the Okstindan Mountains in central Norway were analyzed to determine their geochemical compositions. Four buried horizons and a surface sample all had significant water/organic contents. The highest Br (and also Th, U and possibly the REEs) contents were associated with the highest water/organic contents. From the rare earth and other elemental concentration variations, it appears that the three sections were formed from three parent materials, different horizons of which have been affected by weathering and plants.
