Influence of peat formation conditions on the transformation of peat deposit organic matter
The paper studies the individual composition of n-alkanes, polycycloaromatic hydrocarbons, steroids, bi-, tri-, and pentacyclic terpenoids of two peat deposits of rich fen Kirek located in Western Siberia. Considering the individual n-alkanes concentrations, some indexes were calculated to estimate the humidity during peat formation. It was shown that the pH of peat medium primarily affects ste...
متن کاملMacrofossils from a Late-Glacial Deposit at Cambridge, Massachusetts
Macrofossils were isolated from late-glacial sediments exposed in open section in a building excavation at Cambridge, Massachusetts. The lower portion of the profile contained leaves of three species of herbaceous plant species now generally found in arctic or alpine regions, and fragments of a water beetle belonging to a species that now occurs characteristically in regions of boreal forest. T...
متن کاملInorganic and Organic Phosphorus Fractions in Peat from Drained Mires in Northern Finland
Soil samples from 15 eutrophic, 26 herb-rich, 15 tall-sedge, and 11 low-sedge drained peatland sites were analysed for easily soluble and aluminum, iron, and calcium bound phosphorus (P) using the Chang and Jackson sequential fractionation method. Compared to earlier investigations, where only total and easily soluble P contents (e.g. NH4OAc or dilute H2SO4 extractable P) in peat have been anal...
متن کاملEnvironmental impact of early Basque mining and smelting recorded in a high ash minerogenic peat deposit.
More than four metres of core, covering almost 5000 years of deposition, were collected in a high ash minerogenic peat deposit located in the High Aldudes valley (Basque country), an area well known for its mineral abundance, exploited from Roman Times at least. Although minerogenic peatlands are not generally considered as the best archives to reconstruct past atmospheric metal deposition hist...
متن کاملA new Burgess Shale-type deposit from the Ediacaran of western Mongolia
Preservation of soft-bodied organisms is exceedingly rare in the fossil record. One way that such fossils are preserved is as carbonaceous compressions in fined-grained marine sedimentary rocks. These deposits of exceptional preservation are known as Burgess Shale-type (BST) deposits. During the Cambrian Period, BST deposits are more common and provide a crucial view of early animal evolution. ...
