The second part of the book is devoted to considering the evolution of the sulphur cycle in the Holocene, i.e. the last ten thousand years. The authors of this part (Chapter 5-Brimblecombe, Hammer, Rodhe, Ryaboshapko and Boutron) are interested in atmospheric aspects of the sulphur cycle and quite naturally concentrate on this component of the. Diffuse metal pollution from mining impacted sediment is widely recognised as a potential source of contamination to river systems and may significantly hinder the achievement of European Union Water Framework Directive objectives. Redox-transitional zones that form along metal contaminated river banks as a result of flood and drought cycles could cause biogeochemical changes that alter the Cited by:
Another factor which might influence changes in concentrations of elements in the soils or sediments is the presence of acid rain. Energy consumption and population growth in the last two centuries resulted in an increased production of sulphur and nitrogen oxides and release of these compounds into the atmosphere.

The sulfur cycle over geological periods can be represented by the simplified cycle shown in Figure 5(a).A central feature of this cycle is marine sulfate, which may be crystallized as sulfate evaporites or biologically reduced to sulfidic sediments (Holser et al., ).In the long term this sulfide becomes fixed by reaction with iron in a process that can be represented as.
This over-estimation of re- active iron in euxinic-type conditions can be recognized by constant DOP values less than 1. Bulk sediment composition The depth distributions of total iron, sulphur, and organic carbon contents, and of the isotopic composition of sulphur and organic carbon of sediments in core P3 at station K4 are shown in Fig.

Freshwater sediments act as both a source and a sink for biologically important materials such as phosphorus, carbon, nitrogen, sulfur, and silicon. Furthermore, sediments are known to play an active role in regulating cycles of trace metals, radionuclides, and xenobiotics (Jones and Bowser, ).Cited by: Nitrogen Cycling in Sediments.
corresponding with the well-understood carbon-nitrogen biogeochemistry for heterotrophic denitrification process. this paper provides new insights on sulphur. Most studies on organosulphur compounds in marine sediments have focused on hydrophobic compounds, for example, thiophenes3–6, sulphur-containing hopanoids7 and volatile compounds.
Hydrothermal diagenesis during the Zagros Orogeny produced three phases of saddle dolomites (SD1, SD2, and SD3) and two phases of blocky calcites (CI and CII) in the studied sections of Bekhme Formation (Fm) (Campanian–Maastrichtian).

There are two different approaches to predictive models of hydrocarbon source rocks. One approach focuses on mechanisms for accumulation of organic-carbon-rich sediments, in particular whether high organic productivity in surface waters, lack of dilution by clastic or carbonate sediment, or anoxic conditions are critical triggers (Demaison and Moore, ; Pedersen and Calvert, ; Arthur.
The book on deposition, diagenesis, and weathering of organic matter-rich sediments is a summary of seven years of research work of the author at the Institute of Petroleum and Organic Geochemistry in J}lich. It contains a comparision of various depositional environments (lakes, deltas, seas)with respect to organic matter characteristics, a.
