Carbonate cements are quite common and plentiful in clastic sequences. They profoundly effect the standard of hydrocarbon reservoirs and provide very important details on palaeoenvironments and the chemical composition and move styles of fluids in sedimentary basins. regardless of this value, their distribution styles in time and area and their geochemical evolution usually are not but deeply explored and elucidated. This designated book includes 21 assessment papers and case reviews on carbonate cementation in clastic sequences written by way of invited experts at the topic. those papers current a large and deep insurance that improve our wisdom approximately carbonate cementation in quite a few clastic depositional environments, tectonic settings and burial histories. The publication might be of designated curiosity to researchers, petroleum geologists and academics and scholars on the postgraduate point. while you're a member of the overseas organization of Sedimentologists, for buying info, please see:

On Biomineralization

Concentrating on the fundamental ideas of mineral formation by means of organisms, this accomplished quantity explores questions that relate to a wide selection of fields, from biology and biochemistry, to paleontology, geology, and clinical learn. Preserved fossils are used to this point geological deposits and archaeological artifacts.

Sediments, Diagenesis, and Sedimentary Rocks, Volume 7: Treatise on Geochemistry

This quantity covers the formation and biogeochemistry of various vital sediment forms from their preliminary formation via their conversion (diagenesis) to sedimentary rocks. the amount offers with the chemical, mineralogical, and isotopic houses of sediments and sedimentary rocks and their use in studying the surroundings of formation and next occasions within the historical past of sediments, and the character of the ocean-atmosphere approach via geological time.

Application of Geochemical Tracers to Fluvial Sediment

This e-book takes an in-depth examine the idea and strategies inherent within the tracing of riverine sediments. tested tracers comprise multi-elemental focus info, fallout radionuclides (e. g. , 210Pb, 137Cs, 7Be), radiogenic isotopes (particularly these of Pb, Sr, and Nd), and novel (“non-traditional”) sturdy isotopes (e.
