Title:
Triple oxygen (16O, 17O, 18O) and carbon (12C, 13C) isotope variations in bioapatite of small mammals-new insights concerning the reconstruction of palaeo-CO2 concentrations and palaeotemperatures
Description:
Die Verhältnisse der stabilen Isotope des Sauerstoffs (16O, 17O, 18O) und des Kohlenstoffs (12C, 13C) im biogenen Apatit des Zahn- und Knochenmaterials von Säugetieren lassen Rückschlüsse auf die Isotopie der entsprechenden Sauerstoff- und Kohlenstoffquellen zu. Die Isotopenverhältnisse dieser Quellen (z.B. Trinkwasser, Luftsauerstoff, Nahrung) sind an bestimmte Umwelt- und Klimabedingungen wie Temperatur, Luftfeuchtigkeit, CO2-Konzentration, Bioproduktivität, Art der Vegetation, Grad der Vegetationsdichte etc. geknüpft. Bestimmt man die Sauerstoff- und Kohlensoffisotopenverhältnisse in dia...
The ratios among the stable isotopes of oxygen (16O, 17O, 18O) and carbon (12C, 13C) in biogenic apatite of mammal teeth and bones have the potential to provide insight into the isotopic composition of the respective oxygen and carbon sources. The isotope ratios of these sources (e.g. drinking water, air oxygen, diet) are connected to specific environmental and climatic conditions, such as temperature, relative humidity, CO2 concentration, bioproductivity, palaeovegetation and vegetation density. Analysis of the oxygen and carbon isotope composition of diagenetically unaltered skeletal tiss...
