The principles of natural light stable isotopic fractionation processes are used to quantitatively reconstruct marine paleoenvironments from the isotopic composition of fossil shells, as well as bulk and compound specific organic matter. Minor and trace elements in biogenic carbonates are introduced as additional proxies for physicochemical parameters. Their applicability and reliability together with isotopic proxies are discussed in a number of examples from selected case studies and a variety of geological times in Earths history
to achieve an advanced knowledge of stable isotope fractionation and trace element discrimination in marine biogeochemical processes and to understand and critical assesmentof the application of isotopes and trace elements in paleoenvironmental research
