STABLE ISOTOPES IN MODERN BENTHIC FORAMINIFERA - A STUDY OF VITAL EFFECT | Academic Article individual record
abstract

Fundamental to the application of stable isotopes in paleoenvironmental studies is an understanding of the processes influencing the isotopic composition of biogenic carbonate. This paper examines carbon and oxygen isotopic equilibrium in foraminiferal calcite and aragonite, and the characteristics and causes of disequilibria (i.e., vital effect). Carbon isotopic compositions of certain benthic foraminifera record the chemistry of pore waters rather than bottom waters. Isotopic fractionation between the aragonitic Hoeglundina and ambient DIC shows a temperature dependence of -0.11per mille per oC. No temperature dependence is observed in the carbon isotopic fractionation of Uvigerina spp. -from Author
