Biominerals and Biomaterial

Chapter
Part of the Advances in Isotope Geochemistry book series (ADISOTOPE)

Abstract

Biominerals are important archives for various paleo-environmental proxies, and consequently, the understanding of biomineralisation related element and isotope fractionation is vital for reliable climate reconstructions. The Ca isotope composition of biominerals has been investigated to explore its potential for paleo-environmental reconstructions and to better understand biomineralisation processes. The overall range of Ca isotope fractionation reported for biominerals resembles that of inorganic minerals, but shows different responses to changes of environmental parameters such as fluid composition and growth rates. In this chapter, we review Ca isotope fractionation characteristics of biominerals from different taxa with respect to biomineralisation processes and potential proxy applications. Available data of alkaline earth metal isotope systems (Mg, Sr) are included for comparison.
