[BPT03-05] Biomineralization as the basis for understanding proxie incorporation
Keywords:Biomineralisation, trans-membrane transport, Proxies, Foraminifera, geochemistry
There are currently two models proposed for the biomineralization in Foraminifera that are fundamentally different but maybe not mutually exclusive. One model, is based on vacuolarisation of seawater while the other model (Trans-Membrane Transport model) is based on active pumping of Ca2+ ions during chamber formation. I will introduce the TMT model and discuss it in the context of additional, mostly experimental, data that has been generated over the last 30 years.
