Advancing planktonic foraminifera Mg/Ca thermometry: a microanalytical perspective

Sadekov, Aleksey Yu

Description

Microanalytical techniques, specifically laser ablation - inductively coupled plasma mass spectrometry (LA-ICPMS) and electron microprobe analysis(EMPA), have been used to determine Mg/Ca compositional variation within and between tests of planktonic foraminifera. Micro-scale characterization of this increasingly widely-used seawater temperature proxy has allowed scrutiny of the factors that limit its applicability as well as the development of new microanalysis-based Mg/Ca proxy calibrations...[Show more]
