I'm searching for an equation to relate the Mg/Ca ratio with temperature in the planktonic foraminiferan Turborotalita quinqueloba. It appears that multi-species calibrations previously studied do not include this species, so I am wondering if the relationship has been investigated.
Thanks in advance,
John

thank you for your response. My understanding is that magnesium enters the calcite of all foraminifera, driven by temperature, but the relationship differs in species-specific ways (the "vital effects"). While the association between Mg incorporation and temperature is widely studied in several species, I can't seem to find any literature specifically on T. quinqueloba. However, I was not aware that non-magnesian species exist, so this might be the explanation after all. Would you mind elaborating on this concept, or pointing me in the direction of some literature on foraminifera excluding Mg from their tests?Thanks again,
John
