nikkii Posted September 22, 2018 Share Posted September 22, 2018 I have recently been reading a lot of papers of different paleothermometers. The Calcium in calcium carbonate can get replaced by Mg and Sr and people use the ratios of Mg/Ca and Sr/Ca to predict past ocean surface temperatures. What I can't seem to understand is why the Mg/Ca and Sr/Ca show opposite trends with temperature such that as temperature increases Mg/Ca increases while Sr/Ca decreases. I would have thought they would both increase. Could someone please explain this to me? Thank you Link to comment Share on other sites More sharing options...
John Cuthber Posted September 22, 2018 Share Posted September 22, 2018 In both cases the ratio (lighter ion/ heavier ion) increases. 1 Link to comment Share on other sites More sharing options...

Unlike some I am not above learning from others, in fact I am pleased you have told me something I didn't know or spot, though I tried to look it up. Thank you. +1 Edited September 22, 2018 by studiot Link to comment Share on other sites More sharing options...
