Ostracod shells, formed from a complex arrangement of low-Mg calcite crystals around organic fibrils that include protein and chitin, have been the subject of geochemical investigations for over 50 years. Trace-element (especially Mg and Sr) and stable-isotope (δ18O and δ13C, δ11B and 87Sr/86Sr) determinations have been used extensively to reconstruct lake hydrochemistry and temperature and, to a lesser degree, ocean bottom-water temperatures. Additional developments include analyses of Fe, Mn...[Show more]
