We have measured δ44/42Ca of laboratory-precipitated calcite growth in an experimental setup that closely replicates stalagmite formation. Calcium solutions were dripped onto two different substrates in tightly-controlled conditions and calcite precipitated due to rapid CO₂ degassing. With seeded glass slides as the substrate, we observe a Ca isotope ratio in the calcite which is ~0.5‰ per amu lower than that in the growth solution. This fractionation is generally almost twice that...Expand abstract
