Paleoclimate inferred from earthworms calcite granules d18O analyses

Earthworm calcite granules are a bio-indicator and climatic proxy of absolute air and soil temperature in the context of Last Glacial loess and therefore can help to reconstruct the paleoclimate.

This Application Note shows the d¹⁸O analysis of earthworm calcite granules using the isoprime precisION dual inlet IRMS and the iso FLOW headspace analyzer.
