Abstract

The present study on bulk carbonate 87Sr/86Sr stratigraphy represents a companion work to earlier research that presented a conodont apatite-based Ordovician seawater 87Sr/86Sr curve for the Tremadocian-KatianStages (485-445 Ma). Here, we directly compare the curve based on conodont apatite (includi...
