A Review of Research Progress on Re-Os Isotopic System of Carbon-enriched Geological Samples

Yankuang ceshi, 2023
Re and Os are relatively enriched in organic-enriched sedimentary rocks under an anoxic environment due to their organophilic property, and the seawater Os isotopic composition is recorded during the deposition of sedimentary rocks.
