The preservation of silicon isotope ratios in cherts and recrystallized sponge spicules

Key Points

• Cherts maintained silicon isotope ratios during recrystallization of sponge spicules, demonstrating preservation capabilities.
• Analysis showed significant preservation of silicon isotope ratios, with implications for biological and geological interpretations.
• Geochemical analysis of samples indicates that the preservation of isotopes is vital for studying past environments and biological processes.
• Findings suggest improved methods for using silicon isotopes as biomarkers in geological research.
