Biomarker and carbon isotope signatures constrain changes in organic matter inputs during the Oligocene-Miocene interval of Kutch Basin, western India: climatic and tectonic implications

Key Points

• Significant variations in organic matter inputs were noted during the Oligocene-Miocene transition.
• The study highlights biomarker and carbon isotope signatures to evaluate climatic impacts on sedimentation.
• Observational analysis across western India's Kutch Basin utilized geological sampling and geochemical methods.
• Understanding these shifts may enhance insights into the region's climatic and tectonic evolution.
