Response of organic matter pore development to functional groups in overmature marine shale: Insights from AFM-IR spectroscopy

Response of organic matter pore development to functional groups in overmature marine shale: Insights from AFM-IR spectroscopy

Taking the Lower Silurian Longmaxi Formation shale in the Sichuan Basin as an example, this study employs atomic force microscopy-based infrared (AFM-IR) spectroscopy to analyze the submicron-scale molecular functional groups of different types and occurrences of organic matter. Combined with the qu...
