Laser Raman spectroscopy parameters of pure organic matter (e.g., vitrinite, solid bitumen) in sedimentary rocks have been widely applied for maturity determination, but there is a lack of relevant studies on mineral-organic aggregation (MOA) directly based on shale whole rock samples. A recent paper has revealed a good correlation between laser Raman spectroscopy parameters of MOA and maturities for high-overmature marine shales, providing a new way to address maturity evaluation.
