Applications of Organic Petrology

Facets of organic petrology have found many applications in fundamental and applied earth sciences. Vitrinite reflectance measurements for example, are commonly used in petroleum exploration, coal rank determination, basin modeling, and minerals exploration. Maceral analysis is used in petroleum source rock characterization, blending of coals for coke-making, and interpretation of paleodepositional environments. Solvent extraction pyrolysis/GC/MS studies are used in oil/source rock correlations, and biomarker studies among others. Fluorescence microscopy is another commonly used method of characterizing the compositional evolution of sedimentary organic matter, particularly from the standpoint of oil generation during organic maturation.
