==Determining source rock potential==

The quantity of organic matter is commonly assessed by a measure of the [[total organic carbon (TOC)]] contained in a rock. Quality is measured by determining the [[Kerogen types|types of kerogen]] contained in the organic matter. Thermal maturity is most often estimated by using [[Thermal_maturation#Vitrinite|vitrinite]] reflectance measurements and data from [[Pyrolysis gas chromatography|pyrolysis]] analyses.
