− | If a sample being analyzed for richness is not in an immature state, then the present-day maturation level of the interval needs to be determined to establish an initial (prematuration) organic carbon value for the interval. The measured TOC value is not indicative of the sample's source potential. | + | If a sample being analyzed for richness is not in an immature state, then the present-day [[maturation]] level of the interval needs to be determined to establish an initial (prematuration) organic carbon value for the interval.
