Example sentencesExamples
- Remarkably, when these carbon isotopes are traced back in geologic history, the average carbon isotopic composition of seawater and of most of the kerogen was similar to today.
- Retorting is the process of using heat to decompose the kerogen, converting it into a liquid called shale oil.
- It should be mentioned that the bulk of reduced carbon on Earth is sediment-bound kerogen, which most probably is of biological origin.
- These indices are independent of the organic matter abundance and strongly related to the elemental composition of kerogen.
- The bulk of organic matter in sedimentary rocks is in the form of kerogen: complex polymeric material that is insoluble in inorganic solvents, and difficult to analyse chemically.

Origin

Early 20th century: from Greek kēros 'wax' + -gen.
