− | The table below shows examples of the relationships between [[Petroleum generation|hydrocarbon generation]] zones, maturity, and transformation ratio for standard types II and III kerogens, based on a specific burial and thermal history model. The most significant difference is in the depth to the onset of oil generation, where [[depth::1000 m]] separates the top of the oil windows of these two kerogen types.
