Overburden rock is the total stratigraphic section above the [[source rock]].<ref name=ch04r61>Magoon, L. B., and W. G. Dow, 1994, The Petroleum System--From Source to Trap: [http://store.aapg.org/detail.aspx?id=1022 AAPG Memoir 60], p. 3–24.</ref> The thickness and age of overburden rock provides a history of the rate of burial of a [[source rock]] toward and through the increasing temperature domains of the basin. This includes the range of temperatures necessary for cracking kerogens into hydrocarbons. (See also [[Kerogen type and hydrocarbon generation]].)

Because the depth to the probable [[source rocks]] of the East Breaks 160-161 field hydrocarbons is unknown, multiple working hypotheses must be considered.
