The impermeable rock overlying an oil or gas reservoir that tends to prevent migration of the reservoir fluids from the reservoir. 5, record 1, English, - cap%20rock
Record number: 1, Textual support number: 1 CONT
Oil and gas become trapped in the subsurface where there is a barrier formed by impermeable rocks, such as well-cemented lithologies, mudrock and evaporite beds. These impermeable lithologies are known as cap rocks. The hydrocarbons will find their way around the cap-rock barrier unless there is some form of hydrocarbon trap that prevents further upward migration. 6, record 1, English, - cap%20rock
Record number: 1, Textual support number: 1 OBS
All cap rocks are impermeable, therefore making the terms "impermeable cap rock" and "impervious cap rock" redundant. 7, record 1, English, - cap%20rock

[The] solid rock present beneath any soil, sediment or other surface cover. 6, record 2, English, - bedrock
Record number: 2, Textual support number: 1 CONT
The bedrock which underlies the overburden is an important consideration and may control the contaminant migration pathway. For example, a porous sandstone formation may decrease travel times to the biosphere, particularly if the facility [an abandoned mine used for the disposal of low-level radioactive wastes] is in a groundwater recharge zone. 7, record 2, English, - bedrock

bed-rock : terme anglais désignant le substratum rocheux sous les éluvions ou alluvions plus meubles. 9, record 2, French, - substratum
Record number: 2, Textual support number: 2 OBS
Les termes «substratum rocheux» et «roche en place», s'ils traduisent tous les deux le terme anglais «bedrock», sont employés dans des contextes différents. «Substratum rocheux» désigne la roche sur laquelle repose une formation géologique ou un dépôt donné, tandis que «roche en place» est un terme général désignant une formation rocheuse quelconque recouverte ou non de sédiments ou d'une autre formation. P. ex., un affleurement peut être constitué de roche en place. 16, record 2, French, - substratum
