There are abundant rock formations that have been deformed into hump-shaped strata known as anticlines, natural traps for oil.

Almost all rock formations have some inclination to the horizon, and the constant change of this inclination produces a series of waves, the crests of which are known as anticlines, and the troughs as synclines.

Large portions, especially of the upfolds, or "anticlines," of the waves, have been subsequently removed by erosion; the edges of these upfolds have been exposed, thus weathering out their fossilized contents, while downfolds are still buried beneath the earth for the explorers of coming centuries.

The second are important large and medium-scale folds (Weymouth, Lulworth and Purbeck anticlines), that verge north and contain axes that are parallel with and adjacent to the reactivated faults.

Slave River Plain is well-drained through porous bedrock, and exhibits sinkholes, sunken valleys, caves, submerged rivers, classic small anticlines and a complex recharge-discharge hydrology featuring swallow holes and cold springs, some with mineralized water.

The greater pressure results in anticlines and synclines that are inclined and asymmetrical (Figure 6).

Both anticlines and synclines are the result of compressional stress.
