  • Of or pertaining to compression, that is, to the strain due to a stress, such as hydrostatic pressure, which tends to produce diminution of volume without shearing. See elasticity.

  • Fires, power failures, transit delays and more than a few sunburns were being attributed to the heat, which was caused by a high pressure area over the West Coast that created what meteorologists call compressional heating.

  • In this orogeny, compressional forces squished sedimentary deposits that existed between the converging continental plates and rocks at the margin of the Eurasian and Indian plates upward in elevation.

  • The later two stages of this model involve tectonic convergence of crustal plates which provides the compressional and tensional stresses that produce rock deformation, uplift, and faulting.

  • When the compressional forces become greater than the rocks ability to deform, faulting occurs.

  • However what the lecture did show me was that I need to go back and look at Big Picture geology ie how compressional and extentional basins fit in with plate tectonics.

  • The underlying sedimentary rocks accumulated in pulses of sedimentation in a depositional basin that developed in response to compressional tectonics in the Cape Fold belt, to the south and south-east, which was the area of provenance for much of the Karoo Supergroup.

  • In the orogenic stage of mountain building, the accumulated sediments become deformed by compressional forces from the collision of tectonic plates.

  • This for me was a fun mind teasing, problem solving lecture in which I guessed why there where extention faults at pretty much right angles to compressional features.

  • Reverse faults develop when compressional forces exist (Figure 10).
