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).
-
Both anticlines and synclines are the result of compressional stress.
