SUMMARY

The London Basin is fundamentally capable of drifting east-west, contrary to the assumption that it only moves north-south. This conclusion is supported by its classification as an 'early' aulacogen, which indicates a weak zone susceptible to tectonic stress. The regional stress field, influenced by the African plate's northward movement and the rotation of Iberia and Western Europe, plays a significant role in this drift. The discussion dismisses the relevance of Wilson Cycle subduction zones for the near future, asserting that geological processes are too slow to impact the London Basin significantly.

PREREQUISITES
  • Understanding of aulacogen geology
  • Knowledge of tectonic plate movements
  • Familiarity with regional stress fields in geology
  • Basic concepts of the Wilson Cycle
NEXT STEPS
  • Research the geological characteristics of aulacogens
  • Study the effects of tectonic plate interactions on regional geology
  • Explore the implications of the Wilson Cycle on continental drift
  • Investigate the geological history of the African plate and its influence on Europe
USEFUL FOR

Geologists, tectonic researchers, and students studying regional geology and plate tectonics will benefit from this discussion.

Is London Basin fundamentally (by definition) capable of drifting east-west, or only north-south?
 
Earth sciences news on Phys.org
I've a vague recollection that the Eastern part is an 'early' aulacogen related to the faulting and rifting in eg North Sea. This would make it a weak-zone for any tectonic stress, be that lateral or extensional...

You'd have to look at the regional stress-field due African plate's sorta-Northward plus clock-wise progress, and second-order stuff due interposed Iberia / Western Europe getting pushed about / rotated...

At least London Basin need not consider Wilson Cycle subduction zones & consequences for near-future, or even several millennia. IMHO, it is not speculation to say such processes are simply too slow. Should Gibraltar shelf spawn an Atlantic-swallowing trench, would take a geological age before that spreads up coast, or down-goings become volcanic up-comings per Caribbean Arc...
 
Found the answer. London Basin is able to drift east-west. It is the "average" of Earth crustal plates that must not drift east or west.
