AI Thread Summary
The London Basin is capable of drifting east-west, contrary to assumptions that it may only move north-south. This capability is linked to its geological structure, particularly its classification as an early aulacogen, which suggests it is a weak zone for tectonic stress. The regional stress field influenced by the African plate's northward movement and rotational dynamics of Iberia and Western Europe plays a significant role in this drift. Additionally, the London Basin is not affected by Wilson Cycle subduction zones, as such processes occur over geological timescales that are too slow to impact the basin in the near future. Overall, the average behavior of Earth's crustal plates indicates that while individual regions like the London Basin can drift, the broader tectonic framework remains stable.

Is London Basin fundamentally (by definition) capable of drifting east-west, or only north-south?

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.
