A go-back or return journey; in geology, a type of fault line that reverses or retraces previous movement.
From 'go' (Old English 'gān') + 'back' (from Old Norse 'bak'). The combination describes movement returning to a previous point or, in geological contexts, reversal of tectonic direction.
In geology, a 'goback' reveals tectonic drama—it's evidence that the earth's plates didn't move in one direction but reversed, pushing rocks backward along fault lines. This tells stories of collision zones where continents fought for position!
