The theme for the upcoming Accretionary Wedge is ‘weird geology’. In his contribution, Simon Wellings takes a look at what might superficially appear to be an unlikely subject: the chalk that forms the rolling hills of southern England:
No texture, no mineralogical variation, no structure, what a bore; when I moved ‘down South’ and first encountered it I was almost offended by its dullness. I’m a hard-rock man by preference, but even the Carboniferous sediments I grew up with have cross-bedding, variation in colour and other nice things that distract you from the fact that they are only sediments. Chalk is weirdly dull.
