GEOGRAPHY 

Granite is an older rock than chalk. Chalk formed during the Cretaceous period – some 65 to 145 mya (any idea of time within is acceptable) whilst granite formed 280 mya during Permian (according to NT book) or during Devonian, Silurian, Ordovician and Cambrian – all 359 mya or older. Thus granite is at least twice as old as chalk.

HISTORY
