Laterites form by the leaching of the parent rock during the wet season, the resulting solution is brought to the surface during the dry season and removed, progressively depleting the soil of easily dissolved ions such as sodium, potassium, calcium and magnesium, leaving behind the more insoluble elements such as aluminium and iron oxides. As a result, weathering propagates downwards and inwards from cracks, creating “cores” of unweathered basalt that resemble pillow basalt. Deposits from these warm oceans include the Upper Cretaceous Chalks that can be seen all along the coast and in particular at Whiterocks Beach near Portrush. cooled , it contracted into the distinctive shapes. 3.
