Question

what are Clint, Grike and doline in geography?

Answer 1

As the ice-cap moved into the Burren from the north-east it carried with it some debris, such as the granite boulders (Glacial erratics) on the coast line. However, the main action of the glacier was to scour the rock clean off any superficial cover that formerly may have lain on the surface, thus exposing and smoothly polishing the underlying bedrock which we know today as the largest classic karst limestone pavements in these islands. Pavements are made up of two separate but integral parts known as clints and grykes. Clints are the blocks of limestone that constitute the paving, their area and shape is directly dependant upon the frequency and pattern of grykes. Grykes are the fissures that isolate the individual clints. The most dominant gryke system runs almost north to south and there is a secondary less-developed system at right angles to it.
