A Karst Dome, The Burren

A view on Newtown Castle Ballycahill in County Clare - The Burren (Irish: Boireann, meaning "great rock", Boirinn, the dative form, is the modern form used by the Ordnance Survey) is a karst-landscape region or alvar in northwest County Clare, in Ireland. It is one of the largest karst landscapes in Europe. ...The rolling hills of Burren are composed of limestone pavements with criss-crossing cracks known as "grikes", leaving isolated rocks called "clints". The region supports arctic, Mediterranean and alpine plants side-by-side, due to the unusual environment. The limestones, which date from the Visean stage of the Lower Carboniferous, formed as sediments in a tropical sea approximately 350 million years ago. The strata contain fossil corals, crinoids, sea urchins and ammonites. Glaciation during the Quaternary period facilitated greater denudation. The result is that the Burren is one of the finest examples of a glacio-karst landscape in the world. (wikipedia)
