The beds ofcolumnar basalt occur almost exclusivelyon the northern extremity. Besides the columnar strata, known as the GiantsCauseway, and the adjacent cliffs, similar strata are seen in other parts, particu-larly near the town of Antrim and Kilroot. Slievemish or Slemish Mountain isan enormous mass of greenstone, which also occurs in other localities.

The substance calledwood-coal occurs in thin strataat Portnoffer, Kiltymorris, Ballintoy, and elsewhere. All the other rocks of Antrim are beneath the basalticbeds in geological position. Thefirst is hard chalk, sometimescalled white limestone, whichaverages 200 feet in thicknessand occurs on the eastern and ~~ southern sides of the countyand on the southern coast of Rathlin Island.
