CLONBUR ROCK SPECIMENS Some of the rocks collected during field trips from the Clonbur centre showing the great diversity of geology in the area. The top of a Silurian rugose coral from Kilbride. Often known as Horn Corals, they had a calcite skeleton and it is thought that they may have had stinging cells to help capture prey. Many of the original rocks have been deformed by great forces as the Earth’s plates pushed against each other. Dalradian schist A weathered breccia, a type of rock occurring at Mount Gable. Breccias were formed by the accumulation of rock debris which over time have become bonded together by finer materials into solid rock. Quartzite from Mamturks, a hard and brittle rock that originated from sand. Small colonies of calcified Silurian corals from Kilbride Peninsula that once flourished in the Iapetus Ocean .
