Northern Ireland Geology-Shale and Greywaches. Shale is a fine grained sedimentary rock which splits easily. It can contain fossils such as graptolites which are characteristic of the Silurian and Ordovician Periods. Some excellent shale outcrops with numerous graptolites can be found along the coast around Donaghadee.
Northern Ireland Geology-Dolerite. Dolerite is a volcanic rock. While similar to basalt, it contains crystals which can be seen with a hand lens. This indicates that it cooled a little more slowly than basalt. Typically it is found in volcanic plugs which channeled the basalt to the surface.Erosion since Tertiary times, 60 million years ago, has exposed these plugs.hile similar to basalt, it contains crystals which can be seen with a hand lens.
