Wedges of agglomerate have been found around Ballygally Head, showing that there were several stages of eruption, allowing tuff to form before the vent was blown out and once more filled with magma. There are tall columns in places around Ballygally Head, similar to the basalt columns found at the Giant's Causeway, but these are dolerite, a rock similar to basalt but which cooled more slowly, held inside the volcano vent, and so had time to grow larger crystals.
Scawt Hill, another volcanic plug 5 km west north west of Ballygally, is an internationally important site for geology due to the rare minerals found there. It is a protected Area of Special Scientific Interest.
