Summary of site:

The context for this site is given in the Slieve Gullion Ring – Overview, site 1118.

This outcrop shows the convoluted lobes and crenulations of the contact between the high temperature molten dolerite of layer 4 and the cooler but still molten granophyre below. Net veining resulting from the interaction of the two is prominently displayed.

This site is a key component of the suite of sites selected as the framework to our understanding of the evolution of Slieve Gullion and is internationally important.
