The Faulty Side of Howth Head

In this field trip we’ll examine the geology and structure of Howth Head.
We’ll see how the Howth Fault juxtaposes Carboniferous limestone and
Cambrian clastic sequences, which have very distinctive geological
histories and structures. The outcrops visited provide nice examples of
fractures, veins, minor faults, fault rock and fault-related mineralisation.
Not only does the Howth Fault highlight the structural characteristics of
those faults responsible for Ireland’s Zn-Pb deposits, it has also had an
important role in the formation of Dublin Bay. Places on this excursion
are limited to 30 and there is still some space left.
