This fieldtrip led by Brian McConnell (GSI, Land Mapping Unit) will focus primarily on the Ordovician volcanic and sedimentary fill of the South Mayo Trough basin, including the Lough Nafooey volcano, basin-margin conglomerates, and ignimbrite sheets. Some older, basin-bounding rock units and the overlying Silurian unconformity will also be examined.
Booking essential as numbers are restricted. Contact: email@example.com or HowardFox41@gmail.com
