Field trip details:
This field trip will look at the upper Viséan shallow water open marine platform carbonates of the Burren region in the West of Ireland.
On day 1, we will look first at rocks of the uppermost Tubber Formation (upper Holkerian in age (MFZ12)), followed by limestones of the Burren Formation (Asbian (MFZ13-14) age) and finally cherty and more argillaceous limestones of the Slievenaglasha Formation (Brigantian (MFZ15) age.
On day 2, we will look at the siliciclastic rocks (shales, sandstones and mudstones) of the unconformably overlying Clare Shale and Gull Island Formation (Serpukhovian age (MFZ16)). Although karst features will accompany us on both days, on day 2 we will look at a swallow hole and discuss “Karst” in more detail.
Markus completed his first degree in Geology and Palaeontology at the University of Freiburg in Breisgau, Germany. He received a PhD from the National University of Ireland, Cork in 1994 with his subject area being the Old Red Sandstones and (sub)-Volcanics of the Beara Peninsula in County Cork. Markus has extensive experience of working as a geologist in the Bedrock /Landmapping section of the GSI. After successful completion of the 100k project, work began on 50k mapping program. Since c. 2006 his work has concentrated on the undifferentiated Viséan rocks with current focus on East Galway and Roscommon.
