Fluvio-deltaic sedimentation in the Western Irish Namurian Basin of County Clare, Ireland: facies, sedimentary heterogeneity and controls on deposition

Leaders: Jim Best, Jeff Peakall and Paul Wignall

Dates: July 20th to 24th

Cost: £ 375

The Western Irish Namurian Basin (WINB) of County Clare has become a world-renowned region for studying the nature of a Carboniferous basin infill, from oceanic black shales to fluvio-deltaic deposits. The area has also become a mecca for geologists in recent decades for examining deepwater sediments, the nature of cyclicity in such a basin fill and its sequence stratigraphic interpretation. All of this is possible due to the superb, and truly breathtaking, exposures of these sediments along the coastline of County Clare. Exposure in the Western Irish Namurian Basin (WINB)

This field trip will be based near the village of Spanish Point, County Clare, and will focus on sediments within the fluvio-deltaic Tullig and Kilkee cyclothems along the coastline. The trip will visit the key outcrops of fluvio-deltaic sediments within the WINB in order to demonstrate the nature and internal heterogeneity of the fluvial sediments, the stacking patterns of channels within larger composite channel sandbodies, the relationship of the alluvial sediments to both the underlying deltaic lobes and overlying coals and trangressive sequences, the nature of possible seismically-induced deformation and delta-lobe front soft-sediment instabilities, and the palaeogeographic context of these fluvial sequences. The trip will detail the changing nature of fluvial sedimentation from proximal fluvial feeder channel to distal distributary channel and interdistributary bay sequences. The exposures will also allow discussion of several basin palaeogeographic reconstructions, the sequence stratigraphic interpretation of these sediments, as well as their use as reservoir analogues. All of this will be set within some superb coastline scenery and the appreciable culinary and liquid benefits of Irish field work.

Logistics

The field trip will commence in Dublin on Saturday 20th July (flights from Leeds and Manchester are available on the Saturday morning). The group will be met at Dublin Airport at 1:30 PM. We will travel across Ireland by coach to our hotel at Spanish Point, County Clare, where we will be based for 4 nights. The trip will end on Wednesday July 24th, with the coach travelling back to Dublin for mid-afternoon (participants can fly out of Dublin from c. 16.00 or arrange overnight accommodation in Dublin).

Participants need good walking shoes or boots and waterproof clothing (this is the coast of Ireland after all).

Field Trip Fee includes 3-star Hotel (single room for 4 nights, with breakfast and dinner), transport from and to Dublin airport, all internal travel and field guide.

Note: Flights to and from Dublin are not provided. Lunches are also not provided, and we will stop at various places where lunches can be purchased.
