Virtual Fieldtrip 1 - Wednesday 23rd June 00.00-02.00 UTC
Taranaki Coast, New Zealand
Kia ora koutou! We look forward to welcoming you to New Zealand to join us on an amazing journey to the North Island’s Taranaki-Waikato regions. Over a distance of ~50 km, the coastal cliffs along the modern coastline provide excellent exposures of Miocene-age deep-water clastic rocks, recognised as a world-class location for studying deep-water stratigraphic architecture and depositional systems. We will be visiting a variety of submarine landslide outcrops from the sand-dominated basin floor-to-base of slope Mount Messenger Formation and the volcaniclastic Mohakatino Formation. The submarine landslides we will visit represent the products of mass wasting derived from the eastern margin of the Taranaki Basin and transported into deep water settings during periods of high sedimentation and slope progradation. We will be able to see the wide variety of submarine landslide morphologies, internal stratigraphy and structural features at each of these ‘windows’ into the past, that will be of broad interest to a variety of submarine landslide research disciplines. The team from GNS Science will be your guides, with a little help from some special guests.

Virtual fieldtrip 2 - Wednesday 23rd June 12.00-17.00 UTC
Co Clare Deep-water basin to Delta tops
Fáilte! The cliffs of the Atlantic coastline and outer Shannon estuary of south Co. Clare are remarkable for their world-class exposures of Upper Carboniferous deep water, slope and delta deposits. These include spectacular examples of the fabrics formed by deepwater fan lobes, channels, and soft sediment deformation. The high sea cliffs provide large 'reservoir-scale' slices through the various deposits. In addition in recent years this area of Co. Clare has also become a test area for high resolution sequence stratigraphy whose concepts have far-reaching applications in the exploration and exploitation of hydrocarbons while providing an understanding how offshore basins fill. UCD has led a series of behind-outrcrop drill sites over the past decade and a visitors’ field centre has now developed to house the cores and allow geologists to have access to it.
The virtual fieldtrip will give you a window into this world-class geological site and associated data.
