2nd Year Field Trip

The focus of the 2nd year Field Trip is the New Bethesda area of the Eastern Cape Province. The course incorporates an introduction to the examination, description, and basic interpretation of geological features in the field. The area lends itself to use bedform features in horizontally-layered fluvially-deposited clastic sediments as examples. The Karoo is also rich in fossils documenting the paleo-flora and -fauna of the Eastern Cape, with special emphasis on the Permian life forms for which the Eastern Cape is best known.

The excursion includes geological stops at:

  • the classic Brantjieshoekte location to examine preserved evidence of migrating river channel deposits and volcanic ash layers,
  • the geological museum and fossiliferous palaeo-riverbed in New Bethesda, and examples of fossils both in-situ and in collections. The process of fossil location, identification, and preparation is also highlighted. This visit also highlights the geological history of the Karoo and the largest mass extinction even in the Earth’s history at the Permian-Triassic boundary.
  • igneous dolerite sills related to the Karoo Large Igneous Province near Graaf Reinet. The emplacement, uplift, and erosion of these sills are the main geological features we will discuss.

Students conduct field examinations and prepare reports (which are assessed), linking their coursework in the Sedimentology and Paleontology modules to their field observations and the acquired data. This Field Trip is planned to be run in the winter vacation and is managed by Prof Steve Prevec.
