Humboldt Programme Detail V7‐1.doc POST CONFERENCE EXCURSIONS Saturday 17 January, 2009 1. Beaches, lagoons and sand dunes: coastal environments north of Cape Town Leaders: John Compton and post graduate students, University of Cape Town. Depart at 9 am and return by 6 pm. We will travel 100 km north of Cape Town to explore the many different coastal environments along the west coast of South Africa visiting Langebaan Lagoon in the West Coast National Park and the phosphatic Pliocene fossil beds of the West Coast Fossil Park. We will see modern beach, rocky headland, salt marsh, lagoon and sand dune environments and compare them with Pleistocene deposits including aeolianite and calcrete. The depositional environments will be discussed in terms of palaeoclimate and sea‐level fluctuations on Holocene and glacial/interglacial timescales. 2. Circumnavigating the Cape Peninsula Leaders: Maarten de Wit and John Rogers, University of Cape Town. Depart at 8h30 am and return by 6 pm. We will travel around the Cape Peninsula a thin finger of land stretching southward from the central city of Cape Town to Cape Point at its southern tip, a distance of approximately 60 km. Its highest point is Table Mountain (1086 m above sea level), which lies immediately south of the central city, and mountains form a ridge down the centre of much of the Peninsula. The rocks comprise igneous, sedimentary and metamorphic types, with spectacular examples of each, including the famous Cape Granite‐Malmesbury metasediments contact that helped resolve 19th Century debate between Hutton and Werner about origin of granites. Charles Darwin later (1891) wrote a detailed description of the Sea Point contact in his diary. The high and rugged mountains in immediate proximity to the sea make for some spectacular scenery. The Cape Peninsula is the heart of the Cape Floral Kingdom with more than 1500 indigenous plant species. Included in these tours: • Geology guide book with maps and illustrations • Park entrance fees • Packed lunch and drinks There will be short and easy walks on sand and rocks. The weather is likely to be warm to hot; 25‐33° C; bring proper clothing for the outdoors (hat, windbreaker, sun‐screen) and an extra bottle of water if required. There will be a chance to purchase snacks and drinks at and use toilet facilities en route. See http://www.humboldt5.uct.ac.za/ for more detailed information 17
