UPDATE: Please note this trip is now full. On Sunday, January 27, join the Angola Field Group for a geological field trip to Bengo province led by geologist Tako Koning, departing Luanda at 7:00 AM and returning around 5:00 PM. Scroll down for a map with locations.
We will drive north from Luanda to Barra do Dande to see outcrops consisting of Cretaceous-age fossiliferous, marine sedimentary rocks. These strata are interesting from a paleo-environmental standpoint of view and they are also of economic significance since they are the cap rocks to the reservoirs which produce oil in the shallow water areas offshore Soyo and Cabinda.
We will continue for 10 km northeast on the road to the Lifune River where we will examine some historically well known naturally-occurring oil seeps in Libongos, today an asphalt quarry. Records indicate that as early as 1820, the Portuguese shipped out barrels of asphalt probably from the Libongos seeps to Lisbon and Rio de Janeiro to use as calking to prevent leakage of ships. If time allows, we will visit a second asphalt quarry as we loop south to Caxito. The entire area we will be traversing is known as the Kwanza Sedimentary Basin.
We will then travel south to Caxito to the nearby water falls at Sassa to view ancient (2 billion-year-old) Precambrian granite outcrops and where we will have a late lunch (you pack your own lunch). If time permits, we will visit the nearby Mabubas Hydroelectric Dam, recently rehabilitated.
This field trip will also stop at Pangila Bridge to review some of the historical events which occurred here including the famous Quifangondo battle of November 10, 1975 which secured MPLA as the reigning party in Luanda, just prior to Angola achieving independence on November 11, 1975.
