Namibia 2009 Etendeka
Large Igneous Province In November 2009, I joined a large,
international group of geoscientists to the Etendeka volcanic province
of Namibia, following a conference in Johannesburg, South Africa, which
honoured Kevin Burke and Lew Ashwal for their 80th and 60th birthday,
respectively. During this short, but amazing trip we collected
paleomagnetic samples of the 132 Ma old Etendeka Large Igneous
Province, which was erupted as enormous basalt lavas. Only a small
portion is found in Namibia (where you can still follow individual
lavas over tens of kilometers), the bulk is found at the other side of
the South Atlantic in Argentina, formed by the Parana volcanics. The
Etendeka Large Igneous Province formed during the earliest stages of
South Atlantic opening, and we tested whether the paleomagnetic poles
of Parana coincide with the Etendeka, as they should. This site shows
the team, the work, and the zoo we've been working in. The crew

the camp Or no road at all, and just cruising through
the scrubs Crew deciding where to drill Beautiful basaltic feeder dike (black wall),
crosscutting a Cretaceous dune field (reddish colour) Main purpose was to collect paleomagnetic
samples of the lavas, which I am doing here... Field lunch Walking back to the cars after a day of
sampling in 40 degrees Celcius... Morgan, getting on that Great field outfit :) Lew, helping Morgan out Moving to the next offroad site... With consequences...7 flat tires in 3 days Site... Trishya going at it and some more... And doing the admin Local village Amazing landscapes... View from an average site Wildlife Africa's wildlife is fantastic, and Namibia was
no exception... Baboon with kid Single elephant bull Giraffe The jackal... Korhaan...they sound like frogs :) Female Kudu Male kudu Mad Russian, chasing a giraffe (and creating a
stampede among zebras that lasted for 15 minutes) Gemsbok, or Oryx Oryces with calves Ostriches Pufadder, pretty poisonous fellow Springbok Steenbok ...and zebras. It was great fun sampling in the
zoo :) |
