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 activities

 

 

 

 

 

No paved roads in this region...on our way to 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...
