    Very interesting presentation and poster. It is definitely not my field but you did a good job with your explanation.

    I guess the question I had is the following. What is the motivation to distinguish origins of the ochre pigments from the three or four sites that you chose? And I am still not sure how much sensitivity was achieved in determining differences between these three sites. Finally, how much more different if you were to obtain ochre from more distant sites, for example, outside the Karonga region?
