A gift that arrives to us from Belgium on the part of Roger Warin. A few months ago I read this article in the always interesting Minibul published monthly by the AGAB (Association des Geologues Amateurs de Belgique) and since I read it I thought it would be great to spread it through FMF.

Roger Warin, always kind, has translated it into English language for us and this is the fascinating result that you can see in the images below or if you prefer to see it with even better image quality with this PDF.
Thanks Roger!
