Rodinia - a pre Cambrian continent

12-00 hrs: Let myself in for preparing a session for the U3A geology group on pre-cambrian rocks. This is the first continental mass (that is known about) - 750 million years ago. Scotland is attached to Canada - marked SC on the turqiose bit between the yellow (the core of ancestral Europe)  and dark blue (Gonwanaland) masses. 

 I think I am going to be beating my brain with this for the rest of the week - keeps me out of mischief I suppose - and also shows that I continue to improve.
