Faults - a Devonian basin on the Moray coast

Rob, thanks for another informative geological excursion. I really appreciate your illuminating commentaries, backed as they are by your lucid field sketches, and the wonderful mapping of Scotland's geology. I hope to get back there one day to experience some more of Scotland's geological delights

Thanks - hope you can get back to these outcrops too - they're great.

I am a metallurgist by training, but have always loved geology. I was wondering whether you ever use differential geometry in your work. David Pollard (Stanford) wrote an article in 2007 on its use for describing 3-D folds; he and Raymond Fletcher (Penn State) devoted a chapter to that use in their 2005 textbook, _Fundamentals of Structural Geology_ . Geometric Algebra (an extension of vector algebra and calculus) offers several advantages as a way of implementing differential geometry. Although the LinkedIn group that is associated with our channel is aimed primarily at pre-university students, our members include many experts who might be interested in collaborating with you.

Geometric Algebra in structural geology is often used by Prof. John Ramsay. For most of us, that is so difficult to understand.

another good vid. maybe get a better microphone for more views and subscribers

indeed - check out this year's films which are generally better....
