600 Million Years of Cynon Valley
Geological History
 

Acknowledgements

I would like to thank Dr Colin Rees, a contemporary of mine at Aberdare Boys Grammar School, for initially suggesting that I reviewed a geological introduction for another document, the result of which grew like a massive snowball, larger than either of us anticipated, into this work. His ability to convert my text and diagrams into the web pages produced here is also much appreciated and the final presentation owes much to his work. I would also like to thank a former colleague of mine at the University of Bristol, Professor Emeritus B P J Williams, later of Aberdeen University and now resident in his home town of Swansea, for reviewing the proof stage of the document and providing some useful inclusions.
 

Dedication

I would like to dedicate this work to the memory of the two men who sparked my interest in Geology at Aberdare Boys Grammar school, Mr. Meirion T Jenkins and Mr. Tom Evans. They prepared me well for subsequent university studies which eventually led me into a most interesting and worthwhile career. At a critical juncture during my school years the subject matter they offered me combined with their classroom style greatly influenced the path I chose, a decision I have never for one moment regretted. I can truly state that they influenced my life for the better and I am eternally grateful to them for so doing. I just hope that they would approve of what I have written here.
