The GEOPIX photographs were taken by
Stephen Davies over a period of about forty years:
on field courses from the Geology Department of Cambridge University;
on field courses while teaching Geology to students of comprehensive schools;
on holiday in various parts of the world.
The explanatory notes which accompany the photographs are based on twenty years of setting
questions for and marking Geology examination papers up to A level standard.
Stephen is a
contributory author of the OCR Geology textbook published in 2008
